Pentacel


Generic Name: diphtheria, haemophilus, pertussis, tetanus, and polio (dif THEER ee a, hem OFF il us, per TUS is, TET a nus, POE lee oh)

Brand Names: Pentacel


What is diphtheria, haemophilus influenzae, pertussis, tetanus, and polio vaccine?

Diphtheria, haemophilus influenzae, pertussis, tetanus, and polio are serious diseases caused by bacteria.


Diphtheria causes a thick coating in the nose, throat, and airway. It can lead to breathing problems, paralysis, heart failure, or death.


Haemophilus influenzae can cause minor flu symptoms or it can cause more serious symptoms such as swelling around the throat, making it hard to swallow or breathe. Haemophilus influenzae can also cause swelling of the membranes around the brain and spinal cord (meningitis).


Pertussis (whooping cough) causes coughing so severe that it interferes with eating, drinking, or breathing. These spells can last for weeks and can lead to pneumonia, seizures (convulsions), brain damage, and death.


Tetanus (lockjaw) causes painful tightening of the muscles, usually all over the body. It can lead to "locking" of the jaw so the victim cannot open the mouth or swallow. Tetanus leads to death in about 1 out of 10 cases.


Polio affects the central nervous system and spinal cord. It can cause muscle weakness and paralysis. Polio is a life-threatening condition because it can paralyze the muscles that help you breathe.


Diphtheria, haemophilus influenzae, pertussis, and polio are spread from person to person. Tetanus enters the body through a cut or wound.


The diphtheria, haemophilus influenzae, pertussis, tetanus, and polio vaccine is used to help prevent these diseases in children who are ages 6 weeks through 4 years (before the 5th birthday).


This vaccine works by exposing your child to a small dose of the bacteria or a protein from the bacteria, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body.


Like any vaccine, the diphtheria, haemophilus influenzae, pertussis, tetanus, and polio vaccine may not provide protection from disease in every person.


What is the most important information I should know about this vaccine?


The diphtheria, haemophilus influenzae, pertussis, tetanus, and polio vaccine is given in a series of shots. The first shot is usually given when the child is 2 months old. The booster shots are then given at 4 months, 6 months, and 15 to 18 months of age. Your child's individual booster schedule may be different from these guidelines. Follow your doctor's instructions or the schedule recommended by the health department of the state you live in.


Be sure your child receives all recommended doses of this vaccine. If your child does not receive the full series of vaccines, he or she may not be fully protected against the disease.


Your child can still receive a vaccine if he or she has a cold or fever. In the case of a more severe illness with a fever or any type of infection, wait until the child gets better before receiving this vaccine.


Your child should not receive a booster vaccine if he or she had a life-threatening allergic reaction after the first shot.

Keep track of any and all side effects your child has after receiving this vaccine. When the child receives a booster dose, you will need to tell the doctor if the previous shots caused any side effects.


Becoming infected with diphtheria, haemophilus influenzae, pertussis, tetanus, or polio is much more dangerous to your child's health than receiving the vaccine to protect against these diseases. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.


What should I discuss with my healthcare provider before receiving this vaccine?


Your child should not receive this vaccine if he or she has ever had a life-threatening allergic reaction to any vaccine containing diphtheria, haemophilus, pertussis, tetanus, or polio. Your child should not receive this vaccine if the child has had a decreased level of consciousness within the past 7 days, or if the child has severe or uncontrolled epilepsy or other seizure disorder.

Your child may not be able to receive this vaccine if he or she has ever received a similar vaccine that caused any of the following within 48 hours:



  • a very high fever (over 104 degrees);




  • excessive crying for 3 hours or longer;




  • fainting or going into shock;




  • seizure (convulsions); or




  • Guillain-Barré syndrome (within 6 weeks after receiving a vaccine containing tetanus).



Before receiving this vaccine, tell the doctor if your child has:



  • a history of seizures;




  • a neurologic disorder or disease affecting the brain (or if this was a reaction to a previous vaccine);




  • if the child is using steroid medication or receiving cancer chemotherapy or radiation treatment; or




  • a weak immune system caused by disease, bone marrow transplant, or by using certain medicines or receiving cancer treatments.



Your child can still receive a vaccine if he or she has a cold or fever. In the case of a more severe illness with a fever or any type of infection, wait until the child gets better before receiving this vaccine.


How is this vaccine given?


This vaccine is given as an injection into a muscle. Your child will receive this injection in a doctor's office or other clinic setting.


The diphtheria, haemophilus influenzae, pertussis, tetanus, and polio vaccine is given in a series of shots. The first shot is usually given when the child is 2 months old. The booster shots are then given at 4 months, 6 months, and 15 to 18 months of age. Your child's individual booster schedule may be different from these guidelines. Follow your doctor's instructions or the schedule recommended by the health department of the state you live in.


Your doctor may recommend treating fever and pain with an aspirin-free pain reliever such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil, and others) when the shot is given and for the next 24 hours. Follow the label directions or your doctor's instructions about how much of this medicine to give your child.


It is especially important to prevent fever from occurring in a child who has a seizure disorder such as epilepsy.

What happens if I miss a dose?


Contact your doctor if you will miss a booster dose or if you get behind schedule. The next dose should be given as soon as possible. There is no need to start over.


Be sure your child receives all recommended doses of this vaccine. If your child does not receive the full series of vaccines, he or she may not be fully protected against the disease.


What happens if I overdose?


An overdose of this vaccine is unlikely to occur.


What should I avoid before or after receiving this vaccine?


Follow your doctor's instructions about any restrictions on food, beverages, or activity after receiving the vaccine.


This vaccine side effects


Your child should not receive a booster vaccine if he or she had a life-threatening allergic reaction after the first shot. Keep track of any and all side effects your child has after receiving this vaccine. When the child receives a booster dose, you will need to tell the doctor if the previous shots caused any side effects.

Becoming infected with diphtheria, haemophilus influenzae, pertussis, tetanus, or polio is much more dangerous to your child's health than receiving the vaccine to protect against these diseases. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.


Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if the child has any of these serious side effects:



  • extreme drowsiness, fainting;




  • fussiness, irritability, crying for an hour or longer;




  • seizure (black-out or convulsions); or




  • high fever.



Less serious side effects may include:



  • redness, pain, tenderness, or swelling where the shot was given;




  • low fever;




  • mild fussiness or crying;




  • headache or tiredness;




  • joint pain, body aches;




  • loss of appetite; or




  • mild nausea, diarrhea, or vomiting.



This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.


What other drugs will affect diphtheria, haemophilus influenzae, pertussis, tetanus, and polio vaccine?


Before receiving this vaccine, tell the doctor about all other vaccines your child has recently received.

Also tell the doctor if your child has received drugs or treatments in the past 2 weeks that can weaken the immune system, including:



  • an oral, nasal, inhaled, or injectable steroid medicine;




  • medications to treat psoriasis, rheumatoid arthritis, or other autoimmune disorders, such as azathioprine (Imuran), efalizumab (Raptiva), etanercept (Enbrel), leflunomide (Arava), and others; or




  • medicines to treat or prevent organ transplant rejection, such as basiliximab (Simulect), cyclosporine (Sandimmune, Neoral, Gengraf), muromonab-CD3 (Orthoclone), mycophenolate mofetil (CellCept), sirolimus (Rapamune), or tacrolimus (Prograf).



If your child is using any of these drugs, this vaccine may not work as well.


This list is not complete and there may be other drugs that can affect this vaccine. Tell your doctor about all the prescription and over-the-counter medications your child has received. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your child's doctor.

Although donated human plasma is screened, tested, and treated to reduce the risk of it containing anything that could cause disease, there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.


How should I use fibrinogen?


Fibrinogen is given as an injection through a needle placed into a vein. Your doctor, nurse, or other healthcare provider will give you this injection. You may be shown how to use your medicine at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of needles, IV tubing, and other items used in giving the medicine.


You will need to mix fibrinogen with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medication. Do not mix fibrinogen with any other medicines, or give other medicines through the same IV line.


Fibrinogen contains no preservative. Once you have pierced the rubber top of a vial with a needle, you must use that vial right away or throw it away. Do not shake the medication vial (bottle). Vigorous shaking can ruin the medicine. Do not draw your fibrinogen dose into a syringe until you are ready to give yourself an injection. Do not use the medication if it has changed colors or has any particles in it. After mixing fibrinogen with a diluent, use it right away or store the mixture at room temperature and use it within 24 hours. The mixed medicine should be clear or slightly colored. Do not use the mixed medication if it has changed colors, is cloudy, or has any particles in it.

Each single-use vial (bottle) of this medicine is for one use only. Throw away the vial after one use, even if there is still some medicine left in it after injecting your dose.


To be sure this medication is helping your condition, your blood may need to be tested often. This will help your doctor determine how long to treat you with fibrinogen. Do not miss any follow-up visits to your doctor.


Use each disposable needle only one time. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.


Store the unmixed dry powder in a refrigerator or in a dark cool place. Keep the medicine protected from light and do not allow it to freeze. Throw away any unused vial after the expiration date on the label has passed.

What happens if I miss a dose?


Use the missed dose as soon as you remember. If it is almost time for your next dose, wait until then to use the medicine and skip the missed dose. Do not use extra medicine to make up the missed dose.


What happens if I overdose?


Seek emergency medical attention if you think you have used too much of this medicine.

Symptoms of a fibrinogen overdose are not known.


What should I avoid while taking fibrinogen?


Follow your doctor's instructions about any restrictions on food, beverages, or activity while you are using fibrinogen.

guanethidine and hydrochlorothiazide


Generic Name: guanethidine and hydrochlorothiazide (gwhan ETH i deen and hye droe klor oh THYE a zide)

Brand Names: Esimil


What is guanethidine and hydrochlorothiazide?

Guanethidine lowers blood pressure by decreasing the levels of certain chemicals in your blood. This allows your blood vessels (veins and arteries) to relax and your heart to beat more slowly and easily.


Hydrochlorothiazide is a thiazide diuretic (water pill). It helps to lower your blood pressure and decrease edema (swelling) by increasing the amount of salt and water you lose in your urine.


Guanethidine and hydrochlorothiazide is used to treat high blood pressure.


Guanethidine and hydrochlorothiazide may also be used for purposes other than those listed in this medication guide.


What is the most important information I should know about guanethidine and hydrochlorothiazide?


Stand up slowly from a sitting or lying position. Guanethidine and hydrochlorothiazide may make you feel dizzy. Do not stop taking guanethidine and hydrochlorothiazide suddenly. Even if you feel better, you need this medication to control your condition. Stopping suddenly could cause severe high blood pressure, anxiety, and other dangerous side effects.

Tell your doctor and dentist that you are taking this medication before having surgery.


Who should not take guanethidine and hydrochlorothiazide?


Do not take guanethidine and hydrochlorothiazide if you have an allergy to sulfa-based drugs such as sulfa antibiotics. You may have an allergic reaction to hydrochlorothiazide.

You must not take guanethidine and hydrochlorothiazide if you



  • have pheochromocytoma;




  • have congestive heart failure; or




  • are taking a monoamine oxidase inhibitor (MAOI) such as isocarboxazid (Marplan), phenelzine (Nardil), or tranylcypromine (Parnate).



Before taking this medication, tell your doctor if you have



  • peptic ulcer disease (stomach ulcers) or other stomach problems,




  • ulcerative colitis,




  • gallstones,



  • kidney or liver disease,


  • diabetes,




  • gout,




  • a collagen vascular disease such as systemic lupus erythematosus,




  • high levels of cholesterol or triglyceride (types of fat) in your blood,




  • pancreatitis,




  • asthma, or




  • any type of heart disease.



You may require a lower dose or special monitoring during therapy with guanethidine and hydrochlorothiazide if you have any of these conditions.


Guanethidine and hydrochlorothiazide is in the FDA pregnancy category B. This means that it is not expected to harm an unborn baby. Do not take this medication without first talking to your doctor if you are pregnant. Guanethidine and hydrochlorothiazide passes into breast milk and may harm a nursing infant. Do not take this medication without first talking to your doctor if you are breast-feeding a baby. Guanethidine and hydrochlorothiazide has not been approved for use by children.

How should I take guanethidine and hydrochlorothiazide?


Take guanethidine and hydrochlorothiazide exactly as directed. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.


Take each dose with a full glass of water. Take guanethidine and hydrochlorothiazide with food or milk if it upsets your stomach.

Do not stop taking guanethidine and hydrochlorothiazide. Stopping suddenly could make your condition much worse or cause very serious side effects.


Store this medication at room temperature away from moisture and heat.

See also: Guanethidine and hydrochlorothiazide dosage (in more detail)

What happens if I miss a dose?


Take the missed dose as soon as you remember. However, if it is almost time for your next dose, skip the dose you missed and take only your next regularly scheduled dose. Do not take a double dose of this medication.


What happens if I overdose?


Seek emergency medical attention.

Symptoms of a guanethidine and hydrochlorothiazide overdose include low blood pressure (fainting, dizziness, weakness); sleepiness; uncontrollable hand, leg, or arm movements; a slow pulse; low body temperature; diarrhea; increased urination; vomiting, and slow breathing.


What should I avoid while taking guanethidine and hydrochlorothiazide?


Use caution when rising from a sitting or lying position, especially first thing in the morning. You may become dizzy while taking guanethidine and hydrochlorothiazide, and you may fall and injure yourself if you get up quickly.

Do not let yourself become overheated in hot weather or during exercise, and use caution if you have a fever. These situations increase the effects of guanethidine and hydrochlorothiazide, and you may become very dizzy.


Avoid prolonged exposure to sunlight. Hydrochlorothiazide may increase the sensitivity of your skin to sunlight. Use a sunscreen and wear protective clothing when exposure to the sun is unavoidable. Avoid alcohol while taking guanethidine and hydrochlorothiazide. Alcohol, which will further lower your blood pressure, will also increase the drowsiness caused by guanethidine and hydrochlorothiazide and may increase dizziness. Use caution even with small amounts of alcohol.

Avoid a diet high in salt. Too much salt will cause your body to retain water and will decrease the effects of hydrochlorothiazide.


Do not take any over-the-counter cough, cold, allergy, sleep, or diet medications without first asking your doctor or pharmacist. These products will interfere with your guanethidine and hydrochlorothiazide therapy.


Use caution when you are driving, climbing ladders, or performing other hazardous activities until you know how guanethidine and hydrochlorothiazide affects you. If it makes you dizzy or drowsy, avoid these activities.


Tell your doctor and dentist that you are taking this medication before having surgery.


Guanethidine and hydrochlorothiazide side effects


If you experience any of the following serious side effects, stop taking guanethidine and hydrochlorothiazide and seek emergency medical attention:

  • an allergic reaction (difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives);




  • a very irregular heartbeat;




  • heart failure (shortness of breath, swelling of ankles or legs, sudden weight gain of 5 pounds or more);

  • unusual fatigue;




  • abnormal bleeding or bruising;




  • yellow skin or eyes;




  • confusion;

Voluven





Dosage Form: injection, solution
FULL PRESCRIBING INFORMATION

Indications and Usage for Voluven


Voluven® (6% hydroxyethyl starch 130/0.4 in 0.9% sodium chloride injection) is indicated for the treatment and prophylaxis of hypovolemia.


It is not a substitute for red blood cells or coagulation factors in plasma.



Voluven Dosage and Administration


Voluven® is administered by intravenous infusion only. The daily dose and rate of infusion depend on the patient’s blood loss, on the maintenance or restoration of hemodynamics and on the hemodilution (dilution effect). Voluven® can be administered repetitively over several days. [see Warnings and Precautions (5)]


The initial 10 to 20 mL should be infused slowly, keeping the patient under close observation due to possible anaphylactoid reactions. [see General Warnings and Precautions (5.1)]



Adult Dose


Up to 50 mL of Voluven® per kg of body weight per day (equivalent to 3 g hydroxyethyl starch and 7.7 mEq sodium per kg of body weight). This dose is equivalent to 3500 mL of Voluven® for a 70 kg patient.



Pediatric Dose


Limited clinical data on the use of Voluven® in children are available. In 41 children including newborns to infants (< 2 years), a mean dose of 16 ± 9 mL/kg was administered. The dosage in children should be adapted to the individual patient colloid needs, taking into account the disease state, as well as the hemodynamic and hydration status. The safety and efficacy of Voluven® have not been established in the age group of 2 to 12 years. Use of Voluven® in children > 12 years is supported by evidence from adequate and well-controlled studies of Voluven® in adults and by data from children < 2 years old. [see Pediatric Use (8.4)]



Directions for Use of Voluven®



















  • Check the solution composition, lot number and expiry date, inspect the container for damage or leakage, if damaged do not use.             


  • Use opening aid to remove over-wrap.


  • Identify the blue infusion (administration) port. 


  • Break off the blue tamper-evident cover from the freeflex® infusion port.


 

  • Hang the bag on the infusion stand. Press drip chamber to get fluid level. Prime infusion set. Connect and adjust the flow rate.


  • Close roller clamp. Insert the spike until the clear plastic collar of the port meets the shoulder of the spike.

  • Use a non-vented standard infusion set.

  • Close air inlet.


 





  1. Do not remove the freeflex® IV container from its overwrap until immediately before use.

  2. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

  3. Do not administer unless the solution is clear, free from particles and the freeflex® IV container is undamaged.

  4. Voluven® should be used immediately after insertion of the administration set.

  5. Do not vent.

  6. If administered by pressure infusion, air should be withdrawn or expelled from the bag through the medication/administration port prior to infusion.

  7. Discontinue the infusion if an adverse reaction occurs.

  8. It is recommended that administration sets be changed at least once every 24 hours.

  9. For single use only. Discard unused portion.

INCOMPATIBILITIES


The safety and compatibility of additives have not been established.

Dosage Forms and Strengths


500 mL freeflex® flexible plastic intravenous solution container are available. Each 100 mL contains 6 g hydroxyethyl starch 130/0.4 in isotonic sodium chloride injection.



Contraindications


The use of Voluven® is contraindicated in the following conditions:



  • known hypersensitivity to hydroxyethyl starch [see General Warnings and Precautions (5.1)]




  • fluid overload (hyperhydration) and especially in cases of pulmonary edema and congestive heart failure




  • renal failure with oliguria or anuria not related to hypovolemia




  • patients receiving dialysis treatment




  • severe hypernatremia or severe hyperchloremia




  • intracranial bleeding.




Warnings and Precautions



General Warnings and Precautions


Anaphylactoid reactions (mild influenza-like symptoms, bradycardia, tachycardia, bronchospasm, non-cardiac pulmonary edema) have been reported with solutions containing hydroxyethyl starch. If a hypersensitivity reaction occurs, administration of the drug should be discontinued immediately and the appropriate treatment and supportive measures should be undertaken until symptoms have resolved. [see Adverse Reactions (6)]


Fluid status and rate of infusion should be assessed regularly during treatment, especially in patients with cardiac insufficiency or severe kidney dysfunction.


In cases of severe dehydration, a crystalloid solution should be given first. Generally, sufficient fluid should be administered in order to avoid dehydration.


Caution should be observed before administering Voluven® to patients with severe liver disease or severe bleeding disorders (e.g., severe cases of von Willebrand´s disease).



Monitoring: Laboratory Tests


Clinical evaluation and periodic laboratory determinations are necessary to monitor fluid balance, electrolyte concentrations, kidney function, acid-base balance, and coagulation parameters during prolonged parenteral therapy or whenever the patient’s condition warrants such evaluation.



Interference with Laboratory Tests


Elevated serum amylase levels may be observed temporarily following administration of the product and can interfere with the diagnosis of pancreatitis.


At high dosages the dilutional effects may result in decreased levels of coagulation factors and other plasma proteins and a decrease in hematocrit.



Adverse Reactions



Overall Adverse Reaction Profile


From the accumulated clinical development experience, expected adverse reactions after administration of Voluven® occurring in less than 10% of patients are as follows:


Immune system disorders (Rare, >0.01% to <0.1%): Products containing hydroxyethyl starch may lead to anaphylactoid reactions (hypersensitivity, mild influenza-like symptoms, bradycardia, tachycardia, bronchospasm, non-cardiac pulmonary edema). In the event of an intolerance reaction, the infusion should be discontinued immediately and the appropriate emergency medical treatment initiated. [see General Warnings and Precautions (5.1)]


Skin and subcutaneous tissue disorders (Common, >1 to <10%, dose dependent): Prolonged administration of high dosages of hydroxyethyl starch may cause pruritus (itching) which is an undesirable effect observed with all hydroxyethyl starches.


Investigations (Common, >1% to <10%, dose dependent): The concentration of serum amylase can rise during administration of hydroxyethyl starch and can confound the diagnosis of pancreatitis. At high doses the dilutional effects may result in decreased levels of coagulation factors and other plasma proteins and in a decrease of hematocrit. [see Interference with Laboratory Tests (5.3)]



Adverse Reactions in Clinical Trials


Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug may not reflect the rates observed in practice.


During clinical development, 471 patients were exposed to Voluven®, and a total of 768 patients received the hydroxyethyl starch 130/0.4 drug substance contained in Voluven® at different concentrations (2%, 4%, 6%, or 10%) and at cumulative doses of several mL up to 66 L1). The mean duration of treatment with hydroxyethyl starch 130/0.4 was 3.9 ± 3.3 days, mean cumulative doses were 3338 ± 3695 mL, and the longest follow-up period was 90 days.


In the US trial, 100 patients undergoing elective orthopedic surgery were treated either with Voluven® (N=49) or hetastarch (6% hydroxyethyl starch in 0.9% sodium chloride injection) (N=51) for intraoperative volume replacement. Mean infusion volumes were 1613 ± 778 mL for Voluven® and 1584 ± 958 mL for hetastarch.


Adverse reactions observed in at least 1% of patients: In the US trial comparing Voluven® with hetastarch, a possible relationship to Voluven® was reported in five cases in a total of three patients (aPTT elevated, PT prolonged, wound hemorrhage, anemia, pruritus). A possible relationship to hetastarch was reported in five patients (three cases of coagulopathy; two cases of pruritus). The three coagulopathy cases in the hetastarch group were serious and occurred in patients receiving more than the labeled ceiling dose (20 mL/kg), whereas no serious coagulopathy occurred in the Voluven® group.



Postmarketing Experience


The following adverse reactions have been identified during the post-approval use of Voluven® and other types of hydroxyethyl starch solutions. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.


The safety profile from postmarketing experience of Voluven® is not different from the profile obtained from clinical trials performed using the product.


Based on spontaneous reporting of hypersensitivity reactions, urticaria, bronchospasm, or hypotension were the most frequently reported serious adverse drug reactions for patients treated with Voluven®.


With the administration of hydroxyethyl starch solutions, disturbances of blood coagulation can occur depending on the dosage2).



Drug Interactions


No interactions with other drugs or nutritional products are known. The safety and compatibility of other additives have not been established [see Directions for Use of Voluven® (2.3)].



USE IN SPECIFIC POPULATIONS



Pregnancy


Pregnancy Category C. Voluven® has been shown to cause embryocidal or other adverse effects in rats and rabbits when given in doses 1.7 times the human dose. There are no adequate and well-controlled studies in pregnant women. Voluven® should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.


The type of hydroxyethyl starch present in Voluven® had no teratogenic properties in rats or rabbits. At 5 g/kg of body weight per day, administered as a bolus injection, fetal retardations and embryolethal effects were observed in rats and rabbits, respectively. In rats, a bolus injection of this dose during pregnancy and lactation reduced body weight of offspring and induced developmental delays. All adverse effects were seen exclusively at maternal toxic doses due to fluid overload. [see Toxicology (13.2.1)]


Fertility studies on directly exposed animals have not been conducted.



Labor and Delivery


Information on the use of Voluven® during labor or delivery is unknown.



Nursing Mothers


It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Voluven® is administered to a nursing woman.



Pediatric Use


In one trial, children including newborns to infants (< 2 years) undergoing elective surgery were randomized to receive Voluven® (N=41) or 5% albumin (N=41). The mean dose of Voluven® administered was 16 ± 9 mL/kg3).


Voluven® may be given to newborns only after a careful risk/benefit evaluation. The safety and efficacy of Voluven® have not been established in the age group of 2 to 12 years. Use of Voluven® in children > 12 years is supported by evidence from adequate and well-controlled studies of Voluven® in adults and by data from children < 2 years old. Dosage in children should be adapted to individual patient colloid needs, taking into account underlying disease, hemodynamics and hydration status. [see Pediatric Dose (2.2)]



Geriatric Use


Of the total number of subjects in clinical studies of Voluven® (N= 471), 32% were 65 years old and older while 7% were 75 and older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.



Renal Impairment


Voluven® is mainly excreted by the kidneys, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Volume status, infusion rate, and urine output should be closely monitored. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection. [see Pharmacokinetics (12.3)]



Drug Abuse and Dependence


Voluven® is not considered to be a drug of abuse potential.



Controlled Substance



Overdosage


As with all plasma volume substitutes, overdosage can lead to overloading of the circulatory system (e.g. pulmonary edema). In this case, the infusion should be stopped immediately and if necessary, a diuretic should be administered. [see General Warnings and Precautions (5.1)]

Freeflex® is collapsible and can be used in emergency cases for pressure infusion.



Voluven - Clinical Pharmacology



Mechanism of Action


Voluven® contains hydroxyethyl starch in a colloidal solution which expands plasma volume when administered intravenously. This effect depends on the mean molecular weight (130,000 daltons; range 110,000 – 150,000 daltons), the molar substitution by hydroxyethyl groups (0.4; range 0.38 – 0.45) on glucose units of the starch, the pattern of hydroxyethyl substitution (C2/C6 ratio) of approximately 9:1, and the concentration (6%), as well as the dosage and infusion rate.


Hydroxyethyl starch is a derivative of thin boiling waxy corn starch, which mainly consists of a glucose polymer (amylopectin) predominately composed of α-1-4-connected glucose units with several α-1-6-branches. Substitution of hydroxyethyl groups on the glucose units of the polymer reduces the normal degradation of amylopectin by α-amylase in the body. The low molar substitution (0.4) is the main pharmacological determinant for the beneficial effects of Voluven® on pharmacokinetics, intravascular volume and hemodilution4). To describe the molecular weight and molar substitution characteristics of the hydroxyethyl starch in Voluven®, the compound is designated as hydroxyethyl starch 130/0.4.



Pharmacodynamics


After isovolemic exchange of blood with 500 mL of Voluven® in healthy volunteers, blood volume is maintained for at least 6 hours.



Pharmacokinetics


The pharmacokinetic profile of hydroxyethyl starch is complex and largely dependent on its molar substitution as well as its molecular weight.4) When administered intravenously, molecules smaller than the renal threshold (60,000-70,000 daltons) are readily and rapidly excreted in the urine, while molecules with higher molecular weights are metabolized by plasma α-amylase prior to excretion via the renal route.


The mean in vivo molecular weight of Voluven® in plasma is 70,000 – 80,000 daltons immediately following infusion and remains above the renal threshold throughout the treatment period.


Following intravenous administration of 500 mL Voluven® to healthy volunteers, plasma levels of Voluven® remain at 75% of peak concentration at 30 minutes post-infusion and decrease to 14% at 6 hours post-infusion. Plasma levels of Voluven® return to baseline levels 24 hours following infusion. Plasma clearance, volume of distribution, and elimination half-life of Voluven® in healthy volunteers following IV administration of 500 mL were 31.4 mL/min, 5.9 liters, and 12 hours, respectively. Approximately 62 % of Voluven® was excreted as hydroxyethyl starch molecules in urine within 72 hours.


The pharmacokinetics of Voluven® are similar following single and multiple dose administration. No significant plasma accumulation occurred after daily administration of 500 mL of a 10% solution containing hydroxyethyl starch 130/0.4 over a period of 10 days. Approximately 70% of Voluven® was excreted as hydroxyethyl starch molecules in urine within 72 hours.


Renal Impairment:


Following a single intravenous administration of Voluven® (500 mL) in subjects with varying degrees of renal dysfunction, the AUC and clearance of Voluven® increased by 73% and decreased by 42% in patients, respectively, with creatinine clearance <50 mL/min as compared to patients with creatinine clearance >50 mL/min. However, terminal half-life and peak hydroxyethyl starch concentration were not affected by renal impairment. Plasma levels of Voluven® returned to baseline levels 24 hours following infusion. Approximately 59 % and 51 % of Voluven® were excreted as hydroxyethyl starch molecules in urine within 72 hours in patients with creatinine clearance ≥30 mL/min and <30 mL/min, respectively.


There are no data available on the use of Voluven® in patients undergoing hemodialysis.


Pharmacokinetic data in patients with hepatic insufficiency or in pediatric or geriatric patients are not available. Effects of gender or race on the pharmacokinetics of Voluven® have not been studied.



Nonclinical Toxicology



Carcinogenesis, Mutagenesis, Impairment of Fertility


Long-term studies in animals to evaluate the carcinogenic potential of Voluven® have not been performed. No mutagenic effects were observed with hydroxyethyl starch 130/0.4 10% solution in the following tests on mutagenic activity: Salmonella typhimurium reverse mutation assay (in vitro), mammalian cells in the in vitro gene mutation assay, assessment of the clastogenic activity in cultured human peripheral lymphocytes (in vitro), bone marrow cytogenetic test in Sprague-Dawley rats.


Fertility studies on directly exposed animals have not been performed.



Animal Pharmacology and/or Toxicology



Animal Toxicology and Pharmacology



Toxicology


Three-month repeat infusion toxicology studies were conducted in rats and dogs in which three groups of animals were administered daily intravenous infusion over three hours. Dosing volumes of either 60 or 90 mL/kg body weight of hydroxyethyl starch 130/0.4 (10% solution) or 90 mL/kg 0.9% sodium chloride injection were studied. Observed toxicity following repeat infusion of hydroxyethyl starch is consistent with the oncotic properties of the solution resulting in hypervolemia in the animals. There were no apparent gender-related effects on toxicity following repeat administration of hydroxyethyl starch 130/0.4 in rats or dogs.


In reproduction studies in rats and rabbits, hydroxyethyl starch 130/0.4 (10% solution) had no teratogenic properties. Embryolethal effects were observed in rabbits at 5 g/kg body weight/day. In rats, bolus injection of this dose during pregnancy and lactation reduced body weight of offspring and induced developmental delays. Signs of fluid overload were seen in the dams. Hydroxyethyl starch 130/0.4 (10% solution) was observed to have no effect in studies assessing skin sensitization, antigenicity, and blood compatibility.



Pharmacology


The pharmacodynamic effect of Voluven® was examined in a hemorrhagic shock model in conscious rats and a hemodilution model in dogs. In both studies the control group received pentastarch (6% hydroxyethyl starch 200/0.5).


Voluven® was as effective as pentastarch in maintaining cardiopulmonary function during isovolemic hemodilution in beagle dogs. In the three-hour follow-up period no additional administration of colloid was necessary.


There were no differences in long-term survival of rats after a single administration of Voluven® and pentastarch solutions following induced hemorrhagic shock (67% and 50% blood loss). In the 67% induced bleeding group receiving Voluven® (N=6), the survival rate was 83% which is within the normal range for this type of experiment. In the corresponding pentastarch group, survival was 100%. Infusion of Ringer's lactate resulted in a 50% survival rate after a 50% blood loss and a 0% survival after a 67% blood loss.


After multiple intravenous infusions of 0.7 g per kg body weight per day of 10% hydroxyethyl starch 130/0.4 or 10% hydroxyethyl starch 200/0.5 solution during 18 consecutive days, the plasma hydroxyethyl starch concentration in rats treated with hydroxyethyl starch 130/0.4 was lower compared to rats treated with hydroxyethyl starch 200/0.5. Hydroxyethyl starch 130/0.4 was eliminated faster than hydroxyethyl starch 200/0.5. In both groups, clear signs of hydroxyethyl starch tissue storage were detected in lymph nodes and spleen. Numerous empty vacuoles in macrophages were observed. Only minimal cellular vacuolization was found in the liver and kidney. Histochemical differences between the groups were not observed.


A study with 10% radiolabeled 14C-hydroxyethyl starch 130/0.4 and 10% 14C- hydroxyethyl starch 200/0.5 solutions was carried out6). In animals treated with hydroxyethyl starch 130/0.4, radioactivity decreased from 4.3% of the total administered dose (2.6 g hydroxyethyl starch 130/0.4 per animal) on day 3 to 0.65% on day 52. In animals treated with hydroxyethyl starch 200/0.5, the 14C-activity decreased from 7.7% of the total administered dose (2.7 g hydroxyethyl starch 200/0.5 per animal) on day 3 to 2.45% on day 52. These results confirm the faster elimination and lower persistence of hydroxyethyl starch 130/0.4 in tissue.



Clinical Studies


Voluven® was studied in controlled clinical trials in adult and pediatric surgical patients and in patients in intensive care units. Clinical studies included patients undergoing various types of surgery (orthopedic, urologic, cardiac) and trauma intensive care for situations in which hypovolemia is treated (pre-, intra-, and postoperative) or prevented (autologous blood donation, acute normovolemic hemodilution, hypervolemic hemodilution before cardiac surgery). The safety and efficacy of Voluven® were compared to other colloidal plasma substitutes [pentastarch (6% hydroxyethyl starch 200/0.5), hetastarch (6% hydroxyethyl starch 450/0.7), gelatin solution or human serum albumin] in studies carried out in common clinical settings of volume replacement therapy. Perioperative fluid administration of Voluven® ranged from 500 to 4500 mL/day in surgical patients, and cumulatively, 6 to 66 L during stays in intensive care units following traumatic brain injury.


A prospective, controlled, randomized, double-blind, multi-center trial of 100 patients undergoing elective orthopedic surgery was conducted in the US evaluating Voluven® (N=49) compared to hetastarch (6% hydroxyethyl starch in 0.9% sodium chloride injection) (N =51) for intraoperative volume replacement therapy7). The primary efficacy variable, total volume of colloid solution required for intraoperative volume replacement therapy, was equivalent for the two treatment groups. Mean volume infused was 1613 ± 778 mL for Voluven® and 1584 ± 958.4 mL for hetastarch. The ratio Voluven®/hetastarch was estimated as 1.024 with a 95% confidence interval (0.84, 1.25), which was included within the equivalence range of (0.55, 1.82) prespecified in the study protocol. This indicated that Voluven® and hetastarch have similar efficacy as intraoperative volume replacement therapy in major orthopedic surgery.


A second objective of the trial was to show superiority for safety between Voluven® and hetastarch. Four safety endpoints were prospectively defined and compared in a sequential manner (in order to preserve the type–1 error rate, i.e., observing a difference where none actually exists). Per protocol, if there was no difference found between treatment arms for the first safety endpoint (EBL), the remaining endpoints were to be considered exploratory analyses requiring additional studies for confirmation.


Overall, no significant differences in serious adverse events were noted between the two treatment arms, but three cases of serious coagulopathy occurred in the hetastarch treatment arm. All three subjects received high doses (>3000 mL; labeled ceiling dose = 20 mL/kg) of the product, which are known to increase the risk of bleeding. Since EBL for the two treatment arms was not statistically different (95% confidence interval includes unity), the difference observed for Factor VIII (see table, below) must be interpreted with caution. An exploratory analysis of total erythrocyte volume transfused (8.0 mL/kg vs. 13.8 mL/kg, Voluven® vs hetastarch, respectively) must also be viewed with caution.

*Exploratory analyses

There was no statistically significant difference between the two treatment groups with respect to the secondary efficacy endpoints of hemodynamic stability, body temperature, hemodynamic parameters, blood pressure, central venous pressure, heart rate, fibrinogen and platelet count.


In addition to the US trial, three non-US trials were conducted with the primary objective of showing equivalency (based on mean difference rather than mean ratio as in the US study) between Voluven® and pentastarch in maintaining or restoring hemodynamic parameters. The largest of the three trials (N=100) met the prespecified boundary (-500 mL, 500 mL), but the two smaller studies (N=52 and N=59) did not.


In exploratory analyses, the effect of Voluven® on coagulation parameters (von Willebrand factor, Factor VIII, and Ristocetin cofactor) was shown to be significantly lower than pentastarch at one or more time points (US and non-US trials). These findings are consistent with the lower molar substitution, lower average molecular weight and narrower molecular weight distribution of Voluven® as compared to pentastarch resulting in a lower in vivo molecular weight and increased elimination from the circulation.


A safety profile of Voluven® at least as favorable as for pentastarch was also demonstrated in studies where Voluven® was administered at doses higher (up to 50 mL/kg or 3 g/kg) than for pentastarch (up to 33 mL/kg or 2 g/kg) in clinical settings where large or repetitive doses are administered.
