Mivacron uses


INDICATIONS AND USAGE

Mivacron is a short-acting neuromuscular blocking agent indicated for inpatients and outpatients, as an adjunct to general anesthesia, to facilitate tracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation.

CONTRAINDICATIONS

Mivacron is contraindicated in patients with known hypersensitivity to the product and its components.

WARNINGS

Anaphylaxis

Severe anaphylactic reactions to neuromuscular blocking agents, including Mivacron, have been reported. These reactions have in some cases been life-threatening and fatal. Due to the potential severity of these reactions, the necessary precautions, such as the immediate availability of appropriate emergency treatment, should be taken. Precautions should also be taken in those individuals who have had previous anaphylactic reactions to other neuromuscular blocking agents since cross-reactivity between neuromuscular blocking agents, both depolarizing and non-depolarizing, has been reported in this class of drugs.

Administration

Mivacron should be administered in carefully adjusted dosage by or under the supervision of experienced clinicians who are familiar with the drug's actions and the possible complications of its use. The drug should not be administered unless personnel and facilities for resuscitation and life support (tracheal intubation, artificial ventilation, oxygen therapy), and an antagonist of Mivacron are immediately available. It is recommended that a peripheral nerve stimulator be used to measure neuromuscular function during the administration of Mivacron in order to monitor drug effect, determine the need for additional drug, and confirm recovery from neuromuscular block.

Mivacron has no known effect on consciousness, pain threshold, or cerebration. To avoid distress to the patient, neuromuscular block should not be induced before unconsciousness.

Mivacron is metabolized by plasma cholinesterase and should be used with great caution, if at all, in patients known to be or suspected of being homozygous for the atypical plasma cholinesterase gene.

Mivacron Injection is acidic (pH 3.5 to 5) and may not be compatible with alkaline solutions having a pH greater than 8.5 (e.g., barbiturate solutions).

PRECAUTIONS

General

Although Mivacron is not a potent histamine releaser, the possibility of substantial histamine release must be considered. Release of histamine is related to the dose and speed of injection.

Caution should be exercised in administering Mivacron to patients with clinically significant cardiovascular disease and patients with any history suggesting a greater sensitivity to the release of histamine or related mediators (e.g., asthma). In such patients, the initial dose of Mivacron should be 0.15 mg/kg or less, administered over 60 seconds; assurance of adequate hydration and careful monitoring of hemodynamic status are important (see CLINICAL PHARMACOLOGY - Hemodynamics and Individualization of Dosages ).

Obese patients may be more likely to experience clinically significant transient decreases in MAP than non-obese patients when the dose of Mivacron is based on actual rather than ideal body weight. Therefore, in obese patients, the initial dose should be determined using the patient's ideal body weight (see CLINICAL PHARMACOLOGY - Hemodynamics and Individualization of Dosages ).

Recommended doses of Mivacron have no clinically significant effects on heart rate; therefore, Mivacron will not counteract the bradycardia produced by many anesthetic agents or by vagal stimulation.

Neuromuscular blocking agents may have a profound effect in patients with neuromuscular diseases (e.g., myasthenia gravis and the myasthenic syndrome). In these and other conditions in which prolonged neuromuscular block is a possibility (e.g., carcinomatosis), the use of a peripheral nerve stimulator and a dose of not more than 0.015 to 0.02 mg/kg Mivacron is recommended to assess the level of neuromuscular block and to monitor dosage requirements (see CLINICAL PHARMACOLOGY - Individualization of Dosages ).

Mivacron has not been studied in patients with burns. Resistance to nondepolarizing neuromuscular blocking agents may develop in patients with burns, depending upon the time elapsed since the injury and the size of the burn. Patients with burns may have reduced plasma cholinesterase activity which may offset this resistance (see CLINICAL PHARMACOLOGY - Individualization of Dosages ).

Acid-base and/or serum electrolyte abnormalities may potentiate or antagonize the action of neuromuscular blocking agents. The action of neuromuscular blocking agents may be enhanced by magnesium salts administered for the management of toxemia of pregnancy (see CLINICAL PHARMACOLOGY - Individualization of Dosages ).

No data are available to support the use of Mivacron by intramuscular injection.

Allergic Reactions

Since allergic cross-reactivity has been reported in this class, request information from your patients about previous anaphylactic reactions to other neuromuscular blocking agents. In addition, inform your patients that severe anaphylactic reactions to neuromuscular blocking agents, including Mivacron have been reported (see CONTRAINDICATIONS ).

Renal and Hepatic Disease

The possibility of prolonged neuromuscular block must be considered when Mivacron is used in patients with renal or hepatic disease. Most patients with chronic hepatic disease such as hepatitis, liver abscess, and cirrhosis of the liver exhibit a marked reduction in plasma cholinesterase activity. Patients with acute or chronic renal disease may also show a reduction in plasma cholinesterase activity (see CLINICAL PHARMACOLOGY - Individualization of Dosages ).

Reduced Plasma Cholinesterase Activity

The possibility of prolonged neuromuscular block following administration of Mivacron must be considered in patients with reduced plasma cholinesterase (pseudocholinesterase) activity.

Plasma cholinesterase activity may be diminished in the presence of genetic abnormalities of plasma cholinesterase (e.g., patients heterozygous or homozygous for the atypical plasma cholinesterase gene), pregnancy, liver or kidney disease, malignant tumors, infections, burns, anemia, decompensated heart disease, peptic ulcer, or myxedema. Plasma cholinesterase activity may also be diminished by chronic administration of oral contraceptives, glucocorticoids, or certain monoamine oxidase inhibitors and by irreversible inhibitors of plasma cholinesterase (e.g., organophosphate insecticides, echothiophate, and certain antineoplastic drugs).

Mivacron has been used safely in patients heterozygous for the atypical plasma cholinesterase gene. At doses of 0.1 to 0.2 mg/kg Mivacron, the clinically effective duration of action was 8 minutes to 11 minutes longer in patients heterozygous for the atypical gene than in genotypically normal patients.

As with succinylcholine, patients homozygous for the atypical plasma cholinesterase gene (one in 2500 patients) are extremely sensitive to the neuromuscular blocking effect of Mivacron. In three such adult patients, a small dose of 0.03 mg/kg (approximately the ED10-20 in genotypically normal patients) produced complete neuromuscular block for 26 to 128 minutes. Once spontaneous recovery had begun, neuromuscular block in these patients was antagonized with conventional doses of neostigmine. One adult patient, who was homozygous for the atypical plasma cholinesterase gene, received a dose of 0.18 mg/kg Mivacron and exhibited complete neuromuscular block for about 4 hours. Response to post-tetanic stimulation was present after 4 hours, all four responses to train-of-four stimulation were present after 6 hours, and the patient was extubated after 8 hours. Reversal was not attempted in this patient.

Malignant Hyperthermia

In a study of MH-susceptible pigs, Mivacron did not trigger MH. Mivacron has not been studied in MH-susceptible patients. Because MH can develop in the absence of established triggering agents, the clinician should be prepared to recognize and treat MH in any patient undergoing general anesthesia.

Long-Term Use in the Intensive Care Unit

No data are available on the long-term use of Mivacron in patients undergoing mechanical ventilation in the ICU.

Drug Interactions

Although Mivacron has been administered safely following succinylcholine-facilitated tracheal intubation, the interaction between Mivacron and succinylcholine has not been systematically studied. Prior administration of succinylcholine can potentiate the neuromuscular blocking effects of nondepolarizing agents. Evidence of spontaneous recovery from succinylcholine should be observed before the administration of Mivacron.

The use of Mivacron before succinylcholine to attenuate some of the side effects of succinylcholine has not been studied.

There are no clinical data on the use of Mivacron with other nondepolarizing neuromuscular blocking agents.

Isoflurane and enflurane (administered with nitrous oxide/oxygen to achieve 1.25 MAC) decrease the ED50 of Mivacron by as much as 25% (see CLINICAL PHARMACOLOGY - Pharmacodynamics and Individualization of Dosages ). These agents may also prolong the clinically effective duration of action and decrease the average infusion requirement of Mivacron by as much as 35% to 40%. A greater potentiation of the neuromuscular blocking effects of Mivacron may be expected with higher concentrations of enflurane or isoflurane. Halothane has little or no effect on the ED50, but may prolong the duration of action and decrease the average infusion requirement by as much as 20%.

Other drugs which may enhance the neuromuscular blocking action of nondepolarizing agents such as Mivacron include certain antibiotics (e.g., aminoglycosides, tetracyclines, bacitracin, polymyxins, lincomycin, clindamycin, colistin, and sodium colistimethate), magnesium salts, lithium, local anesthetics, procainamide, and quinidine. The neuromuscular blocking effect of Mivacron may be enhanced by drugs that reduce plasma cholinesterase activity (e.g., chronically administered oral contraceptives, glucocorticoids, or certain monoamine oxidase inhibitors) or by drugs that irreversibly inhibit plasma cholinesterase (see PRECAUTIONS - Reduced Plasma Cholinesterase Activity subsection).

Resistance to the neuromuscular blocking action of nondepolarizing neuromuscular blocking agents has been demonstrated in patients chronically administered phenytoin or carbamazepine. While the effects of chronic phenytoin or carbamazepine therapy on the action of Mivacron are unknown, slightly shorter durations of neuromuscular block may be anticipated and infusion rate requirements may be higher.

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis and fertility studies have not been performed. Mivacron was evaluated in a battery of four short-term mutagenicity tests. It was non-mutagenic in the Ames Salmonella assay, the mouse lymphoma assay, the human lymphocyte assay, and the in vivo rat bone marrow cytogenetic assay.

Pregnancy

Teratogenic Effects

Pregnancy Category C

Teratology testing in nonventilated pregnant rats and mice treated subcutaneously with maximum subparalyzing doses of Mivacron revealed no maternal or fetal toxicity or teratogenic effects. There are no adequate and well-controlled studies of Mivacron in pregnant women. Because animal studies are not always predictive of human response, and the doses used were subparalyzing, Mivacron should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Labor and Delivery

The use of Mivacron during labor, vaginal delivery, or cesarean section has not been studied in humans and it is not known whether Mivacron administered to the mother has effects on the fetus. Doses of 0.08 and 0.2 mg/kg Mivacron given to female beagles undergoing cesarean section resulted in negligible levels of the stereoisomers in Mivacron in umbilical vessel blood of neonates and no deleterious effects on the puppies.

Nursing Mothers

It is not known whether any of the stereoisomers of mivacurium are excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised following administration of Mivacron to a nursing woman.

Pediatric Use

Mivacron has not been studied in pediatric patients below the age of 2 years.

Geriatric Use

Mivacron was safely administered during clinical trials to 64 geriatric (greater than or equal to 65 years) patients, including 31 patients with significant cardiovascular disease (see PRECAUTIONS - General subsection). In general, the clearances of Mivacron are most likely lower, the duration may be longer, the rate of recovery may be slower, therefore, Mivacron requirements may be lower in geriatric patients (see CLINICAL PHARMACOLOGY - Special Populations - Geriatric Patients ).

ADVERSE REACTIONS

Observed in Clinical Trials

Mivacron was well tolerated during extensive clinical trials in inpatients and outpatients. Prolonged neuromuscular block, which is an important adverse experience associated with neuromuscular blocking agents as a class, was reported as an adverse experience in three of 2074 patients administered Mivacron. The most commonly reported adverse experience following the administration of Mivacron was transient, dose-dependent cutaneous flushing about the face, neck, and/or chest. Flushing was most frequently noted after the initial dose of Mivacron and was reported in about 25% of adult patients who received 0.15 mg/kg Mivacron over 5 to 15 seconds. When present, flushing typically began within 1 to 2 minutes after the dose of Mivacron and lasted for 3 to 5 minutes. Of 105 patients who experienced flushing after 0.15 mg/kg Mivacron, two patients also experienced mild hypotension that was not treated, and one patient experienced moderate wheezing that was successfully treated.

Overall, hypotension was infrequently reported as an adverse experience in the clinical trials of Mivacron. One of 332 (0.3%) healthy adults who received 0.15 mg/kg Mivacron over 5 to 15 seconds and none of 37 cardiac surgery patients who received 0.15 mg/kg Mivacron over 60 seconds were treated for a decrease in blood pressure in association with the administration of Mivacron. One to two percent of healthy adults given greater than or equal to 0.2 mg/kg Mivacron over 5 to 15 seconds, 2% to 3% of healthy adults given 0.2 mg/kg over 30 seconds, none of 100 healthy adults given 0.25 mg/kg as a divided dose (0.15 mg/kg followed in 30 seconds by 0.1 mg/kg), and 2% to 4% of cardiac surgery patients given greater than or equal to 0.2 mg/kg over 60 seconds were treated for a decrease in blood pressure. None of the 63 children who received the recommended dose of 0.2 mg/kg Mivacron was treated for a decrease in blood pressure in association with the administration of Mivacron.

The following adverse experiences were reported in patients administered Mivacron (all events judged by investigators during the clinical trials to have a possible causal relationship):

Incidence Greater Than 1%

Cardiovascular

Flushing (16%)

Incidence Less Than 1%

Cardiovascular

Hypotension, tachycardia, bradycardia, cardiac arrhythmia, phlebitis

Respiratory

Bronchospasm, wheezing, hypoxemia

Dermatological

Rash, urticaria, erythema, injection site reaction

Nonspecific

Prolonged drug effect

Neurologic

Dizziness

Musculoskeletal

Muscle spasms

Observed in Clinical Practice

Based on initial clinical practice experience in patients who received Mivacron, spontaneously reported adverse events are uncommon. Some of these events occurred at recommended doses and required treatment.

Anaphylaxis/Anaphylactoid Reactions: From post-marketing surveillance, Mivacron has been associated with reports of anaphylactic/anaphylactoid reactions which in some cases have been life-threatening and fatal. Because these reactions were reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency (see WARNINGS and PRECAUTIONS ). In some of these reports, sensitivity to Mivacron was confirmed using skin test procedures.

Other adverse reaction data from clinical practice are insufficient to establish a causal relationship or to support an estimate of their incidence. These adverse events include:

Musculoskeletal

Diminished drug effect, prolonged drug effect

Cardiovascular

Hypotension (rarely severe), flushing

Respiratory

Bronchospasm

Integumentary

Rash

OVERDOSAGE

Overdosage with neuromuscular blocking agents may result in neuromuscular block beyond the time needed for surgery and anesthesia. The primary treatment is maintenance of a patent airway and controlled ventilation until recovery of normal neuromuscular function is assured. Once evidence of recovery from neuromuscular block is observed, further recovery may be facilitated by administration of an anticholinesterase agent in conjunction with an appropriate anticholinergic agent. Overdosage may increase the risk of hemodynamic side effects, especially decreases in blood pressure. If needed, cardiovascular support may be provided by proper positioning of the patient, fluid administration, and/or vasopressor agent administration.

Antagonism of Neuromuscular Block

Antagonists (such as neostigmine) should not be administered when complete neuromuscular block is evident or suspected. The use of a peripheral nerve stimulator to evaluate recovery and antagonism of neuromuscular block is recommended.

Administration of 0.03 to 0.064 mg/kg neostigmine or 0.5 mg/kg edrophonium at approximately 10% recovery from neuromuscular block (range: 1 to 15) produced 95% recovery of the muscle twitch response and a T4/T1 ratio greater than or equal to 75% in about 10 minutes. The times from 25% recovery of the muscle twitch response to T4/T1 ratio greater than or equal to 75% following these doses of antagonists averaged about 7 to 9 minutes. In comparison, average times for spontaneous recovery from 25% to T4/T1 greater than or equal to 75% were 12 to 13 minutes.

Patients administered antagonists should be evaluated for adequate clinical evidence of antagonism, e.g., 5-second head lift and grip strength. Ventilation must be supported until no longer required.

Antagonism may be delayed in the presence of debilitation, carcinomatosis, and the concomitant use of certain broad spectrum antibiotics, or anesthetic agents and other drugs which enhance neuromuscular block or separately cause respiratory depression (see PRECAUTIONS - Drug Interactions ). Under such circumstances the management is the same as that of prolonged neuromuscular block (see OVERDOSAGE ).

DOSAGE AND ADMINISTRATION

Mivacron SHOULD ONLY BE ADMINISTERED INTRAVENOUSLY.

The dosage information provided below is intended as a guide only. Doses of Mivacron should be individualized. Factors that may warrant dosage adjustment include but may not be limited to: the presence of significant kidney, liver, or cardiovascular disease, obesity (patients weighing greater than or equal to 30% more than ideal body weight for height), asthma, reduction in plasma cholinesterase activity, and the presence of inhalational anesthetic agents.

When using Mivacron or other neuromuscular blocking agents to facilitate tracheal intubation, it is important to recognize that the most important factors affecting intubation are the depth of general anesthesia and the level of neuromuscular block. Satisfactory intubating conditions can usually be achieved before complete neuromuscular block is attained if there is adequate anesthesia.

The use of a peripheral nerve stimulator will permit the most advantageous use of Mivacron, minimize the possibility of overdosage or underdosage, and assist in the evaluation of recovery. When using a stimulator to monitor onset of neuromuscular block, clinical studies have shown that all four twitches of the train-of-four response may be present, with little or no fade, at the times recommended for intubation. Therefore, as with other neuromuscular blocking agents, it is important to use other criteria, such as clinical evaluation of the status of relaxation of jaw muscles and vocal cords, in conjunction with peripheral muscle twitch monitoring, to guide the appropriate time of intubation.

The onset of conditions suitable for tracheal intubation occurs earlier after a conventional intubating dose of succinylcholine than after recommended doses of Mivacron.

Adults

Initial Doses

Doses of 0.15 mg/kg administered over 5 to 15 seconds, 0.2 mg/kg administered over 30 seconds, or 0.25 mg/kg administered in divided doses (0.15 mg/kg followed in 30 seconds by 0.1 mg/kg) are recommended for facilitation of tracheal intubation for most patients.

Dosing Paradigm* Anesthetic Induction

Technique Studied

Time to Generally Good-to-

Excellent Intubating Conditions

0.15 mg/kg, intravenous (over 5 to 15 sec) Thiopental/opioid/N2O/O2 or propofol/opioid 2.5 to 3 min after completion of dose
0.2 mg/kg, intravenous (over 30 sec) Thiopental/opioid/N2O/O2 or propofol/opioid 2 to 2.5 min after completion of dose
0.25 mg/kg, intravenous (0.15 mg/kg followed in 30 sec by 0.1 mg/kg) Propofol/opioid 1.5 to 2 min after completion of 0.15 mg/kg dose
* Dosing instituted after induction of adequate general anesthesia.
The purpose of slowed or divided dosing of Mivacron at doses above 0.15 mg/kg is to minimize the transient decreases in blood pressure observed in some patients given these doses over 5 to 15 seconds (see CLINICAL PHARMACOLOGY, PRECAUTIONS , and ADVERSE REACTIONS ). The quality of intubation conditions does not significantly differ for the times and doses of Mivacron recommended in Table 7, but the onset of suitable intubation conditions may be reached earlier with higher doses. The choice of a particular dose and regimen should be based on individual circumstances and patient requirements (see CLINICAL PHARMACOLOGY - Individualization of Dosages ).

In patients with clinically significant cardiovascular disease and in patients with any history suggesting a greater sensitivity to the release of histamine or other mediators (e.g., asthma), the dose of Mivacron should be 0.15 mg/kg or less, administered over 60 seconds (see PRECAUTIONS ). No data are available on the use of doses of Mivacron above 0.15 mg/kg in patients with clinically significant kidney or liver disease.

Clinically effective neuromuscular block may be expected to last for 15 to 20 minutes (range: 9 to 38 minutes) and spontaneous recovery may be expected to be 95% complete in 25 to 30 minutes (range: 16 to 41 minutes) following 0.15 mg/kg Mivacron administered to patients receiving opioid/nitrous oxide/oxygen anesthesia. The expected duration of clinically effective block and time to 95% spontaneous recovery following 0.2 mg/kg Mivacron are approximately 20 and 30 minutes, respectively, and following 0.25 mg/kg Mivacron are approximately 25 and 35 minutes. Initiation of maintenance dosing during opioid/nitrous oxide/oxygen anesthesia is generally required approximately 15, 20 and 25 minutes following initial doses of 0.15 mg/kg, 0.2 mg/kg, and 0.25 mg/kg Mivacron, respectively. Maintenance doses of 0.1 mg/kg each provide approximately 15 minutes of additional clinically effective block. For shorter or longer durations of action, smaller or larger maintenance doses may be administered.

The neuromuscular blocking action of Mivacron is potentiated by isoflurane or enflurane anesthesia. Recommended initial doses of Mivacron may be used to facilitate tracheal intubation prior to the administration of these agents; however, if Mivacron is first administered after establishment of stable-state isoflurane or enflurane anesthesia (administered with nitrous oxide/oxygen to achieve 1.25 MAC), the initial dose of Mivacron may be reduced by as much as 25%. Greater reductions in the dose of Mivacron may be required with higher concentrations of enflurane or isoflurane. With halothane, which has only a minimal potentiating effect on Mivacron, a smaller dosage reduction may be considered.

Continuous Infusion

Continuous infusion of Mivacron may be used to maintain neuromuscular block. Upon early evidence of spontaneous recovery from an initial dose, an initial infusion rate of 9 to 10 mcg/kg/min is recommended. If continuous infusion is initiated simultaneously with the administration of an initial dose, a lower initial infusion rate should be used (e.g., 4 mcg/kg/min). In either case, the initial infusion rate should be adjusted according to the response to peripheral nerve stimulation and to clinical criteria. On average, an infusion rate of 5 to 7 mcg/kg/min (range: 1 to 15 mcg/kg/min) may be expected to maintain neuromuscular block within the range of 89% to 99% for extended periods in adults receiving opioid/nitrous oxide/oxygen anesthesia. In some patients, particularly those with higher infusion requirements (greater than 8 mcg/kg/min) during the first 30 minutes, the infusion rate required to maintain 89% to 99% T1 suppression may decrease gradually (by greater than or equal to 30%) with time over a 4- to 6-hour period of infusion (see CLINICAL PHARMACOLOGY - Pharmacodynamics ). Reduction of the infusion rate by up to 35% to 40% should be considered when Mivacron is administered during stable-state conditions of isoflurane or enflurane anesthesia (administered with nitrous oxide/oxygen to achieve 1.25 MAC). Greater reductions in the infusion rate of Mivacron may be required with greater concentrations of enflurane or isoflurane. With halothane, smaller reductions in infusion rate may be required.

Children

Initial Doses

Dosage requirements for Mivacron on a mg/kg basis are higher in children than in adults. Onset and recovery of neuromuscular block occur more rapidly in children than in adults.

The recommended dose of Mivacron for facilitating tracheal intubation in children 2 to 12 years of age is 0.2 mg/kg administered over 5 to 15 seconds. When administered during stable opioid/nitrous oxide/oxygen anesthesia, 0.2 mg/kg of Mivacron produces maximum neuromuscular block in an average of 1.9 minutes (range: 1.3 to 3.3 minutes) and clinically effective block for 10 minutes (range: 6 to 15 minutes). Maintenance doses are generally required more frequently in children than in adults. Administration of doses of Mivacron above the recommended range (greater than 0.2 mg/kg) is associated with transient decreases in MAP in some children (see CLINICAL PHARMACOLOGY - Hemodynamics ). Mivacron has not been studied in pediatric patients below the age of 2 years.

Continuous Infusion

Children require higher infusion rates of Mivacron than adults. During opioid/nitrous oxide/oxygen anesthesia, the infusion rate required to maintain 89% to 99% neuromuscular block averages 14 mcg/kg/min (range: 5 to 31 mcg/kg/min). The principles for infusion of Mivacron in adults are also applicable to children.

Infusion Rate Tables

For adults and children the amount of infusion solution required per hour depends upon the clinical requirements of the patient, the concentration of Mivacron in the infusion solution, and the patient's weight. The contribution of the infusion solution to the fluid requirements of the patient must be considered. Table 8 provides guidelines for delivery in mL/hr (equivalent to microdrops/min when 60 microdrops = 1 mL) of Mivacron Injection (2 mg/mL).
