Uses

Nor Q IV Injection 10 mg/vial is indicated as an adjunct to general anaesthesia to facilitate endotracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation.

Dosage

Nor Q IV Injection 10 mg/vial dosage

The recommended initial dose of Vecuronium is 0.08 to 0.10 mg/kg body weight given as an I.V. bolus injection. This dose can be expected to produce good or excellent non-emergency intubation conditions in 2.5 to 3.0 minutes after injection. In caesarean section and neonatal surgery the dose should not exceed 0.1 mg/kg. Like other neuromuscular blocking agents, Nor Q IV Injection 10 mg/vial should only be administered by, or under supervision of, experienced clinicians who are familiar with the action and use of these agents; the dosage of Nor Q IV Injection 10 mg/vial should be individualized in each patient. Consequently, adjustments with Nor Q IV Injection 10 mg/vial should be made by administering smaller maintenance doses at less frequent intervals or by using lower infusion rates of Nor Q IV Injection 10 mg/vial during long lasting procedures (longer than 1 hour) under inhalational anaesthesia. In adult patients the following dosage recommendations may serve as a general guideline for tracheal intubation and muscle relaxation for short to long lasting surgical procedures. Tracheal intubation: The standard intubating dose during routine anaesthesia is 0.08 to 0.1 mg Nor Q IV Injection 10 mg/vial per kg body weight, after which adequate intubation conditions are established within 90 to 120 seconds in nearly all patients. Dosages of Nor Q IV Injection 10 mg/vial for surgical: procedures after intubation with suxamethonium: If suxamethonium is used for intubation, the administration of Vecuronium should be delayed until the patient has clinically recovered from the neuromuscular block induced by suxamethonium. Recommended dose is 0.03 to 0.05 mg Nor Q IV Injection 10 mg/vial per kg body weight. Maintenance dosing: The recommended maintenance dose is 0.02 to 0.03 mg Nor Q IV Injection 10 mg/vial per kg body weight. These maintenance doses should best be given when twitch height has recovered to 25% of control twitch height. Dose requirements for administration of Nor Q IV Injection 10 mg/vial by continuous infusion: If Vecuronium is administered by continuous infusion, it is recommended to give a loading dose (0.08 to 0.1 mg Nor Q IV Injection 10 mg/vial per kg body weight) first and, when neuromuscular block starts to recover, to start administration of Vecuronium by infusion. The infusion rate should be adjusted to maintain twitch response at 10% of control twitch height or to maintain 1 to 2 responses to train of four stimulation. In adults, the infusion rate required to maintain neuromuscular block at this level, ranges from 0.8 to 1.4 µg Nor Q IV Injection 10 mg/vial/kg/min. Repeat monitoring of neuromuscular block is recommended since infusion rate requirements vary from patient to patient and with the anaesthetic method used. Dosing in elderly patients: The same intubation and maintenance doses as for younger adults (0.08-0.1 mg/kg and 0.02-0.03 mg/kg, respectively) can be used. The onset time in elderly is similar to younger adults. Dosing in paediatric patients: Neonate (up to 4 weeks) and children up to 4 months: initial test dose 0.01 to 0.02 mg/kg then incremental doses until 90% to 95% depression of twitch response is achieved is recommended. In neonatal surgery the dose should not exceed 0.1 mg/kg. Children over 5 months to 10 years: 0.08-0.1 mg/kg (children under 12 months, onset more rapid and high intubation dose may not be required); maintenance 0.02-0.03 mg/kg adjusted according to response. Since the duration of action is shorter in children, maintenance doses are required more frequently. Dosing in overweight and obese patients: When used in overweight or obese patients doses should be reduced taking into account an ideal body weight. Initial doses ranging from 0.15 mg up to 0.30 mg Nor Q IV Injection 10 mg/vial per kg body weight have been administered during surgery both under halothane and neurolept anaesthesia. Nor Q IV Injection 10 mg/vial should be administered following reconstitution. VencurTM is administered intravenously either as a bolus injection or as a continuous infusion. Reconstitution: Alternatively, in order to obtain a solution with a lower concentration, Nor Q IV Injection 10 mg/vial 10 mg may be reconstituted with a volume up to 10 ml respectively of the following infusion fluids: 5% glucose IV solution 0.9% sodium chloride IV solution Lactated Ringer's solution Lactated Ringer's and 5% glucose IV solution Glucose 5% and 0.9% sodium chloride IV solution

Side Effects

Nor Q IV Injection 10 mg/vial is a non-depolarising muscle relaxants, has an intermediate duration of action. It does not generally produce histamine release and lacks cardiovascular effects. The common side effects of non-depolarising muscle relaxants are skin flushing, hypotension, tachycardia, bronchospasm and very rarely, anaphylactoid reactions. Acute myopathy has also been reported after prolonged use in intensive care.

Precaution

Allergic cross-reactivity between neuromuscular blocking agents has been reported; caution is advised in cases of hypersensitivity to these drugs. Their activity is prolonged in patients with myasthenia gravis and in hypothermia, therefore lower doses are required. Non-depolarising muscle relaxants should be used with great care in those with other neuromuscular disorders and those with fluid and electrolyte disturbances, as response is unpredictable. Resistance may develop in patients with burns who may require increased doses; low plasma cholinesterase activity in these patients requires dose titration for mivacurium. General: Vecuronium should be administered in carefully adjusted dosage by or under the supervision of experienced clinicians who are familiar with its actions and the possible complications that might occur following its use. The drug should not be administered unless facilities for intubation, artificial respiration, oxygen therapy, and reversal agents are immediately available. The clinician must be prepared to assist or control respiration. A peripheral nerve stimulator should be employed to monitor drug response, need for additional relaxant, and adequacy of spontaneous recovery or anticholinesterase antagonism.Intensive Care Unit: To reduce the possibility of prolonged neuromuscular blockade and other complications that might occur following long-term use in the ICU, Vecuronium or any other neuromuscular blocking agent should be administered in carefully adjusted doses by or under the supervision of experienced clinicians who are familiar with its actions and with appropriate peripheral nerve stimulator muscle monitoring techniques.Neuromuscular Disease: In patients who are known to have myasthenia gravis or the myasthenic syndrome, small doses of Vecuronium may have profound effects. In such patients, a peripheral nerve stimulator and use of a small test dose may be of particular value in assessing and monitoring dosage requirements.

Interaction

Succinylcholine: Prior administration of succinylcholine may enhance the neuromuscular blocking effect of Vecuronium and its duration of action. If succinylcholine is used before Vecuronium, the administration of Vecuronium should be delayed until the succinylcholine effect shows signs of wearing off. With succinylcholine as the intubating agent, initial doses of 0.04 to 0.06 mg/kg of vecuronium may be administered to produce complete neuromuscular block with clinical duration of action of 25 to 30 minutes. Other nondepolarizing neuromuscular blocking agents (pancuronium, d-tubocurarine, metocurine and gallamine) act in the same fashion as does Vecuronium; therefore, these drugs and Vecuronium may manifest an additive effect when used together. Inhalation Anesthetics: Use of volatile inhalational anesthetics such as enflurane, isoflurane, and halothane with Vecuronium will enhance neuromuscular blockade. Antibiotics: Parenteral/intraperitoneal administration of high doses of certain antibiotics may intensify or produce a neuromuscular block on their own. The following antibiotics have been associated with various degrees of paralysis: aminoglycosides (such as neomycin, streptomycin, kanamycin, gentamicin, and dihydrostreptomycin); tetracyclines; bacitracin; polymyxin B; colistin; and sodium colistimethate. If these or other newly introduced antibiotics are used in conjunction with vecuronium during surgery, unexpected prolongation of neuromuscular block should be considered a possibility. Other: Experience concerning injection of quinidine during recovery from use of other muscle relaxants suggests that recurrent paralysis may occur. This possibility must also be considered for vecuronium. Vecuronium induced neuromuscular blockade has been counteracted by alkalosis and enhanced by acidosis in experimental animals (cat). Electrolyte imbalance and diseases which lead to electrolyte imbalance, such as adrenal cortical insufficiency, have been shown to alter neuromuscular blockade. Depending on the nature of the imbalance, either enhancement or inhibition may be expected. Magnesium salts, administered for the management of toxemia of pregnancy, may enhance neuromuscular blockade.

Pregnancy & Breastfeeding use

There are insufficient data on the use of Vecuronium during animal or human Pregnancy to assess potential harm to the foetus. Vecuronium should be given to a pregnant woman only when the attending physician decides that the benefits outweigh the risks. There are no human data on the use of Vecuronium during lactation. Vecuronium should be given to lactating women only when the attending physician decides that the benefits outweigh the risks. Caesarean section: Studies with Vecuronium, administered in doses up to 0.1 mg/kg, have shown its safety for use in caesarean section. In caesarean section the dose should not exceed 0.1 mg/kg. In several clinical studies Vecuronium did not affect Apgar score, foetal muscle tonus or cardio respiratory adaptation. From umbilical cord blood sampling it is apparent that only very little placental transfer of vecuronium occurs which did not lead to the observation of any clinical adverse effect in the newborn.

Contraindication

Hypersensitivity to vecuronium or the bromide ion or any of the excipients of vecuronium.

Acute Overdose

In the event of overdosage and prolonged neuromuscular block, the patient should continue to receive ventilatory support and sedation. Upon start of spontaneous recovery an acetylcholinesterase inhibitor (e.g. neostigmine, edrophonium, pyridostigmine) should be administered in adequate doses. When administration of an acetylcholinesterase-inhibiting agent fails to reverse the neuromuscular effects of Vecuronium, ventilation must be continued until spontaneous breathing is restored. Repeated dosage of an acetylcholinesterase inhibitor can be dangerous.

Storage Condition

Store in a cool and dry place. Protect from light. Keep out of the reach of children.
