Muscle Relaxation Rocuronium Bromide Injection Adjunct General Anesthesia

 

 

Product : Rocuronium Bromide Injection

Specification : 5ml:50mg, 2.5ml:25mg

Standard : BP, USP

Packing : 10vials/box

 

Description :

Rocuronium (rapid onset-curonium) is a desacetoxy analogue of vecuronium with a more rapid onset of action. It is an aminosteroid non-depolarizing neuromuscular blocker or muscle relaxant used in modern anaesthesia, to facilitate endotracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation.

 

Indication

For inpatients and outpatients as an adjunct to general anesthesia to facilitate both rapid sequence and routine tracheal intubation, and to provide skeletal muscle relaxation during surgery or mechanical ventilation.

 

Pharmacodynamics

Neuromuscular blocking agents are drugs that cause skeletal muscle relaxation primarily by causing a decreased response to the neurotransmitter acetylcholine (ACh) at the myoneural (neuromuscular) junction of skeletal muscle. At that site, ACh normally produces electrical depolarization of the postjunctional membrane of motor end-plate, which leads to conduction of muscle action potential and subsequently induces skeletal muscle contraction. Neuromuscular agents are classified as depolarizing or nondepolarizing. Rocuronium is a nondepolarizing neuromuscular blocking agent with a rapid to intermediate onset depending on dose and intermediate duration. Rocuronium, like vecuronium is longer acting in infants than in children. However, unlike vecuronium, rocuronium retains the characteristics of an intermediate-acting NMBD in infants.

 

Mechanism of action

Rocuronium acts by competing for cholinergic receptors at the motor end-plate. This action is antagonized by acetylcholinesterase inhibitors, such as neostigmine and edrophonium. Rocuronium acts by competitively binding to nicotinic cholinergic receptors. The binding of vecuronium decreases the opportunity for acetylcholine to bind to the nicotinic receptor at the postjunctional membrane of the myoneural junction. As a result, depolarization is prevented, calcium ions are not released and muscle contraction does not occur. Evidence also suggests that nondepolarizing agents can affect ACh release. It has been hypothesized that nondepolarzing agents bind to postjunctional ("curare") receptors and may therefore interfere with the sodium and potassium flux, which is responsible for depolarization and repolarization of the membranes involved in muscle contraction.
