Category: | Neuromuscular Nondepolarizing Agents, Skeletal Muscle Relaxants |

Pharmacology: |
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...

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...

Absorption: | Poorly absorbed from the GI tract. |
Protein binding: | Approximately 30% bound to human plasma proteins. |
Biotransformation: | Rocuronium is metabolized to a less active metabolite, 17-desacetyl-rocuronium, and is eliminated primarily by the liver. |
Route of elimination: | Studies of distribution, metabolism, and excretion in cats and dogs indicate that rocuronium is eliminated primarily by the liver. |
Half Life: | The rapid distribution half-life is 1-2 minutes and the slower distribution half-life is 14-18 minutes. Renal impairment has no net effect on half-life, however, half-life is almost doubled in patients with impaired liver function. |
Clearance: | 0.25 L/kg/hr [Adults (Ages 27 to 58 years)] 0.21 L/kg/hr [Geriatrics (>=65 yrs)] 0.16 L/kg/hr [Normal ewnal and hepatice function] 0.13 L/kg/hr [Renal transplant patients] 0.13 L/kg/hr [Hepatic dysfunction patients] 0.35 +/- 0.08 L/kg/hr [Pediatric Patients 3 to <12 mos] 0.32 +/- 0.07 L/kg/hr [Pediatric Patients 1 to 3 yrs] 0.44 +/- 0.16 L/kg/hr [Pediatric Patients 3 to 8 yrs] |
Toxicity: | No cases of significant accidental or intentional overdose have been reported. Overdosage with neuromuscular blocking agents may result in neuromuscular block beyond the time needed for surgery and anesthesia. |
Affected organisms: | Humans and other mammals |
