Vecuronium and d-tubocurarine combination: potentiation of effect. 1985

R K Mirakhur, and F M Gibson, and C J Ferres

To evaluate possible potentiation of neuromuscular blocking effect of a combination of vecuronium and d-tubocurarine, cumulative dose-response curves were constructed to compare the potency of this combination with vecuronium and d-tubocurarine given alone. Ten patients each were given incremental injections of 80 micrograms/kg d-tubocurarine or 5 micrograms/kg vecuronium plus 40 micrograms/kg d-tubocurarine, the data for incremental administration of 10 micrograms/kg vecuronium being used from our previously published study (7). The results showed the combination of vecuronium plus d-tubocurarine to be significantly more potent (P less than 0.05) than would be expected from a simple additive effect of the individual drugs given alone. The ED95 doses of d-tubocurarine and vecuronium were 530 micrograms/kg and 57 micrograms/kg, respectively, when administered alone, but when administered together, the ED95 doses were 160 and 20 micrograms/kg, respectively.

UI	MeSH Term	Description	Entries
D009466	Neuromuscular Blocking Agents	Drugs that interrupt transmission of nerve impulses at the skeletal neuromuscular junction. They can be of two types, competitive, stabilizing blockers (NEUROMUSCULAR NONDEPOLARIZING AGENTS) or noncompetitive, depolarizing agents (NEUROMUSCULAR DEPOLARIZING AGENTS). Both prevent acetylcholine from triggering the muscle contraction and they are used as anesthesia adjuvants, as relaxants during electroshock, in convulsive states, etc.	Neuromuscular Blocker,Neuromuscular Blocking Agent,Neuromuscular Blockers,Agent, Neuromuscular Blocking,Agents, Neuromuscular Blocking,Blocker, Neuromuscular,Blockers, Neuromuscular,Blocking Agent, Neuromuscular,Blocking Agents, Neuromuscular
D010197	Pancuronium	A bis-quaternary steroid that is a competitive nicotinic antagonist. As a neuromuscular blocking agent it is more potent than CURARE but has less effect on the circulatory system and on histamine release.

D014673	Vecuronium Bromide	Monoquaternary homolog of PANCURONIUM. A non-depolarizing neuromuscular blocking agent with shorter duration of action than pancuronium. Its lack of significant cardiovascular effects and lack of dependence on good kidney function for elimination as well as its short duration of action and easy reversibility provide advantages over, or alternatives to, other established neuromuscular blocking agents.
