On some properties of a new steroid curare-like compound pipecurium bromide.
In experiments on cats it has been shown that 2 beta, 16 beta-bis (4'-dimethyl-1'-piperazino)-3 alpha, 17 beta-diacetoxy-5 alpha-androstane dibromide (pipecurium bromide, RGH-1106, Arduan), is a non-depolarizing muscular blocker. The order of myorelaxation evoked by this agent is characteristic: first the chewing and limb muscles, then abdominal muscles and diaphragm and at the end intercostal muscles are relaxed. Pipercurium bromide has no cardiotropic, atropine-like, or ganglion-blocking activity. It fails to influence the coronary blood-supply or myocardial oxygen consumption. No acetylcholinesterase inhibiting action of the compound was seen. It does not affect the central nervous system.
