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.

The acetylcholinesterase (AchE) inhibitory effect of a muscle relaxant 2 beta,16 beta-bis-(4'-dimethyl-1'-piperazino)-3 alpha,17 beta-diacetoxy-5 alpha-androstane dibromide (pipecurium bromide, RGH-1106, Arduan), was studied in vitro. The inhibition of AchE activity of human red blood cells, expressed as pI50, was 3.99, whereas that of serum cholinesterase (ChE) was 4.33. The AchE inhibitor action was reversible. The inhibition was not influenced by the combined administration of promethazine or atropine. The combined effect of pipecurium bromide and of some other diamino-azasteroid agent proved to be additive. Pipecurium bromide showed mixed-type inhibitory effect both on AchE and ChE.
