This invention relates to novel mono- and bisquaternary ammonium derivatives of 5a-androstanes having the formula:
wherein:
R, = H or alkyl (1-4 C);
R2 and R3 each are alkyl (1-4 C) or form together with the N-atom a piperidino, pyrrolidino or morpholino group;
R4 = 0 or H(βOR5) and
R5 = H or acyl derived from an organic carboxylic acid having 1-18, preferably 1-6 carbon atoms; the quaternarising group being a saturated or unsaturated aliphatic hydrocarbon group having 1-4 carbon atoms the anion being halide; and acid addition salts of the monoquaternary compounds; and to pharmaceutical preparations containing one or more of said androstane compounds as active constituent.
The compounds according to the invention are non-depolarising neuromuscular blocking agents having very quick onset and recovery characteristics, a short duration of action and a favourable dissociation between muscle blocking and vagal blocking effects.
