SALTS OF ENDO-8-METHYL-8-SYN-ALKYL-8-AZONIABICYCLO-(3.2.1)-OCTANE-3-ALKYLCARBOXYLATES, PROCESS FOR THEIR PREPARATION AND THERAPEUTIC COMPOSITIONS CONTAINING THEM

摘要

The invention relates to new salts of endo-8-methyl-8-syn-alkyl-8-azoniabicyclo-[3.2.1]-octane-3-alkylcarbox ylates, of formula: in which R1 is a linear or branched alkyl radical of 2-5 C atoms, a cycloalkyl radical of 3-6 C atoms, or a phenyl-alkyl radical, R3 and R4, which can be the same or different, are alkyl radicals of 1-6 C atoms, X is a halide ion. The new compounds are potent spasmolytics.
