Abstract
The invention refers to new pharmaceutical compositions with both excellent vasodilatory activity on the coronary arteries and time of action. These are 2,6-dimethyl-4-(3- nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylic acid 3- (benzylpyrrolidine-3-yl) ester 5-methylester's A- diastereoisomer, the hydrochloride of which has a melting point of 200 - 206 degree C (breaks up); the A-diastereoisomer's dextrorotatory isomer and pharmaceutically acceptable acid addition salts of these compounds. Pharmaceutical compounds according to the invention may be separated from mixtures containing other isomers with various methods, including chromatograph and fractional crystallization.
