摘要:
Derivatives of 3-pyrrolidinopropiophenone of the formula (I) wherein R is an ethyl-, propyl-, isopropyl-, butyl-, isobutylgroup or a cycloalkyl-group having 5 to 7 carbon atoms, and the pharmaceutically acceptable acid addition salts thereof, exhibit a potent activity on muscle relaxation. Furtheron a process for the preparation of these compounds is disclosed.
摘要:
1-(3,4,5-Trimethoxycinnamoyl)-4-aminocarbonylethyl-substituted piperazine derivatives represented by general formula (I): wherein R is a straight- or branched-chain alkyl group having 1 to 6 carbon atoms or a cycloalkyl group having 5 to 7 carbon atoms, and pharmaceutically acceptable acid addition salts thereof are disclosed. The 1-(3,4,5-trimethoxycinnamoyl)-4-aminocarbonylethyl-substituted piperazine derivatives are useful as vasodilator agents.
摘要:
A pharmceutical composition capable of being disintegrated in an acidic environment, which comprises calcium polycarbophil and 1 to 80 % by weight of a cellulose derivative such as carboxymethylcellulose or low substituted hydroxypropylcellulose based on the calcium polycarbophil. The pharmaceutical composition in a form of a tablet, a capsule, or granules is useful as a bulk-forming laxative or an antidiarrheic agent since it can be disintegrated readily in the stomach and form a complete dispersion of polycarbophil in the digestive tract.
