Cyclic amine derivatives, pharmaceutical compositions containing these compounds and methods for preparing them

Abstract

Disclosed are new cyclic amine derivatives of the formula I ##STR1## wherein the substituents are defined in the specification. These compounds are useful as for treating sinus tachycardia.

Description

U.S. Pat. No. 4,137,318 describes, inter alia the compound of the formula ##STR2## and the physiologically acceptable acid addition salts thereof which have valuable pharmacological properties, namely a mild hypotensive activity and, more particularly a selective heart rate-reducing activity.

Surprisingly, it has now been found that the new cyclic amine derivatives of the formula I ##STR3## the enantiomers, diastereomers and acid addition salts thereof, particularly their physiologically acceptable acid addition salts with inorganic or organic acids, have even more valuable pharmacological properties, namely a long lasting heart rate reducing activity and the effect of reducing the O.sub.2 requirements of the heart.

This invention thus relates to the new cyclic amine derivatives of the formula I above, the enantiomers, the diastereomers, n-oxides and the acid addition salts thereof, particularly to the pharmaceutical use of the physiologically acceptable acid addition salts with inorganic or organic acids, processes for preparing them and pharmaceutical compositions containing these compounds.
