  • Patent number: 4499100
    Abstract: Novel compounds of the general formula: ##STR1## and the pharmaceutically acceptable acid addition salts thereof, wherein: R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are each independently hydrogen, lower alkyl, lower alkoxy, trifluoromethyl, halo, lower alkylthio, lower alkyl sulfinyl or lower alkyl sulfonyl;R.sup.5 is hydrogen or lower alkyl;m is 0 or 1;W is alkylene, --CH.dbd.CH--, --O--, or --N(R.sup.6)--, where R.sup.6 is lower alkyl or hydrogen;n is 0 or 1; andQ is lower alkyl, cycloalkyl or optionally substituted phenyl.These compounds combine .beta.-blockade and calcium entry blockade properties in the same compound and therefore are useful in therapy in the treatment of cardiovascular diseases, including myocardial infarction, hypertension, arrhythmia and variant and exercise induced angina. The compounds are also useful in immunosuppressant therapy for immune diseases, such as rheumatoid arthritis.
