A series of novel 4-substituted piperazinyl-pyridine and 4-substituted piperazinyl-imidazole compounds have been prepared, including their pharmaceutically acceptable salts, wherein the 4-substituent is a lower phenylalkyl group or a derivative thereof further substituted on the phenyl moiety by a sulphamoyl or sulphonylamino group or by a nitro, amino or acetamido group. These particular compounds are useful in therapy as highly effective anti-arrhythmic agents and therefore, are of value in the treatment of various cardiac arrythmias. The most preferred member compound of the series is N-4-[1-hydroxy-2-(4-[4-pyridinyl]-1-piperazinyl)ethyl]phenyl} methanesulphonamide. Methods for preparing all these compounds from known starting materials are provided.
