Abstract
Abstract A group of pyridine compounds useful in the treatment of disorders and diseases of the cardiovascular system and/or in the treatment of superficial and deep allergic phenomena is described. These compounds are piperidine compounds linked by the nitrogen atom to a pyridine ring through the intermediary of a lower-alkylene radical. The piperidine ring is further substituted by an acylamino residue.
