[Interaction between antihypertensive agents and psychotropic drugs (author's transl)].

The present review paper is dealing with the interaction between antihypertensive agents and various psychotropic drugs. Various psychotropic drugs enhance certain-side-effects of the antihypertensive substances, like sedation, extrapyramidal disorders and orthostatic hypotension. On the other hand, the blood-pressure lowering effect of clonidine, guanethidine and related drugs, and possibly also that of alpha-methy-dopa is reduced by phenothiazine-neuroleptics and tricyclic antidepressants (thymoleptics), but not by benzodiazepine tranquilizers or by butyrophenone-like neuroleptics. The pharmacological background and the clinical relevance of these interaction phenomena are discussed.
