Dihydralazine is a substrate of the human N-acetyltransferase. Therefore the acetylator phenotype could influence the pharmacodynamic response of dihydralazine and/or side effects of this drug. In this study it could be shown that: among patients with dihydralazine incompatibility slow acetylators preponderated; the risk of early side effects was higher in females than in males; and the ratio of fast/slow acetylators was higher in dihydralazine treated patients than in patients treated with other antihypertensives. Dihydralazine should be given very cautiously to female hypertonic patients that are slow acetylators.
