Sample Use Guides

The influence of a pure afterload reduction on systolic time intervals and various echocardiographic indices was assessed in six healthy volunteers, who underwent a single blind placebo controlled trial of three regimens of intravenous dihydralazine (6.25, 12.5, and 25.0 mg).
Route of Administration: Intravenous
In Vitro Use Guide
Curator's Comment: In mice bone marrow cells, dihydralazine induced a modest but statistically significant increase over controls in the frequency of sister chromatid exchanges, the rank of potencies being in this case dihydralazine greater than endralazine greater than hydralazine. In the Ames reversion test all three drugs behaved as direct-acting mutagens of low potency, whose activity was not influenced by rat liver nor by mouse liver or lung S-9 fractions. Hydralazine and dihydralazine elicited mixed genetic mechanisms of mutations, while endralazine exclusively induced frameshift errors in Salmonella DNA.
