Vasodilators - StatPearls - NCBI Bookshelf The one drug in this group, hydralazine, does not fit neatly into the other mechanistic classes, in part, because its mechanism of action is not entirely clear and it appears to have multiple, direct effects on the vascular smooth muscle.First, hydralazine causes smooth muscle hyperpolarization quite likely through the opening of K +-channels. An Underused Vasodilator for Resistant or Severe Hypertension - Medscape Converted to NO which stimulates cGMP production.Acts as a smooth muscle relaxant and venodilator (why NTG is more of a venodilator than a vasodilator is not known).Note that the process of NO formation is dependent on availability of sulfhydryl (SH) groups and thus tolerance can develop.
