Enhanced hypotensive effect w/ vasodilators and other hypotensive drugs. Reduced efficacy (oral/buccal preparations) w/ drugs that cause dry mouth (e.g. TCAs, other antimuscarinics). Increased vasodilatory effect w/ acetylcysteine. May reduce the thrombolytic activity of alteplase. May increase the bioavailability of dihydroergotamine which may lead to coronary vasoconstriction.Potentially Fatal: Potentiation of hypotensive effect w/ PDE5 inhibitors (e.g. sildenafil, tadalafil, vardenafil), riociguat and other organic nitrates w/ nitric oxide (NO) donors. May reduce the anticoagulant effect of heparin.
