Erectile Dysfunction and Hypertension

All triplet PDE5 inhibitors are contraindicated in patients taking organic nitrates (including short-acting or long-acting nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, amyl nitrate and others). Organic nitrates addition cyclic GMP human activity whereas PDE5 inhibitors lessening cyclic GMP collapse. Therefore, there is a synergistic drop in BP when PDE5 inhibitors are given with organic nitrates that results in symptomatic hypotension in some patients.

If a semantic role has taken a PDE5 inhibitor and then develops thorax pain, when is it safe to re-introduce nitroglycerin? The example Habitant Body of Cardiology/American Organs Organization guidelines suggested that for viagra, 5-6 half-lines or 24 h pass before nitrates are given to a semantic role who has taken sildenafil (half-life is about 4 h). Studies comparing nitrate fundamental interaction between sildenafil versus tadalafil 20mg confirmed that there was a lack of action between sildenafil and nitrate 24 h after viagra was administered. There is an unpublished musing suggesting a lack of action with nitroglycerin at 24 h after vardenafil, consistent with its 4 h half-life. Finally, one immersion suggests an fundamental interaction between tadalafil (half-life 17.5 h) and nitroglycerin that is gift at 24 h after a dose of tadalafil but that is gone by 48 h and beyond.

Thus, although all figure PDE5 inhibitors are contraindicated in patients receiving either short-acting or long-acting nitrates, should a semantic role with ED take a PDE5 inhibitor and then develop heart disease, nitroglycerin should not be reintroduced until after 24 h for sildenafil or vardenafil and after 48 h for cialis. Of form, other antianginal and anti-ischemic therapies may be used - such as beta blockers, calcium blockers, aspirin, morphine, statins and percutaneous coronary locating. None of these are contraindicated with PDE5 inhibitors.
