What happens if I overdose?
Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor, which breaks down cyclic GMP and enhances nitric oxide (NO) -mediated smooth muscle relaxation. In erectile dysfunction (ED), this increases blood flow to penile tissue, facilitating an erection. In pulmonary arterial hypertension (PAH), it dilates pulmonary vessels by the same mechanism, reducing pulmonary blood pressure and improving exercise capacity. Sildenafil first gained FDA approval on March 27, 1998. Do not take sildenafil if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and some recreational drugs such as "poppers".
