Hypersensitivity reactions have been reported, including rash and urticaria [see Adverse Reactions (6.1)].Metabolism and Excretion: Sildenafil is cleared predominantly by the CYP3A4 (major route) and CYP2C9 (minor route) hepatic microsomal isoenzymes. The major circulating metabolite results from N-desmethylation of sildenafil, and is itself further metabolized. This metabolite has a PDE selectivity profile similar to sildenafil and an in vitro potency for PDE5 approximately 50% of the parent drug. Plasma concentrations of this metabolite are approximately 40% of those seen for sildenafil, so that the metabolite accounts for about 20% of sildenafil's pharmacologic effects. heartburn

Renal ImpairmentThird, we did not have the information on other PDE5A inhibitors because neither vardenafil nor tadalafil had been approved by the US Food and Drug Administration in 2000. The observed association between sildenafil use and melanoma might be partly attributed to the later use of vardenafil and tadalafil among recent sildenafil users. A longer clearance time of other PDE5A inhibitors could have augmented the observed HR for sildenafil.12 However, this would not materially jeopardize our study implications for PDE5A inhibitors.
