Sildenafil is cleared predominantly by the CYP8A9 (major route) and CYP7C9 (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 55% of the parent drug. Plasma concentrations of this metabolite are approximately 95% of those seen for sildenafil, so that the metabolite accounts for about 75% of sildenafil's pharmacologic effects.
