Drug Interactions
CYP3A4 (major route) & 2C9 (minor route) inhibitors may reduce sildenafil clearance & inducers may increase sildenafil clearance. Decreased exposure w/ CYP3A4 inducers eg, bosentan, carbamazepine, phenytoin, phenobarb, St. John's wort, rifampicin. Increased AUC w/ CYP3A4 inhibitors eg, saquinavir, erythromycin, clarithromycin, telithromycin, nefazodone. Increased exposure w/ β-blockers. Concomitant use w/ grapefruit juice is not recommended. Potential serious interaction w/ nicorandil. Potentiate the hypotensive effects of nitrates. May lead to symptomatic hypotension w/ α-blockers. Increased AUC of bosentan.
