In patients taking strong CYP inhibitors such as ritonavir, sildenafil exposure is increased.
Adverse Reactions with the Concomitant Use of Ritonavir The concomitant administration of the protease inhibitor ritonavir substantially increases serum concentrations of sildenafil (11-fold increase in AUC).
To decrease the chance of adverse reactions in patients taking ritonavir, the maximum recommended dosage and dosing frequency of SILDENAFIL ORAL FILM is 25 mg once in a 48-hour period [see Dosage and Administration ( 2.2 ), Drug Interactions ( 7.4 ), and Clinical Pharmacology ( 12.3 ) ].
Ritonavir: Do not exceed a maximum single dose of 25 mg in a 48- hour period.
CYP3A4 inhibitors (e.g., ritonavir, ketoconazole, itraconazole, erythromycin) increase SILDENAFIL ORAL FILM exposure.
