Indexing Status
Ozanimod has not been studied in patients taking concurrent QT prolonging drugs; however, QT prolonging drugs have been associated with TdP in patients with bradycardia. Pacritinib: (Major) Concomitant use of pacritinib and vardenafil increases the risk of QT/QTc prolongation and torsade de pointes (TdP). Paliperidone: (Major) Concomitant use of vardenafil and paliperodone increases the risk of QT/QTc prolongation and torsade de pointes (TdP).

PDE5 inhibitors, including vardenafil, may potentiate the hypotensive effects of riociguat. Risperidone: (Moderate) Concomitant use of vardenafil and risperidone may increase the risk of QT/QTc prolongation and torsade de pointes (TdP) in some patients. Ritlecitinib: (Major) Do not use vardenafil orally disintegrating tablets with ritlecitinib due to increased vardenafil exposure; do not exceed a single dose of 5 mg per 24-hour period of vardenafil oral tablets. Vardenafil is primarily metabolized by CYP3A; ritlecitinib is a moderate CYP3A inhibitor. Ritonavir: (Major) Do not use vardenafil orally disintegrating tablets with ritonavir due to increased vardenafil exposure; do not exceed a single dose of 2.5 mg per 72-hour period of vardenafil oral tablets.
How is vardenafil supplied (dosage forms)?
Romidepsin: (Moderate) Concomitant use of vardenafil and romidepsin may increase the risk of QT/QTc prolongation and torsade de pointes (TdP) in some patients. Sapropterin: (Moderate) Sapropterin acts as a cofactor in the synthesis of nitric oxide and may cause vasorelaxation. Caution should be exercised when administering sapropterin in combination with drugs that affect nitric oxide-mediated vasorelaxation such as phosphodiesterase inhibitors. When given together these agents may produce an additive reduction in blood pressure. The combination of sapropterin and a phosphodiesterase (PDE5) inhibitor did not significantly reduce blood pressure when administered concomitantly in animal studies. described at 2 times the maximum recommended dose.
What are the differences between vardenafil and tadalafil?
Ribociclib: (Major) Concurrent use of vardenafil orally disintegrating tablets with ribociclib should be avoided due to increased vardenafil exposure. If use of vardenafil oral tablets and ribociclib is required, do not exceed a single dose of 2.5 mg per 24-hour period of vardenafil oral tablets. Also, coadministration of ribociclib with vardenafil should be avoided if possible due to an increased risk for QT prolongation. Ribociclib has been shown to prolong the QT interval in a concentration-dependent manner. Vardenafil can produce QT prolongation at both therapeutic and supratherapeutic doses.
Possible Side Effects of Vardenafil
Ribociclib; Letrozole: (Major) Concurrent use of vardenafil orally disintegrating tablets with ribociclib should be avoided due to increased vardenafil exposure.

Drug Interactions
Ponesimod initiation may result in a transient decrease in heart rate and atrioventricular conduction delays. Ponesimod has not been studied in patients taking concurrent QT prolonging drugs; however, QT prolonging drugs have been associated with TdP in patients with bradycardia. Posaconazole: (Contraindicated) The concurrent use of posaconazole with drugs that are associated with QT prolongation and are also CYP3A4 substrates, such as vardenafil, is contraindicated. Posaconazole is associated with QT prolongation, and vardenafil may cause QT prolongation at both therapeutic and supratherapeutic doses. Elevated plasma concentrations of vardenafil may also increase the risk for other vardenafil-related adverse events, such as prolonged erection or potential for syncope.
