Riosiguat ve Sildenafil etkileşimi

Administration with guanylate cyclase (GC) stimulators, such as riociguat.

Concomitant Guanylate Cyclase (GC) Stimulators Do not use SILDENAFIL ORAL FILM in patients who are using a GC stimulator, such as riociguat.

Blood Pressure Decreases Patients with left ventricular outflow obstruction (e.g., aortic stenosis, idiopathic hypertrophic subaortic stenosis) and those with severely impaired autonomic control of blood pressure can be sensitive to the actions of vasodilators, including SILDENAFIL ORAL FILM.

When vasodilators are used in combination, an additive effect on blood pressure may occur.

PDE5 inhibitors, including sildenafil, and alpha-adrenergic blocking agents are both vasodilators with blood pressure lowering effects.

Do not administer within 24 hours of sildenafil.

Phosphodiesterase Inhibitors Concomitant administration of Adempas with specific PDE-5 inhibitors (such as sildenafil, tadalafil, or vardenafil) or nonspecific PDE-5 inhibitors (such as dipyridamole or theophylline) is contraindicated [see Dosage and Administration (2.6), Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.2 )].

PDE Inhibitors: Co-administration of Adempas with specific PDE-5 inhibitors (such as sildenafil, tadalafil, or vardenafil) and nonspecific PDE inhibitors (such as dipyridamole or theophylline), is contraindicated because of hypotension.

Clinical experience with co-administration of Adempas and other phosphodiesterase inhibitors (for example, milrinone, cilostazole, roflumilast) is limited.
