Interactions of avanafil

Avanafil enhances the antihypertensive effects of nitro-based vasodilators. Therefore, the joint application is prohibited. If a patient who has taken avanafil within the last 12 hours or more has been given nitrates because of a life-threatening situation (such as a heart attack), the blood pressure may be lowered.

Avanafil has a vasodilating effect on the penis, but this effect can affect the whole body. Therefore, the drug increases the blood pressure reduction by appropriate drugs (alpha sympatholytic, calcium channel blocker). It can cause dizziness, drowsiness or fainting.

Avanafil is degraded by an easily influenced enzyme system. Therefore, the application is prohibited with strong inhibitors of these enzymes. These include: the fungicides itraconazole and ketoconazole, the antiviral agents atazanavir, indinavir, nelfinavir, ritonavir and saquinavir, the antibiotics clarithromycin and telithromycin and the antidepressant nefazodone.

Patients receiving at the same time weaker inhibitors of this enzyme (the antibiotic erythromycin, the antifungal agent fluconazole, the antiviral agents amprenavir and fosamprenavir, aprepitant (for nausea and vomiting), and the antidiabetic diltiazem or verapamil but also grapefruit juice) should not exceed the maximum dose of avanafil (100 Milligrams). Between the individual revenues should be a time interval of at least 48 hours.

Consuming alcohol while using spedra may increase the likelihood of a sudden drop in blood pressure. Therefore, you should abstain from drinking while taking.

Drugs that accelerate the degradation of avanafil may affect its performance. These include the antiepileptic drugs carbamazepine and phenobarbital, the tuberculosis drug rifampicin, the antiviral agent efavirenz and bosentan (for pulmonary hypertension). Although there are no studies, but should be avoided as a precaution, the joint application.
