Ne doit pas être utilisé en cas de

• Administration of avanafil tablet to patients using any form of organic nitrate is contraindicated
• Hypersensitivity to any component of the avanafil tablet
• Administration with guanylate cyclase (GC) stimulators such as riociguat and vericiguat Nitrates Administration of avanafil tablets with any form of organic nitrates, either regularly and/or intermittently, is contraindicated.

Interactions

• Avanafil can potentiate the hypotensive effect of nitrates, alpha-blockers, antihypertensives, and alcohol
• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, erythromycin) increase avanafil exposure Potential for Pharmacodynamic Interactions with Avanafil Nitrates Administration of avanafil to patients who are using any form of organic nitrate, is contraindicated. In a clinical pharmacology trial, avanafil was shown to potentiate the hypotensive effect of nitrates.

Mises en garde et précautions

• Patients should not use avanafil if sexual activity is inadvisable due to cardiovascular status or any other reason
• Use of avanafil with alpha-blockers, other antihypertensives, or substantial amounts of alcohol (greater than 3 units) may lead to hypotension
• Patients should seek emergency treatment if an erection lasts greater than 4 hours
• Patients should stop avanafil and seek medical care if a sudden loss of vision occurs in one or both eyes, which could be a sign of Non Arteritic Ischemic Optic Neuropathy (NAION). Avanafil should be used with caution, and only when the anticipated benefits outweigh the risks, in patients with a history of NAION. Patients with a "crowded" optic disc may also be at an increased risk of NAION
• Patients should stop taking avanafil and seek prompt medical attention in the event of sudden decrease or loss of hearing Cardiovascular Risk There is a potential for cardiac risk during sexual activity in patients with pre-existing cardiovascular disease.

Grossesse

Avanafil is not indicated for use in females. There are no data with the use of avanafil in pregnant women to inform any drug-associated risks for adverse developmental outcomes. In animal reproduction studies conducted in pregnant rats and rabbits, no adverse developmental outcomes were observed with oral administration of avanafil during organogenesis at exposures for total avanafil at approximately 8 and 6 times, respectively, the Maximum Recommended Human Dose (MRHD) of...

Mécanisme d'action

The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation. NO then activates the enzyme guanylate cyclase, which results in increased levels of cGMP, producing smooth muscle relaxation in the corpus cavernosum and allowing inflow of blood. Avanafil has no direct relaxant effect on isolated human corpus cavernosum, but enhances the effect of NO by inhibiting PDE5, which is responsible for degradation of cGMP in the corpus cavernosum.
