Ne doit pas être utilisé en cas de

• Administration with nitrates and nitric oxide donors
• Administration with guanylate cyclase (GC) stimulators, such as riociguat

Interactions

• Vardenafil can potentiate the hypotensive effects of nitrates, alpha-blockers, and antihypertensives.

Mises en garde et précautions

• Cardiovascular Effects: Patients should not use vardenafil if sex is inadvisable due to cardiovascular status.
• Risk of Priapism: In the event that an erection lasts more than 4 hours, the patient should seek immediate medical assistance.
• Effects on the Eye: Patients should stop use of vardenafil, and seek medical attention in the event of sudden loss of vision in one or both eyes, which could be a sign of nonarteritic anterior ischemic optic neuropathy (NAION). Vardenafil should be used with caution, and only when the anticipated benefits outweigh the risks, in patients with a history of NAION.
• Sudden Hearing Loss: Patients should stop vardenafil and seek medical attention in the event of sudden decrease or loss in hearing.
• Alpha-Blockers: Caution is advised when PDE5 inhibitors are coadministered with alpha-blockers. In some patients, concomitant use of these two drug classes can lower blood pressure significantly leading to symptomatic hypotension (for example, fainting).
• QT Prolongation: Patients with congenital QT syndrome or taking class IA or III antiarrhythmics should avoid using vardenafil.
• The evaluation of erectile dysfunction should include a medical assessment, a determination of potential underlying causes and the identification of appropriate treatment. Before prescribing vardenafil, it is important to note the following:

Grossesse

Vardenafil is not indicated for use in females. There are no data with the use of vardenafil in pregnant women to inform any drug-associated risks. In animal reproduction studies conducted in pregnant rats and rabbits, no adverse developmental outcomes were observed with oral administration of vardenafil during organogenesis at exposures for unbound vardenafil and its major metabolite at approximately 100 and 29 times, respectively, the maximum recommended human dose (MRHD)...

Mécanisme d'action

Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles. During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum. Nitric oxide activates the enzyme guanylate cyclase resulting in increased synthesis of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum.
