Vardenafil is indicated for the treatment of erectile dysfunction in adult men, a condition characterized by the inability to achieve or maintain a penile erection sufficient for satisfactory sexual performance.
Vardenafil inhibits the enzyme phosphodiesterase type 5 (PDE5), which normally breaks down cyclic guanosine monophosphate (cGMP). By preventing this breakdown, the medication prolongs the effects of nitric oxide, leading to smooth muscle relaxation in the corpus cavernosum and increased blood flow to the penis during sexual stimulation.
This medication requires sexual stimulation to be effective and should not be used in combination with nitrates or certain other medications. It is contraindicated in patients with cardiovascular conditions where sexual activity is not advisable. Common side effects may include headache, flushing, nasal congestion, and visual disturbances. Patients should consult their healthcare provider for appropriate dosing and to assess cardiovascular risk before use.
