– Vardenafil (Levitra, Staxyn): Similar in action to sildenafil, vardenafil typically has an onset of about 30 to 60 minutes, and its effects final for about five hours.
– Avanafil (Stendra): This newer PDE5 inhibitor works sooner than the others, often taking impact in as little as 15 minutes, with effects lasting for about six hours.

When sexual stimulation happens, the physique produces nitric oxide. The increased levels of cGMP assist sustain an erection. When one takes a PDE5 inhibitor, they enhance the availability of cGMP, resulting in enhanced erectile operate.
Alprostadil, alternatively, mimics the action of NO straight, inflicting blood vessels to dilate and permitting increased blood stream. This mechanism does not depend on sexual want; thus, it can be efficient even in circumstances where the underlying causes are primarily psychological.
Unwanted side effects
While erectile dysfunction medications could be effective, they can also include unwanted effects. Some frequent unwanted side effects of PDE5 inhibitors embrace:
- Headache: The most reported aspect impact associated with the use of PDE5 inhibitors, usually mild to reasonable in intensity.
- Facial flushing: A standard prevalence on account of widened blood vessels.
- Nasal congestion: Occasions of mild nasal blockage usually are not uncommon.
- Indigestion: Some users report gastrointestinal discomfort.
- Imaginative and prescient changes: In rare circumstances, visual disturbances can happen, especially with sildenafil and vardenafil, affecting shade notion.
- Hearing loss: There have been rare experiences of sudden hearing loss with the usage of PDE5 inhibitors.
