Levitra

Levitra (vardenafil) is a selective phosphodiesterase type 5 (PDE5) inhibitor clinically prescribed for erectile dysfunction (ED). Its mechanism of action involves:

• Enhancing nitric oxide (NO) effects → promoting smooth muscle relaxation

• Increasing blood flow to the corpus cavernosum → supporting firm erections

• Rapid absorption (noticeable effects in 30 minutes)

• Duration of action: ~4 hours

Key Medical Benefits:

✔ Effective for ED – Works with sexual stimulation to improve erection quality
✔ Potential blood pressure benefits – Due to vasodilatory effects
✔ Possible role in premature ejaculation – Anecdotal reports suggest improved control

Research & Clinical Considerations:

• Gender-neutral vascular effects – Some studies suggest enhanced genital blood flow in women

• Requires intact libido – Does not increase sexual desire (testosterone/libido must be normal)

• Contraindicated with nitrates – Risk of severe hypotension

Levitra remains a well-tolerated PDE5 inhibitor with a lower incidence of visual disturbances compared to sildenafil.
