Zhewitra 40 mg is marketed as a tablet containing vardenafil, a phosphodiesterase type-5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in adult men. Vardenafil works by increasing blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. It does not increase sexual desire and requires sexual stimulation to produce an erection. An important safety consideration is that 40 mg is above the standard recommended maximum dose of vardenafil.
