Zhewitra 40 mg contains vardenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, facilitating the achievement and maintenance of an erection during sexual stimulation. Zhewitra 40 mg contains 40 milligrams of vardenafil, which is a moderate dose. It is typically prescribed for individuals with ED who may require a higher dose than the standard 20 mg. Dosages may vary depending on individual response and tolerability.
