Zhewitra 20 mg Oral Jelly contains Vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in men. The jelly form allows for rapid absorption, typically within 15–30 minutes, providing a convenient alternative to traditional tablets. Vardenafil works by inhibiting the PDE5 enzyme, which regulates blood flow in the penis. By blocking this enzyme, Zhewitra enhances the effects of nitric oxide, leading to increased blood flow and improved erectile function during sexual arousal.
