Zhewitra 40 mg is a medication that contains vardenafil as its active ingredient. Vardenafil is a phosphodiesterase type 5 (PDE5) inhibitor, and it is used to treat erectile dysfunction (ED) in adult men. Erectile dysfunction is a condition characterized by the inability to achieve or maintain an erection sufficient for sexual activity. Vardenafil, like other PDE5 inhibitors, works by blocking the action of the enzyme phosphodiesterase type 5. This inhibition results in increased levels of cyclic guanosine monophosphate (cGMP), leading to smooth muscle relaxation in the corpus cavernosum of the penis and increased blood flow, facilitating an erection.
