Zhewitra 40 Mg is a medication primarily used to treat erectile dysfunction by improving blood flow to the penis during sexual stimulation. It contains vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor, which works by relaxing the muscles in the blood vessels of the penis, allowing for increased blood flow and thus facilitating erections. This medication is typically taken orally and should be consumed as directed by your healthcare provider.
