Extra Super Zhewitra is a prescription combination medicine used to treat two male sexual health conditions at the same time: erectile dysfunction (ED) and premature ejaculation (PE). It contains two active ingredients—vardenafil and dapoxetine—which work through different mechanisms. Vardenafil is a phosphodiesterase type 5 (PDE5) inhibitor. It improves erectile function by increasing blood flow to the penis during sexual stimulation. It works by blocking the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP). https://www.genericday.com/extra-super-zhewitra.html
