Malegra 200 mg is a medication used to treat erectile dysfunction (ED), containing 200 mg of Sildenafil Citrate, a phosphodiesterase type 5 (PDE5) inhibitor. It works by increasing blood flow to the penis to help achieve and maintain erections. Since low testosterone can contribute to ED, men with hormonal deficiencies might need additional treatments such as testosterone replacement therapy alongside PDE5 inhibitors like Malegra.
