Malegra is a medication commonly prescribed to treat erectile dysfunction (ED) in men. Its active ingredient is sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor that helps improve blood flow to the penis, facilitating an erection during sexual stimulation. Malegra works by blocking the PDE5 enzyme, which breaks down cyclic GMP, a molecule responsible for relaxing smooth muscle and allowing increased blood flow in the penile tissue. This mechanism helps men with ED achieve and maintain an erection sufficient for sexual activity. https://www.genericday.com/malegra.html
