Malegra Pro 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate as its active ingredient. Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor, which works by increasing blood flow to the penis during sexual stimulation. This helps men achieve and maintain an erection sufficient for sexual activity. Malegra Pro 100 mg is typically taken orally as needed, approximately 30 minutes to 1 hour before sexual activity. The effects of sildenafil citrate can last for up to 4 to 6 hours, providing a window of time during which sexual activity can occur. https://www.genericday.com/malegra-pro-100-mg.html
