Malegra Pro 100 mg is marketed as a sildenafil-containing medicine for erectile dysfunction (ED). Sildenafil is a PDE5 inhibitor that improves blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. When appropriately prescribed, sildenafil can contribute to positive sexual-health outcomes by improving erection firmness, maintenance, sexual satisfaction, and confidence. Clinical trials found significantly better erectile function and successful intercourse rates with sildenafil than with placebo.
