Malegra Pro 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, the same active ingredient found in Viagra. Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor, which works by relaxing the blood vessels in the penis, increasing blood flow, and thereby helping to achieve and maintain an erection when sexually aroused.It's crucial to consult with a healthcare provider before using Malegra Pro 100 mg to ensure it is safe based on your health history and current medications. Your doctor will determine the appropriate dosage and monitor for any potential interactions or side effects.
