Malegra 100 mg is a medication primarily used to treat erectile dysfunction (ED) in men. It contains Sildenafil citrate as its active ingredient, which is also found in Viagra. Sildenafil works by relaxing the blood vessels in the penis, which increases blood flow and helps men achieve and maintain an erection when sexually aroused. If you have any specific questions about Malegra or if you are considering using it, it’s important to consult with a healthcare provider.
