Silagra 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is the same active ingredient found in Viagra. Silagra works by relaxing the blood vessels in the penis, allowing for increased blood flow, which in turn helps men achieve and maintain an erection when sexually aroused. It's important to use Silagra as directed by a healthcare professional and to be aware of potential side effects and contraindications.
