Vidalista 20mg is a medication used to treat erectile dysfunction (ED) in men. It contains 20 mg of tadalafil, a long-acting PDE5 inhibitor that improves blood flow to the penis. This helps men achieve and maintain a firm erection during sexual activity when sexually aroused. Tadalafil works by relaxing blood vessels in the penile region, allowing for better circulation. Vidalista 20mg typically starts working within 30 to 60 minutes after ingestion and can remain effective for up to 36 hours, giving users a more flexible window for intimacy.
