Vidalista 40 is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient Tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. This medication works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. Vidalista 40 contains Tadalafil as its active ingredient, which is the same ingredient found in the well-known ED medication Cialis. The typical recommended dose of Vidalista 40 is one tablet taken orally about 30 minutes to an hour before sexual activity. The dosage may vary depending on individual needs, and it's important not to exceed the recommended dose.
