Tadalafil, the active ingredient in Vidalista 20mg, works by increasing blood flow to the penis during sexual stimulation. It inhibits the action of the PDE5 enzyme, allowing the smooth muscles in the blood vessels of the penis to relax, resulting in an improved and longer-lasting erection.The typical starting dose of Vidalista is 10mg, which can be increased to 20mg or decreased to 5mg based on individual response and the advice of a healthcare provider. It is usually taken 30 minutes to 1 hour before sexual activity, and its effects can last up to 36 hours.
