The purpose of Vidalista 20 mg is to increase blood flow to the penis by relaxing the smooth muscles in the blood vessels, allowing for a firm and lasting erection when sexually aroused. It does not cause spontaneous erections and requires sexual stimulation to work. Because Tadalafil remains in the bloodstream for a prolonged period, its effects are longer-lasting, which allows for more spontaneity in sexual activity without the need to precisely time the dose. Additionally, Vidalista 20 mg should be taken with a full glass of water, and ideally 30 to 60 minutes before sexual activity.
