Tadalafil, a PDE5 inhibitor and the active component in Vidalista 20, is a phosphodiesterase type 5 (PDE5) inhibitor. An enzyme called PDE5 causes the blood vessels in the penis to constrict, which reduces blood flow and makes getting an erection challenging. The increase in blood flow to the penis caused by Vidalista 20's inhibition of PDE5 enables a man to achieve and sustain an erection during sexual stimulation.
For men who have more severe cases of ED, Vidalista 20 mg is typically prescribed because it is a higher dosage of the medication than some other available dosages. The tablet should be swallowed whole with a glass of water, and taking it 30 to 60 minutes before engaging in sexual activity is advised. Vidalista 20 can extend the window of opportunity for sexual activity because its effects can last for up to 36 hours.
