The active ingredient in Vidalista 60 mg is Tadalafil, which is a phosphodiesterase type 5 inhibitor. PDE5 is an enzyme that causes the blood vessels in the penis to constrict, which decreases blood flow and makes it difficult to achieve an erection. By inhibiting PDE5, Vidalista 60 mg increases blood flow to the penis, which helps a man achieve and maintain an erection during sexual stimulation.
Vidalista 80 mg is a higher dose of the drug than some other available dosages, and it is usually prescribed for men who have more severe cases of ED. The tablet should be taken orally with a glass of water, and it is recommended to take it 30 minutes to an hour before sexual activity. The effects of Vidalista 60 mg can last for up to 36 hours, which means that it can provide a longer window of opportunity for sexual activity.
