Vidalista tadalafil belongs to the class of medicine called phosphodiesterase type 5 inhibitors and has an unmatched strength. The blood arteries of a man's penis relax during intercourse, allowing blood to flow into it. Take Vidalista tadalafil no more than once every day. Patients should take one pill with a glass of water 30 to 60 minutes before they wish to engage in sexual activity. Only guys who are sexually aroused can benefit from this medication in terms of erection. However, each person experiences the medicine's effects for a different amount of time.
