Men with erectile dysfunction can be treated with medications such as Vidalista Professional. Tadalafil, an inhibitor of phosphodiesterase type 5, is one of its components. The active ingredient in Vidalista Professional, which improves blood flow to the penis during sexual stimulation, helps men get and maintain an erection. An erection is encouraged and blood flow is increased when sexual excitement takes place by helping the smooth muscles of the penile blood vessels to relax. It usually takes 30 to 1 hour before having sex, and the aftereffects may last for 36 hours. Vidalista Professional should be kept in a single, secure container.
