Vidalista 40mg, containing the active ingredient Tadalafil, works by increasing blood flow to the penis during stimulation. It belongs to a class of medications called phosphodiesterase type 5 inhibitors, which relax the blood vessels in the penis to allow for more blood flow. This increased blood flow helps a man get and maintain an erection when aroused.
While Vidalista 40mg is similar to Viagra, which contains Sildenafil citrate, it works more quickly and lasts longer due to the difference in the active ingredient.
