Vidalista 2.5 mg is a low-dose tadalafil medicine used for the treatment of erectile dysfunction (ED) in adult men. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which improve blood flow to the penis during physical stimulation. The main action of Vidalista 2.5 mg is blocking the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP). When PDE5 is inhibited, cGMP levels increase, leading to relaxation of smooth muscles in blood vessels. This allows better blood flow to the penile tissue, helping achieve and maintain an erection when physical aroused.
