Tadalista Professional is a medication primarily used to treat erectile dysfunction (ED) in men. It contains tadalafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil works by increasing blood flow to the penis during sexual stimulation, enabling men with ED to achieve and sustain an erection. Tadalafil, the active ingredient in Tadalista Professional, inhibits the action of the enzyme PDE5. This inhibition allows the smooth muscles in the blood vessels of the penis to relax, promoting increased blood flow to the area during sexual arousal. This improved blood flow facilitates the ability to achieve and maintain an erection.
