Tadarise Pro 40 mg 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. Tadarise Pro 40 mg works by inhibiting the enzyme PDE5, which regulates blood flow in the penis. By blocking PDE5, it allows the blood vessels to relax and expand, increasing blood flow when sexually stimulated.
