Tadaflo 5 mg is a medication containing the active ingredient tadalafil, which is primarily used to treat erectile dysfunction (ED) in men. Tadalafil belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Tadaflo works similarly to other medications in its class by increasing blood flow to the penis during sexual stimulation. This increased blood flow helps men achieve and maintain an erection suitable for sexual activity. Tadalafil achieves this by inhibiting the enzyme PDE5, which is responsible for regulating blood flow in the penis. By blocking PDE5, tadalafil allows the blood vessels in the penis to relax and widen, facilitating improved erectile function.
