Tadalafil works by inhibiting the enzyme PDE5, which leads to the relaxation of smooth muscles and dilation of blood vessels in the penis. This enhances blood flow to the area and helps men achieve and maintain an erection when sexually stimulated.Unlike other ED medications, Tadalafil has a long half-life, meaning it can remain active in the body for up to 36 hours. This provides more flexibility in the timing of sexual activity, allowing for spontaneous sex without having to plan around a strict dosing schedule.
