Yes, Tadalista 10 mg (which contains Tadalafil) works by increasing blood flow to the penis, helping to treat erectile dysfunction (ED). Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor, which means it blocks the action of the PDE5 enzyme. This enzyme normally breaks down cyclic guanosine monophosphate (cGMP), a substance that helps relax the smooth muscles in blood vessels, allowing more blood to flow into the penis.

By inhibiting PDE5, Tadalista helps maintain higher levels of cGMP, which in turn causes the blood vessels in the penis to relax and widen, improving blood flow. This makes it easier to achieve and maintain an erection when sexually stimulated.

The Tadalista 10 mg dose is typically taken 30 minutes to 1 hour before sexual activity, and it can remain effective for up to 36 hours, allowing for spontaneity in sexual activity. However, it's important to note that sexual arousal is still necessary for the medication to work—Tadalista doesn't cause an erection on its own, it only helps facilitate the process when you're aroused.
