Tadalista 20 is a medication used to treat erectile dysfunction (ED) in men. It contains Tadalafil as the active ingredient, which is also found in well-known ED medications like Cialis. Tadalista 20 helps to improve blood flow to the penis, facilitating an erection when sexually aroused.

Tadalafil is a PDE5 inhibitor that works by blocking the enzyme PDE5, which usually restricts blood flow to the penis. By inhibiting this enzyme, Tadalafil helps relax the blood vessels in the penis, increasing blood flow during sexual arousal and facilitating the ability to achieve and maintain an erection.

Tadalafil blocks the action of PDE5, allowing the smooth muscles in the blood vessels of the penis to relax and expand. This improves blood flow and helps facilitate an erection in response to sexual stimulation.

For Tadalista to work, sexual stimulation is required. The medication helps enhance the body's natural response to arousal, but it doesn't work without it.
