Tadalista 20 is a medication used for the treatment of erectile dysfunction (ED) in men. The active ingredient in Tadalista 20 is Tadalafil, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors.

When a man is sexually stimulated, his body releases nitric oxide, which stimulates the production of cyclic guanosine monophosphate (cGMP). cGMP helps to relax the smooth muscles in the blood vessels of the penis, allowing more blood to flow into the penis and causing an erection.

However, in men with ED, the enzyme PDE5 breaks down cGMP too quickly, making it difficult to achieve or maintain an erection. Tadalafil in Tadalista 20 works by inhibiting the action of PDE5, which leads to an increase in cGMP levels, allowing the smooth muscles in the penis to relax, and increasing blood flow to the penis.

Tadalista 20 should be taken about 30 minutes before sexual activity, and the effects can last for up to 36 hours. It is important to note that sexual stimulation is necessary for Tadalista 20 to be effective.
