Tadalista 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Tadalafil, a powerful ingredient that improves blood flow to the penis by relaxing the blood vessels. This medicine belongs to a group called PDE5 inhibitors. Erectile dysfunction, also known as inability to maintain an erection, can be caused by physical or psychological issues. Tadalista 20 mg helps by allowing more blood to enter the penis during sexual arousal, leading to a firm and lasting erection. When a man is sexually aroused, the body releases nitric oxide in the penis. This triggers the production of a natural chemical called cGMP, which controls how blood flows in and out of the penis. Tadalista 20 mg increases cGMP levels, helping you get and keep an erection.
