Vidalista 5 mg is a medicine used to treat Erectile Dysfunction (ED). It contains Tadalafil, the same active ingredient as in Cialis, and belongs to a group of medicines called PDE5 inhibitors. These medicines help increase blood flow to the penis. The key benefit of Vidalista 5 mg is that it supports a natural and lasting erection when a man is sexually aroused. ED can be caused by various physical or psychological factors. Vidalista 5 mg helps overcome these by improving blood circulation. An erection happens when sexual arousal causes the blood vessels in the penis to widen, allowing more blood in, while the vessels that carry blood away tighten. This traps blood in the penis, resulting in an erection. Nitric oxide is released during sexual stimulation. This chemical boosts the production of cGMP, which controls how blood vessels open and close, making an erection possible.
