Vidalista 40 mg is a medication used to treat erectile dysfunction (ED) in men. It contains tadalafil as its active ingredient, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors.
When a man is sexually aroused, his body releases a chemical called nitric oxide, which stimulates the production of cyclic guanosine monophosphate (cGMP). This chemical is responsible for relaxing the blood vessels in the penis, allowing more blood to flow into the penis and leading to an erection.
However, in men with ED, the enzyme PDE5 breaks down cGMP too quickly, making it difficult to achieve or maintain an erection. Vidalista 40mg works by inhibiting the action of PDE5, which allows cGMP to accumulate in the penis and leads to better blood flow, resulting in a harder and longer-lasting erection.
