The specific ingredient responsible for vasodilation in Vidalista Professional is Tadalafil. Tadalafil is a member of the phosphodiesterase type 5 (PDE5) inhibitor class of drugs, widely used to treat erectile dysfunction (ED).
Tadalafil works by blocking the enzyme PDE5, which normally breaks down cyclic guanosine monophosphate (cGMP) in the smooth muscle cells lining blood vessels. By inhibiting PDE5, tadalafil increases the levels of cGMP. Elevated cGMP causes relaxation of smooth muscle cells in the blood vessel walls, leading to vasodilation—the widening of blood vessels.
This vasodilation improves blood flow, particularly in the penile arteries, which facilitates the achievement and maintenance of an erection during sexual stimulation. The effect is not limited to the penis; tadalafil can also cause vasodilation in other parts of the body, which is why it may lower blood pressure slightly.
Vidalista Professional may also contain additional inactive ingredients to aid absorption or improve the formulation, but tadalafil is the active component responsible for the therapeutic effect, including vasodilation.
In summary, tadalafil is the key ingredient in Vidalista Professional that causes vasodilation by increasing cGMP levels and relaxing blood vessels, thereby helping treat erectile dysfunction effectively.
