Vidalista 2.5 mg contains tadalafil as its active ingredient, and it belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors. The mechanism of action of Vidalista 2.5 mg involves its interaction with the enzyme PDE5 in the smooth muscle cells of the blood vessels.
Here's a step-by-step explanation of the mechanism of action:
Release of Nitric Oxide: Sexual stimulation leads to the release of nitric oxide (NO) in the erectile tissue of the penis.
Activation of Guanylate Cyclase: Nitric oxide activates an enzyme called guanylate cyclase, leading to an increase in cyclic guanosine monophosphate (cGMP) levels.
Smooth Muscle Relaxation: Elevated cGMP levels cause relaxation of the smooth muscles in the blood vessels of the penis (corpus cavernosum). This relaxation allows increased blood flow into the erectile tissue, leading to an erection.
PDE5 Inhibition: Normally, the enzyme PDE5 breaks down cGMP, regulating its levels. Tadalafil, the active ingredient in Vidalista 2.5 mg, inhibits PDE5. By blocking PDE5, tadalafil prolongs the effects of cGMP, promoting sustained smooth muscle relaxation and prolonged blood flow to the penis.
Erection Support: The enhanced blood flow facilitates the achievement and maintenance of an erection when sexual stimulation is present.
It's important to note that Vidalista 2.5 mg does not cause an automatic erection; sexual stimulation is necessary to activate the release of nitric oxide and initiate the process.
The PDE5 inhibition by tadalafil is selective for the corpus cavernosum in the penis, making it a targeted treatment for erectile dysfunction. The medication's duration of action is longer compared to some other PDE5 inhibitors, allowing for a more extended window of effectiveness. Always follow the prescribed dosage and instructions provided by a healthcare professional when using Vidalista 2.5 mg or any medication containing tadalafil.
