Vidalista 60 mg is a medication primarily used to treat erectile dysfunction (ED) in men. It contains the active ingredient tadalafil, which belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors.
Here's how Vidalista 60 mg works to treat erectile dysfunction:
- Inhibition of PDE5:
- The key mechanism of action of Vidalista 60 mg involves inhibiting the activity of the enzyme PDE5. PDE5 is found in the smooth muscle cells of the blood vessels in the penis.
- Enhancement of Nitric Oxide (NO) Action:
- When a man is sexually stimulated, the release of nitric oxide (NO) occurs in the erectile tissue of the penis. Nitric oxide activates an enzyme called guanylate cyclase, leading to an increase in cyclic guanosine monophosphate (cGMP) levels.
- Relaxation of Smooth Muscles:
- Increased cGMP levels cause relaxation of the smooth muscles in the penile blood vessels, allowing them to dilate. This dilation enhances blood flow to the penis, resulting in an erection.
- Improved Blood Flow:
- By inhibiting PDE5, Vidalista 60 mg prolongs the action of cGMP, maintaining the relaxation of smooth muscles and promoting increased blood flow to the penis. This enhanced blood flow is crucial for achieving and maintaining an erection during sexual stimulation.
- Erection Maintenance:
- Vidalista 60 mg helps men with ED achieve and sustain an erection by supporting the natural physiological processes involved in the erectile response. It does not cause an automatic erection but facilitates the response to sexual stimulation.
