Vigora 100 mg contains Sildenafil citrate as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in men. Sildenafil is the same active ingredient found in the well-known medication Viagra.

Yes, Vigora 100 mg red tablet can be an effective treatment for ED in many men. The primary mechanism of action of Sildenafil is to increase blood flow to the penis, helping to achieve and sustain an erection during sexual stimulation.

Here's how Vigora 100 mg (Sildenafil) works to improve erectile function:

Inhibition of PDE5: When a man is sexually aroused, the body releases nitric oxide in the erectile tissue of the penis. Nitric oxide stimulates the enzyme guanylate cyclase, leading to increased levels of cyclic guanosine monophosphate (cGMP). cGMP relaxes the smooth muscles in the penile blood vessels, allowing them to dilate and facilitate increased blood flow to the penis. This increased blood flow is what causes an erection.

Sustaining Erection: To maintain an erection, cGMP needs to be present in sufficient amounts. However, an enzyme called PDE5 breaks down cGMP, reducing its levels and leading to the loss of the erection. Vigora 100 mg inhibits the action of PDE5, preventing it from breaking down cGMP. This results in increased cGMP levels, prolonged relaxation of penile blood vessels, and better blood flow, leading to a sustained erection.

It's important to note that Vigora 100 mg, like other PDE5 inhibitors, requires sexual stimulation to be effective. It does not cause spontaneous erections; sexual arousal is still necessary.
