Stimu-Max 100mg 5 Tablets

Medication Name: Sildenafil

Pharmacological Class:
Phosphodiesterase type 5 (PDE5) inhibitor

Active Ingredient:
Sildenafil citrate

Indications:

• Erectile dysfunction (ED): Enhances the ability to achieve and maintain an erection during sexual stimulation.

Sildenafil blocks the PDE5 enzyme responsible for the breakdown of cyclic guanosine monophosphate (cGMP). Elevated cGMP levels relax smooth muscle in penile blood vessels, increasing blood flow to the corpus cavernosum and facilitating erection.
