Cenforce 100 contains the same active ingredient as Viagra but is more budget-friendly, making it accessible to a broader population of men seeking ED treatment. Cenforce 100 mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE-5) in the penis. PDE-5 is responsible for breaking down a molecule called cyclic guanosine monophosphate (cGMP), which promotes smooth muscle relaxation and increased blood flow in the penis during sexual stimulation.
