Cenforce 200 mg inhibits the enzyme PDE5 (phosphodiesterase type 5) in the body. This inhibition allows the body to maintain higher levels of cyclic GMP, a compound that helps relax the smooth muscles in the blood vessels of the penis. This relaxation enables increased blood flow, which leads to a stronger erection when sexually aroused. Typically, Cenforce 200 mg starts to take effect within 30 to 60 minutes after ingestion, making it a quick solution for many men dealing with ED. The effects of Cenforce 200 mg usually last around 4 to 6 hours, giving men a window of opportunity to engage in sexual activity without the pressure of timing.
