Cenforce 100 is a medication containing sildenafil citrate, which is most commonly used to treat erectile dysfunction (ED). It works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5), which leads to increased blood flow to the penis and facilitates an erection when sexually stimulated. Although Cenforce 100 is primarily prescribed for ED, its mechanism of action has generated interest in its potential benefits for other conditions, including sexual dysfunction related to MS.
