Cenforce 100 mg is a widely used oral medication for the treatment of erectile dysfunction (ED) in men. It contains 100 mg of Sildenafil Citrate—the same active ingredient found in Viagra—and belongs to the class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors.

Cenforce 100 mg works by increasing blood flow to the penis during sexual stimulation. It does this by inhibiting the PDE5 enzyme, which allows the smooth muscles in the blood vessels of the penis to relax, facilitating improved blood circulation and enabling a firm, lasting erection when aroused.

Cenforce 100 mg is one of the most commonly prescribed strengths for men with moderate to severe erectile dysfunction. It typically starts working within 30 to 60 minutes of ingestion and remains effective for about 4 to 6 hours, although this can vary based on the individual's metabolism, health condition, and whether it was taken on an empty stomach or after a heavy meal. 

Cenforce 100 is not meant for daily use unless prescribed in a daily lower-dose regimen. It should be taken only once in 24 hours, and exceeding this limit can increase the risk of complications without enhancing its benefits.
