Cenforce 25 mg contains Sildenafil, which is a medication used to treat erectile dysfunction (ED) in men. Sildenafil belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Cenforce 25 mg is a lower dose of Sildenafil compared to higher-strength formulations such as Cenforce 100 mg or Cenforce 200 mg. The lower dose is typically prescribed for individuals who may not require a higher dose or who are more sensitive to the effects of the medication.
