Cenforce Soft is commonly marketed as a soft-tablet formulation containing sildenafil, a PDE5 inhibitor used to treat erectile dysfunction (ED) in adult men. Because formulations can vary between products and manufacturers, check the packaging for the exact active ingredient and strength. Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. It does not increase sexual desire and cannot produce an erection without sexual stimulation.
