Cenforce Soft is marketed as a sildenafil medicine for treating erectile dysfunction (ED) in adult men. Sildenafil belongs to the phosphodiesterase type 5 (PDE5) inhibitor class. It works by increasing blood flow to the penis during sexual stimulation, helping a man achieve and maintain an erection. Sildenafil must not be taken with nitrate medicines, including nitroglycerin, because the combination can cause a potentially dangerous drop in blood pressure. People with heart disease, low blood pressure, or those taking certain blood-pressure or prostate medicines should consult a healthcare professional before using it.
