Cenforce 100, which contains sildenafil citrate, is a widely used medication for treating erectile dysfunction (ED) in men. According to recent medical research, it works by increasing blood flow to the penis by inhibiting the PDE5 enzyme. Studies have shown that Cenforce 100 is effective in up to 80% of men with ED when taken 30–60 minutes before sexual activity. Research highlights that its effectiveness is comparable to Viagra, though it is often more affordable. However, medical experts caution that it should be used under a doctor’s guidance, especially for men with heart conditions or those taking nitrates, due to potential side effects such as headaches, flushing, or changes in vision.
