One well-known drug for treating male erectile dysfunction (ED) is suhagra 100. The active ingredient in Suhagra, sildenafil citrate, is the same as that in Viagra and is produced by Cipla, one of India's top pharmaceutical businesses. As a PDE5 inhibitor, sildenafil promotes a hard and long-lasting erection by relaxing blood vessels and enhancing blood flow to the penis during sexual stimulation.
