Sildigra 250mg is a medication used primarily to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient found in Viagra and other ED medications. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor that works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. Sildenafil in Sildigra 250mg works by blocking the PDE5 enzyme in the penis, which allows cyclic GMP to accumulate. Alcohol can enhance side effects like dizziness and headaches, so limiting alcohol consumption while using this medication is advised.
