Sildigra 250 mg is a medication primarily used to treat erectile dysfunction (ED). It contains Sildenafil Citrate, the same active ingredient found in Viagra, which is a PDE5 inhibitor. Sildigra 250 mg is a high-dose formulation of Sildenafil, and it is typically used when lower doses of Sildenafil are not effective for treating ED. Sildenafil works by improving blood flow to the penis, allowing men to achieve and sustain an erection during sexual activity.
