Silditop 100 mg is a prescription medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient found in Viagra. As a phosphodiesterase type 5 (PDE5) inhibitor, Sildenafil works by enhancing blood flow to the penis during sexual stimulation, helping men achieve and maintain a firm erection. The 100 mg dose of Silditop is considered a high strength, typically prescribed to men who do not achieve the desired effect with lower doses like 25 mg or 50 mg. It should be taken orally, about 30 to 60 minutes before planned sexual activity, and its effects can last for 4 to 6 hours.
