Silditop 100 mg is a medication primarily used for the treatment of erectile dysfunction (ED) in men. Its active ingredient is Sildenafil Citrate, which belongs to the class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil works by relaxing the blood vessels in the penis, allowing increased blood flow during sexual stimulation, which helps achieve and maintain an erection. Silditop 100 mg is usually taken orally, about 30–60 minutes before sexual activity. Its effects can last for 3–5 hours, although this can vary depending on individual metabolism and other factors. It should generally be taken once per day, and it is advised to avoid alcohol and high-fat meals, as these can reduce its effectiveness.
