Silditop 100 mg is a medicine containing sildenafil citrate 100 mg. It belongs to a group of medicines called PDE-5 inhibitors and is primarily used to treat erectile dysfunction (ED) in adult men. Available product information identifies Silditop 100 mg as a sildenafil citrate tablet manufactured by Healing Pharma. Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping a man achieve and maintain an erection. It does not increase sexual desire by itself, and sexual stimulation is still required for an erection to occur. Silditop 100 is generally taken orally before sexual activity, according to a healthcare professional's instructions. The 100 mg strength is at the upper end of the usual recommended ED dose, so it should not be increased or combined with other sildenafil-containing medicines unless specifically advised by a doctor.
