Silditop 100 is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil works by relaxing the blood vessels in the penis, allowing increased blood flow to the area, which helps in achieving and maintaining an erection during sexual stimulation. Silditop 100 is similar to other sildenafil-containing medications like Viagra, but it comes in a strength of 100 mg per tablet. The higher strength is intended for individuals who may require a stronger dose of sildenafil to achieve the desired effect.
