Apcalis Oral Jelly is a fast-acting medication used to treat erectile dysfunction (ED) in men. Its active ingredient is tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil works by relaxing blood vessels and increasing blood flow to the pill during physical stimulation, helping men achieve and maintain an ed. Unlike traditional tablets, the oral jelly form allows quicker absorption, which may lead to faster onset of action.
