Tadacip 20 is a medication primarily used to treat erectile dysfunction (ED) in men, as well as symptoms associated with benign prostatic hyperplasia (BPH), a condition where the prostate gland becomes enlarged. The active ingredient in Tadacip 20 is tadalafil, which belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. These drugs work by increasing blood flow to the penis, thereby helping men with ED achieve and maintain an erection in response to sexual stimulation.
