Tadarise 60 mg contains the active ingredient Tadalafil. This drug works by preventing the action of the enzyme phosphodiesterase-5 to widen or relax blood vessels and improve blood flow to the penis. Increased blood flow leads to an erection. The drug will only assist in the process of erection, but sexual stimulation is needed in order for it to work. Tadalafil also helps BPH by relaxing the muscles in the prostate and bladder area to improve blood flow.
