Super Tadalis SX is a combination medication that typically contains Tadalafil (the active ingredient in Cialis) and Dapoxetine. This combination is used primarily to treat two conditions: erectile dysfunction (ED) and premature ejaculation (PE) in men. Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor. It works by relaxing the blood vessels in the penis, allowing for increased blood flow when sexually stimulated. This helps men with ED achieve and maintain an erection.
