Description: Thiocolchicotat is a muscle relaxant and works on the centres in your brain and spinal cord to help relieve muscle stiffness or spasms and improve the pain and movement of your muscles. Muscle relaxation helps to ease muscle tension and pain. Ketorolac Tromethamine (Keto) is an NSAID (non-steroidal anti-inflammatory drug). It blocks the production of prostaglandins that cause swelling and pain. Ketoprofen, ketorolac, and ketorolac tromethamine are all names for the same active ingredient.
