Clonidine

Tramadol, sold under the brand name Ultram among others, is an opioid pain medication used to treat moderate to moderately severe pain. When taken by mouth in an immediate-release formulation, the onset of pain relief usually occurs within an hour. It is often combined with paracetamol (acetaminophen) as this is known to improve the efficacy of tramadol in relieving pain.
