• Has taken any NSAID or acetaminophen within 12 hours prior to the start of surgery other than aspirin ≤ 150mg/day.

• Suffering from a neurological disorder relating to pain perception or any acute or chronic condition that, in the opinion of the investigator, makes the subject unsuitable from an efficacy or safety perspective.
• In the opinion of the investigator, unable to understand the visual analogue pain score or comply with the protocol requirements.
• Currently or in last 30 days, has been in a clinical trial involving another study drug.
• Currently treated with an ACE inhibitor, warfarin, steroid (other than nasal steroids or topical steroids with the approval of the investigator), cyclosporin, tacrolimus or methotrexate, or any other medication felt by the investigator to interfere with safety or efficacy evaluations.
• Participant weight < 50kg.Suffering from any other diseases or condition which, in the opinion of the investigator, means that it would not be in the participant's best interests to participate in this study.
