1. Male / female patients, 18-65 years of age inclusive.
2. Body mass index (BMI) 18-35
3. Patient is in good health as determined by the Principal Investigator on the basis of medical history and physical examination.
4. American Society of Anesthesia (ASA) Grade I or Grade II scheduled for elective surgical extraction of 1 or more impacted mandibular 3rd molars, at least 1 of which must be a fully or partially impacted mandibular 3rd molar requiring mandibular bone removal.
5. Patient has provided written informed consent prior to performing any study related procedures.
6. A negative urine pregnancy test for all female patients of childbearing potential (a female is considered to be of childbearing potential if they have not been postmenopausal for at least 24 consecutive months or if they have a uterus and at least one ovary) immediately before surgery.
7. Patients will be randomized and assigned medication if they rate their pain as moderate or severe assessed on a four-point verbal rating scale (VRS) within 4 hours after the completion of surgery.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range
1. Another acute or chronic painful physical condition.
2. The use of nonsteroidal antiinflammatory drugs (NSAIDs), including aspirin, or other analgesic drugs within the 24 hours preceding administration of study medication. Specifically excluded are tricyclic antidepressants (TCAs), narcotic analgesics, antihistamines, tranquilizers, hypnotics, sedatives, Cyclooxegenase-2 (COX-2) specific inhibitors and corticosteroids.
3. The use of any anticoagulant including heparin, warfarin and low-molecular weight heparins at screening and throughout the study.
4. The patient has a history of uncontrolled chronic disease, which in the opinion of the Principal Investigator would contraindicate study participation.
5. Inability to use or understand the visual analog scale (VAS) pain score
and/or the Verbal Rating Score (VRS).
6. Liver dysfunction defined as an elevation of alanine aminotransferase (ALT), aspartate aminotransferase (AST) or gamma glutamyl transpeptidase (GGT) 3 times above the upper limit of normal (ULN).
7. Advanced renal dysfunction defined as an elevation of serum creatinine 3 times the ULN.
8. Psychiatric or medical conditions which would preclude safe surgery.
9. Concomitant use of sedatives or microsomal enzyme inducers.
10. Pregnant or lactating women.
11. Women of childbearing potential not using adequate contraception.

14. A contraindication to paracetamol.
15. History of non-response to paracetamol.
16. A bleeding disorder.
17. Any history of gastrointestinal bleeding.
18. Any laboratory abnormality, which in the opinion of the Principal Investigator would preclude study participation.
