We studied 90 adults undergoing surgical removal of at least both lower
third molar teeth as day cases under standardized general anaesthesia.
Patients were allocated randomly (with stratification for surgeon) to
receive tenoxicam 40 mg, tenoxicam 20 mg or placebo i.v. at induction of
anaesthesia and orally (effervescent tablets) with food on each of the
subsequent 2 days. Panadeine (paracetamol 500 mg-codeine 8 mg) was given
before operation and was available as needed for pain thereafter, to a
limit of two tablets every 4 h. Nefopam i.v. was also available. Efficacy
variables and adverse reactions were assessed over 6 days. Over the 6-day
period, patients who received tenoxicam reported less pain on rest (area
under the curve; P < 0.05) and less disturbance in sleep (P < 0.01)
even though they used fewer Panadeine tablets (P < 0.05). Differences
between tenoxicam 40 mg and 20 mg were not significant. There was no
significant difference in nefopam requirements or side effects, and no
adverse event attributable to the study medication.
