Tenoxicam and diclofenac sodium were compared as analgesics following the surgical removal of third molars. Twenty-five patients between the ages 17 and 29 years were randomly allocated into two groups. Patients in group A received a single intraoperative intravenous (i.v.) injection of 20 mg of tenoxicam followed by a 20-mg tablet given the evening after the operation; thereafter, one 20-mg tablet was given once daily for the next 6 days. Group B received a single intraoperative intramuscular injection of 75 mg of diclofenac sodium followed by a 50-mg tablet 4 to 6 hours postoperatively and during the evening; thereafter, a 50-mg tablet was taken three times daily for the next 6 days. Pain was postoperatively measured hourly for 4 hours and later in the evening. Pain was also measured in the mornings and evenings for the next 6 days. The highest pain scores were obtained 1 hour postoperatively for both groups. During the first 3 hours following administration, patients in the tenoxicam group experienced significantly more pain than those in the diclofenac group. Preoperatively, both treatments showed identical efficacy after 3 hours. It is therefore suggested that a 40-mg dose of i.v. tenoxicam should be administered at induction of anesthesia to achieve a higher level of analgesia in the immediate postoperative phase.

The analgesic efficacy and duration of action of tenoxicam, an injectable non-steroidal analgesic with a long elimination half-life, were studied in day case laparoscopy in a double-blind randomised prospective parallel placebo-controlled trial. Tenoxicam 20 mg or saline was given intravenously at induction of anaesthesia in 67 women undergoing day case investigative laparoscopy for infertility or abdominal pain. Outcome measures were time to first analgesia, pain levels at 2, 4 and 24 h plus postoperative analgesic consumption in hospital and at home. The study showed no statistically significant difference in any of these measures between the two groups. Tenoxicam 20 mg intravenously immediately pre-operatively cannot be recommended for day case surgery on the basis of this study.

The present study provides an important implication for the management of chronic neuropathic pain, focusing on prostaglandin (PG) and nitric oxide (NO) in the spinal cord. To determine if spinally administered cyclooxygenase (COX) inhibitor or nitric oxide synthase (NOS) inhibitor had preemptive analgesia on thermal hypersensitivity induced by chronic constrictive nerve injury, Sprague-Dawley rats were chronically implanted with an intrathecal (i.t.) catheter. The left sciatic nerve was loosely ligated with 2-mm polyethylene tubing to produce painful mononeuropathy. Animals received tenoxicam (7.5, 15 or 30 micromol/10 microl, i.t.), NS-398 (15 or 30 micromol), or L-NAME (30, 150 or 300 micromol) immediately before the nerve injury, followed by daily injection extending into the four postoperative days. The hindpaw was immersed into a hot (42 degrees C, 44 degrees C and 46 degrees C) or cold (10 degrees C) water bath. The paw immersion test revealed significant thermal hyperalgesia and allodynia 5 day after nerve injury in vehicle control animals. Tenoxicam (7.5, 15 or 30 micromol) or L-NAME (30, 150 or 300 micromol) dose-dependently attenuated hyperalgesia and allodynia. Equimolar dose of NS-398 (15 or 30 micromol) also diminished these nociceptive behaviors. Higher dose of either drug primarily produced longer duration of inhibition. The inhibitory effect of tenoxicam (30 micromol) on hyperalgesia was more effective than that of an equimolar dose of NS-398 or L-NAME. These results demonstrated that intrathecally administered COX inhibitor or NOS inhibitor provides preemptive analgesia on thermal hypersensitivity following chronic constrictive nerve injury in rats.

We conducted a randomized, placebo-controlled, double blinded study to compare the analgesic effects of intraarticular neostigmine, morphine, tenoxicam, clonidine and bupivacaine in 150 patients undergoing arthroscopic knee surgery. General anaesthesia protocol was same in all patients. At the end of the surgical procedure, patients were randomized into six intraarticular groups equally. Group N received 500 mug neostigmine, Group M received 2 mg morphine, Group T received 20 mg tenoxicam, Group C received 1 microg kg(-1) clonidine, Group B received 100 mg bupivacaine and Group S received saline 20 ml. Visual analog scale scores 0, 30 and 60 min and 2, 4, 6, 12, 24, 48 and 72 h, time to first analgesic need, analgesic consumption at 48 h and 72 h and side effects were noted. Demographic and operational parameters were similar in six groups. All study groups provided analgesia when compared with saline group (P<0.05). Duration of analgesia in Group N and C was longer than other groups (P<0.001). Analgesic consumptions of Group N, C and T were lower than other groups (P<0.01). Pain scores during 2 h postoperatively were lower in all study groups than the control group (P<0.001). In Group B, median pain scores were higher than Groups N and C at 0 min and 30 min postoperatively (P<0.001). Side effects were not significantly different among the six groups. We conclude that the most effective drugs that are administered intraarticularly are neostigmine and clonidine among the five drugs we studied. Tenoxicam provided longer analgesia when compared with morphine and bupivacaine, postoperatively.

A double-blind, randomized trial with placebo control was planned to evaluate the effects of corticosteroids (betamethasone, dexamethasone, methylprednisolone) in approximately equivalent doses (8 mg dexamethasone/day), and to compare their effects with that of tenoxicam, an antiinflammatory drug, on both the edema and ecchymosis in open rhinoplasty with osteotomies. For this study, 40 patients were divided randomly into five groups of 8 patients each, which received, respectively, betamethasone (group 1), dexamethasone (group 2), methylprednisolone (group 3), tenoxicam (group 4), and placebo (group 5). Open rhinoplasty with osteotomies was performed by the same surgeon with the patient under general anesthesia. Drugs were administered just before the induction of anesthesia and continued for 3 days. Only acetaminophen was used to control postoperative analgesia. Digital photographs of each patient were taken on postoperative days 1, 3, and 7. Scoring was performed separately for eyelid swelling and ecchymosis by three observers independently using a graded scale from 0 to 4. No statistically significant differences existed among the five groups in terms of age, sex, duration of surgery, amount of bleeding, and intravenous fluid administration during the surgery. On postoperative days 1, 3, and 7, no differences in the levels of ecchymosis or edema among the steroid groups, the tenoxicam group, and the control groups were observed. In conclusion, the authors observed no significant differences among the different kinds of steroids administered in equivalent doses (8 mg dexamethasone/day). Steroids used in these doses were not effective in preventing or reducing edema and ecchymosis after open rhinoplasty with osteotomies. Tenoxicam also was not effective. No complications caused by the use of steroids were observed during the 6-month follow-up period.
