Analgesic and anti-inflammatory efficacy of tenoxicam and diclofenac sodium after third molar surgery.
Tenoxicam and diclofenac sodium were compared with each other for analgesic efficacy following removal of third molars under general anesthesia. Thirty-five healthy patients between the ages of 18 and 28 yr were randomly allocated to two groups to participate in this study. Patients in Group A (n = 17) received a single intravenous injection of tenoxicam 40 mg at induction of anesthesia, followed by a 20-mg tablet given in the evening of the day of the operation and thereafter, one 20-mg tablet daily from days 2 to 7. Group B (n = 18) received a single intramuscular injection of diclofenac sodium 75 mg at induction of anesthesia, followed by a 50-mg tablet 4 to 6 hr after the operation and again, between 2100 hr and 2200 hr the same day. Thereafter, a 50-mg tablet was taken 3 times daily for the next 6 days. Pain was measured hourly for the first 4 hr postoperatively, then at 21 hr, and thereafter in the morning and the evenings on days 2 to 7. The highest pain scores were obtained 1 hr postoperatively for both trial groups. At 1 and 2 hr postoperatively, no statistical significant differences in pain scores could be shown for both groups. However, at 3 and 4 hr postoperatively, patients in the tenoxicam group experienced significantly (P < or = 0.05) less pain than those in the diclofenac sodium group. On the evening of the third postoperative day, the tenoxicam group of patients experienced significantly less pain (P < or = 0.05) than those in the diclofenac sodium group. This was again the case on the morning of the fourth postoperative day. On the fifth, sixth, and seventh postoperative days, the average pain scores for patients in the tenoxicam group were statistically significantly lower, both mornings and evenings, than those in the diclofenac sodium group of patients (P = 0.05).
