talwin-nx and Pain--Postoperative

Pentazocine can be a useful analgesic agent for the management of acute dental pain. It has both central and peripheral opioid activity. In clinical trials, analgesic compounds containing pentazocine have been shown to effectively relieve moderate-to-severe pain. It is an appropriate analgesic for the codeine-sensitive patient. Because of a change in formulation, the potential for abuse has been minimized. Although there is a possibility that the drug may have a psychotomimetic effect, the incidence is low and should not preclude use. Analgesic compounds containing pentazocine are clinically appropriate for the management of surgically induced dental pain.

The purpose of this prospective clinical trial was to investigate the analgesic efficacy of three oral medication groups on postoperative endodontic pain in male and female dental patients, with an emphasis on analgesic differences between the sexes. Forty-three patients were administered ibuprofen 600 mg, placebo, or pentazocine 50 mg/0.5 mg naloxone in a randomized, double-blinded manner. Beginning immediately after endodontic treatment, patients took the assigned medication every 6 hours for 24 hours and recorded their degree of discomfort on a 100-mm visual analog scale. Statistical analysis of the data showed that ibuprofen 600 mg provided statistically significantly greater analgesia than placebo at 6 and 12 hours (P = 0.0014 and 0.0024), and pentazocine/naloxone provided statistically significantly greater analgesia than placebo at 12 hours (P = 0.0084). Sex-dependent differences were noted within the pentazocine/naloxone group, which showed significantly greater analgesia in females compared with males (P = 0.007).
