摘要

Background and Objectives: The aims of this study were to establish the potencies of epinephrine, bupivacaine, dextromethorphan, 3-methoxymorphinan, and dextrorphan and evaluate interactions of epinephrine with bupivacaine, dextromethorphan, 3-methoxymorphinan, or dextrorphan as an infiltrative anesthetic. Bupivacaine, a common and long-acting local anesthetic, was used as control. Methods: Dose-dependent responses of epinephrine, dextromethorphan, 3-methoxymorphinan, and dextrorphan on cutaneous analgesia were compared with bupivacaine in rats. The interactions of drugs were evaluated via an isobolographic analysis. Results: We found that epinephrine, bupivacaine, dextromethorphan, 3-methoxymorphinan, and dextrorphan produced a dose-dependent local anesthetic effect as infiltrative cutaneous analgesia. Relative potencies were epinephrine > bupivacaine > dextromethorphan > 3-methoxymorphinan > dextrorphan (P < .01 for each comparison). Coadministration of bupivacaine with epinephrine produced a synergistic effect, and coadministration of dextromethorphan, 3-methoxymorphinan, or dextrorphan with epinephrine produced an additive effect. Conclusions: Epinephrine, dextromethorphan, 3-methoxymorphinan, and dextrorphan are known to have local anesthetic effects as infiltrative cutaneous analgesia in rats. Epinephrine increased the potency of bupivacaine, but not dextromethorphan, 3-methoxymorphinan, or dextrorphan as an infiltrative anesthetic. The cutaneous analgesic effects of adding epinephrine to dextromethorphan, 3-methoxymorphinan, or dextrorphan, are similar to combinations of 2 local anesthetics.
