Responding in rats was maintained under a fixed-ratio 30 schedule of food presentation. When administered acutely buprenorphine (0.018-0.56 mg/kg) produced dose-related decreases in overall rate of responding. In addition to schedule-controlled behavior, the analgesic effects of buprenorphine were evaluated during chronic administration using the tail-flick method. Tolerance developed to the effects of buprenorphine on both measures. In general dose-effect curves for the rate-decreasing effects of buprenorphine were shifted to the right by approximately 2 log units. In one subject, however, tolerance did not develop to the rate-decreasing effects of 10 mg/kg, suggesting that behavioral tolerance to buprenorphine is dose limited. Finally, the data also suggested that tolerance may develop more slowly, yet more completely, to the analgesic than to the rate-decreasing effects of buprenorphine.

D012055	Reinforcement Schedule	A schedule prescribing when the subject is to be reinforced or rewarded in terms of temporal interval in psychological experiments. The schedule may be continuous or intermittent.	Reinforcement Schedules,Schedule, Reinforcement,Schedules, Reinforcement
D002047	Buprenorphine	A derivative of the opioid alkaloid THEBAINE that is a more potent and longer lasting analgesic than MORPHINE. It appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. The lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use.	6029-M,Buprenex,Buprenorphine Hydrochloride,Buprex,Prefin,RX-6029-M,Subutex,Temgesic,Temgésic,6029 M,6029M,Hydrochloride, Buprenorphine,RX 6029 M,RX6029M

D004361	Drug Tolerance	Progressive diminution of the susceptibility of a human or animal to the effects of a drug, resulting from its continued administration. It should be differentiated from DRUG RESISTANCE wherein an organism, disease, or tissue fails to respond to the intended effectiveness of a chemical or drug. It should also be differentiated from MAXIMUM TOLERATED DOSE and NO-OBSERVED-ADVERSE-EFFECT LEVEL.	Drug Tolerances,Tolerance, Drug,Tolerances, Drug
