Dose-response curves were constructed for the individual administration of haloperidol, buprenorphine, and tramadol in rats subjected to the formalin (1%) test. All the compounds demonstrated dose-dependent antinociceptive effects when administered individually. Pharmacological interactions were assessed using an isobolographic method. The doses required to achieve 50% of the maximal antinociceptive effect (ED50) for each drug were combined at a fixed 1 : 1 ratio to establish a combination series of haloperidol + buprenorphine and haloperidol + tramadol. The results showed that buprenorphine achieved a higher maximal antinociceptive effect (98%) compared with tramadol (85%) and haloperidol (84.9%) when administered individually. Isobolographic analysis revealed that the experimental values (Zexp) for haloperidol + buprenorphine (Zadd = 27.6 ± 5.5 vs. Zexp = 5.47 ± 1.2) and haloperidol + tramadol (Zadd = 4987.68 ± 651.5 vs. Zexp = 1678.23 ± 89.8) were significantly lower than the theoretical values (Zadd), indicating synergistic interactions. On the basis of the experimental data, haloperidol potentiated the antinociception in the following order: haloperidol + buprenorphine, followed by haloperidol + tramadol. These findings suggest that such drug combinations could have potential applications in the ongoing research of treatments for chronic pain, depression-related pain, and cancer-associated pain.</p>","PeriodicalId":8832,"journal":{"name":"Behavioural Pharmacology","volume":"36 7","pages":"517-525"},"PeriodicalIF":1.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
