Since these compounds are respiratory depressants as well, concern has been expressed that the use of narcotic antagonists as analgesics would be handicapped by the lack of an antagonist to its toxic effects, especially respiratory depression. This study was undertaken to demonstrate that a nonspecific analeptic could antagonize the respiratory depression induced by a narcotic antagonist. The respiratory depressant effects of pentazocine, a weak narcotic antagonist which is a potent nanaddicting analgesic in man, was used as the test object. Methylphenidate (30 mg. per 70 Kg. intravenously) significantly antagonized the respiratory depression of pentazocine (40 mg. per 70 Kg. intramuscularly) compared to a placebo in a complete crossover study of six healthy subjects. Antagonism was incomplete at 30 minutes but almost complete at 75 minutes after methylphenidate.<\/jats:p>","DOI":"10.1002\/cpt19656112","type":"journal-article","created":{"date-parts":[[2016,1,5]],"date-time":"2016-01-05T00:37:43Z","timestamp":1451954263000},"page":"12-16","source":"Crossref","is-referenced-by-count":9,"title":["Studies of analgesic drugs"],"prefix":"10.1111","volume":"6","author":[{"given":"Jane","family":"Telford","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arthur S.","family":"Keats","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,1,4]]},"container-title":["Clinical Pharmacology &amp; Therapeutics"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fcpt19656112","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fcpt19656112","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ascpt.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/cpt19656112","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,7]],"date-time":"2023-11-07T13:34:13Z","timestamp":1699364053000},"score":1,"resource":{"primary":{"URL":"https:\/\/ascpt.onlinelibrary.wiley.com\/doi\/10.1002\/cpt19656112"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1965,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1965,1]]}},"alternative-id":["10.1002\/cpt19656112"],"URL":"https:\/\/doi.org\/10.1002\/cpt19656112","archive":["Portico"],"relation":{},"ISSN":["0009-9236","1532-6535"],"issn-type":[{"value":"0009-9236","type":"print"},{"value":"1532-6535","type":"electronic"}],"subject":[],"published":{"date-parts":[[1965,1]]}}}
