Examples of full agonists are oxycodone, methadone, codeine, heroin and morphine. PARTIAL AGONISTS. Partial agonists are drugs that bind primarily to mu opioid receptors and cause them to produce endorphins but to a much lesser extent than full agonists. BuprenorphineÂ®, SuboxoneÂ® and SubutexÂ® are partial agonists.
Codeine sulfate is an opioid analgesic, related to morphine, but with less potent analgesic properties. Chemically, codeine is Morphinan-6-ol,7,8-didehydro-4,5-epoxy-3-methoxy-17-methyl-(5Î±,6Î±)-, sulfate (2:1) (salt), trihydrate.Its empirical formula is C 18 H 21 NO 3 and its molecular weight is 299.36.etabolism. About 70-80% of administered dose of codeine is metabolized by conjugation with glucuronic acid to codeine-6glucuronide (C6G) and via O-demethylation to morphine (about 5-10%) and N-demethylation to norcodeine (about 10%) respectively.
