is codeine a vasodilator
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.
