Codeine-6-glucuronide (C6G) is a major active metabolite of codeine and as such is the molecule responsible for as much as 60% of the analgesic effects of codeine. C6G exhibits decreased immunosuppressive effects compared to codeine.^[1] During its metabolism, codeine is conjugated with glucuronic acid by the enzyme UDP-Glucuronosyltransferase-2B7 (UGT2B7) to form codeine-6-glucuronide.^[2]
