Codeine phosphate in children: time for re-evaluation?

Its route of administration is usually oral or intramuscular (i.m.), although there is a growing interest in using the rectal route in children, from where it is rapidly absorbed, achieving a peak plasma concentration in 3060 min.1 In this recent study, a dose of codeine 1 mg kg1 given either rectally or i.m. in children over 3 months old produced a peak codeine level at 30 min, but with a consistently lower plasma level when given rectally. The lower plasma level after rectal administration reflects the reduced bioavailability of the drug when
