The influence of age on the distribution of morphine and morphine-3-glucuronide across the blood-brain barrier in sheep
BACKGROUND AND PURPOSE: The effect of age on the distribution of morphine and morphine-3-glucuronide (M3G) across the blood-brain barrier (BBB) was studied in a sheep model utilizing intracerebral microdialysis. The effect of neonatal asphyxia on brain drug distribution was also studied.EXPERIMENTAL APPROACH: Microdialysis probes were inserted into the cortex, striatum and blood of 11 lambs (127 g
