Morphine and morphine-glucuronide concentrations in plasma and CSF during long-term administration of oral morphine.
Concentrations of morphine, morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G) were measured by h.p.l.c. in plasma and cerebrospinal fluid (CSF) samples from 16 patients with cancer receiving oral (controlled-release) morphine. There was a close correlation between plasma and CSF morphine concentrations (r = 0.94, P = 0.0001) and both correlated with drug dosage (r = 0.61, P = 0.013 ...
متن کاملRelative contribution of morphine and morphine-6-glucuronide to the analgesic effect after morphine administration.
Editor—We thank Dahan and Lotsch for their interest in our review and their valuable comments to the discussion about the role of morphine-6glucuronide (M6G), for the analgesic effect after morphine administration. Because morphine is used worldwide as the potent standard analgesic drug, with the formation of an even more potent metaboliteM6G, it is important to elucidate the relative contribut...
متن کاملDriving and intrathecal morphine administration.
Since Belgian law recently set a limit to morphine concentration detectable in blood and urine while driving a vehicle, questions arose about the implications for the medical use of opiates. We determined morphine concentrations in whole blood and urine by gas chromatography-mass spectrometry in 15 patients on continuous intrathecal morphine administration. Effects on blood and urine concentrat...
متن کاملMorphine Decreases Clopidogrel€Concentrations and Effects
Results M orphine injection delayed clopidogrel absorption (p 1⁄4 0.025) and reduced the area under the curve levels of its active metabolite by 34% (p 1⁄4 0.001). Morphine delayed the maximal inhibition of platelet aggregation on average by 2 h (n 1⁄4 24; p < 0.001). Residual platelet aggregation was higher 1 to 4 h after morphine injection (n 1⁄4 24; p < 0.005). Furthermore, morphine delayed ...
متن کاملDay-to-day variations during clinical drug monitoring of morphine, morphine-3-glucuronide and morphine-6-glucuronide serum concentrations in cancer patients. A prospective observational study
BACKGROUND The feasibility of drug monitoring of serum concentrations of morphine, morphine-6-glucuronide (M6G) and morphine-3-glucuronide (M3G) during chronic morphine therapy is not established. One important factor relevant to drug monitoring is to what extent morphine, M6G and M3G serum concentrations fluctuate during stable morphine treatment. METHODS We included twenty-nine patients adm...
