Influence of Morbid Obesity on the Pharmacokinetics of Morphine, Morphine-3-Glucuronide, and Morphine-6-Glucuronide
INTRODUCTION Obesity is associated with many pathophysiological changes that may result in altered drug metabolism. The aim of this study is to investigate the influence of obesity on the pharmacokinetics of morphine, morphine-3-glucuronide (M3G), and morphine-6-glucuronide (M6G) through a combined analysis in morbidly obese patients and non-obese healthy volunteers. METHODS In this analysis,...
متن کاملPharmacokinetics of Morphine, Morphine-3-Glucuronide and Morphine-6-Glucuronide in Terminally Ill Adult Patients
BACKGROUND AND OBJECTIVE Morphine dosing can be challenging in terminally ill adult patients due to the heterogeneous nature of the population and the difficulty of accurately assessing pain during sedation. To determine the pharmacokinetics of morphine, morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G) in this population, and to find clinically relevant parameters for dose individu...
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 کاملIn search of a role for the morphine metabolite morphine-3-glucuronide.
M orphine is the most commonly used opioid analgesic, and while extremely effective in relieving moderate to severe acute pain, it produces a number of well-characterized, undesirable side effects that include respiratory depression, sedation, dysphoria, decreased gastric motility, nausea, and vomiting. These analgesic and unwanted actions of morphine are mediated predominately by -opioid recep...
متن کاملThe TLR4-Active Morphine Metabolite Morphine-3-Glucuronide Does Not Elicit Macrophage Classical Activation In Vitro
Macrophages are abundant in the tumor microenvironment where they adopt a pro-tumor phenotype following alternative polarization induced by paracrine factors from cancer and stromal cells. In contrast, classically activated macrophages have tumoricidal activities, such that the polarization of tumor-associated macrophages has become a novel therapeutic target. Toll-like receptor 4 engagement pr...
