Simultaneous determination of parecoxib and its main metabolites valdecoxib and hydroxylated valdecoxib in mouse plasma with a sensitive LC–MS/MS method to elucidate the decreased drug metabolism of tumor bearing mice

In this study, a sensitive, rapid and specific LC–MS/MS method for quantification of PX, VX and OH-VX in the plasma of tumor bearing mouse was developed and validated. After protein precipitation, all the analytes were separated on an Agilent ZORBAX Extend-C18 HPLC column (2.1 × 100 mm, 3.5 μm) with gradient elution. The analytes were detected by an electrospray negative ionization mass spectrometry in the multiple reaction monitoring mode. The transition m/z 369.0 → 119.0, m/z 312.9 → 117.9, m/z 329.0 → 196.0, and m/z 307.1 → 161.3 were used for monitoring PX, VX, OH-VX and IS respectively. The calibration curves of the analytes showed good linearity over the concentration range of 3–3000 ng/mL for PX and VX, and 3–1000 ng/mL for OH-VX. Intra- and inter-batch accuracies (in terms of relative error, RE

CONCLUSION: These findings have significant opioid policy and practice implications related to the need for cancer-specific prescribing guidelines, how to optimally allocate health delivery services, and the urgent need to improve data interoperability and access related to POMs. PMID: 31682546 [PubMed - as supplied by publisher]

Abstract Chronic pain, stemming primarily from musculoskeletal conditions and severe headaches, is a growing problem in the United States, affecting as many as 43% of adults. Opioids are frequently prescribed to manage chronic pain despite limited data on their long-term efficacy and the potential risks of long-term use. In 2017, more than 47,000 people died as a result of an opioid overdose involving illicit opioids (such as heroin), illicitly manufactured opioids, diverted opioids, prescription opioids, or some combination thereof. Although it's been more than three years since the nationwide opioid crisis promp...

CONCLUSIONS: Some degree of dependence was present across both addiction and pain clinic groups, supporting the notion a state of dependence can be identified among chronic pain patients taking opioids long term. Aberrant behaviors were not common in the pain clinic sample, suggesting these patients are unlikely to meet Diagnostic and Statistical Manual of Mental Disorders-V criteria for Substance Use Disorder. However, opioid dependence carries significant risks for relapse, chronicity, morbidity and mortality, warranting specific medical management. Management of such risks should be considered routine care in chronic pa...

AbstractThe primary objective of this article is to assist oncologists and advanced practice prescribers to safely and effectively minimize risk when providing opioids for cancer pain relief. The majority of people with cancer are unlikely to misuse or divert opioid medications, yet the prescriber is often unaware of those who are at risk for these behaviors. To provide skillful pain management to each patient in the oncology setting, while limiting harm to the community, all prescribers must consider the potential for risk of misuse, addiction, or diversion. To minimize this risk to the greatest degree possible, it is imp...

The working title of these series of posts was in fact “Goddamned Opioids and the Goddamned Opioid Crisis’ because it’s a confusing time out there. A lot of us in palliative care have watched the unfolding, devastating, opioid overdose crisis in the US with dread and horror, as well as th...

The U.S. Centers for Disease Control and Prevention is investigating a growing number of “severe” lung disease cases that appear to be related to vaping. Since late June, according to the CDC, 94 people in 14 states have come down with serious lung illnesses that may be linked to use of e-cigarettes, which heat substances including nicotine and cannabis to create aerosols that users inhale. The case count has grown high enough to prompt the CDC to work with state health departments to learn more about what could be causing the worrisome conditions, which are primarily affecting adolescents. Although “mor...
