Chronic opioid consumption is associated with addiction, physical dependence, and tolerance. Tolerance results in dose escalation to maintain the desired effect. Intake of high‐dose or potent opioids may cause life‐threatening respiratory depression, an effect that be reduced by We performed a pharmacokinetic‐pharmacodynamic analysis effects fentanyl chronic users opioid‐naïve subjects quantify tolerance depression. Fourteen individuals eight received escalating doses intravenous...

Background Opioid-induced respiratory depression driven by ligand binding to mu-opioid receptors is a leading cause of opioid-related fatalities. Buprenorphine, partial agonist, binds with high affinity but displays effects. The authors examined whether sustained buprenorphine plasma concentrations similar those achieved some extended-release injections used treat opioid use disorder could reduce the frequency and magnitude fentanyl-induced depression. Methods In this two-period crossover,...

BACKGROUND. Potent synthetic opioids, such as fentanyl, are increasingly abused, resulting in unprecedented numbers of fatalities from respiratory depression. Treatment with the high-affinity mu-opioid receptor partial agonist buprenorphine may prevent by reducing binding potent opioids to opioid receptor, limiting

Data from low and middle-income countries (LMICs) on multidrug-resistant microorganisms (MDROs) in intensive care units (ICUs) are scarce. Working several ICUs Argentina, we sought to estimate the prevalence characteristics of MDRO infections carbapenemase-producing Enterobacterales (CPE) colonization. Mortality associated with infection was also evaluated. The study a 24-hour point conducted 164 adult Argentina between 24 November 28 2023. main outcome in-ICU mortality secondary outcomes...

RBP-6000 is a novel sustained-release formulation of buprenorphine for the treatment opioid use disorder, which has been designed once-monthly (28 days) subcutaneous (SC) injections. A population pharmacokinetic (PK) model was developed to describe time course plasma concentrations after repeated SC injections at 50 mg, 100 200 or 300 mg in treatment-seeking opioid-dependent subjects previously on sublingual (Subutex(®) ) treatment. The μ-opioid receptor occupancy predicted using PK/PD Emax...

The purpose of this study was to develop a whole-body physiologically based pharmacokinetic (WB-PBPK) model for ciprofloxacin ICU patients, on only plasma concentration data. In next step, tissue and organ time profiles in patients were predicted using the developed model. WB-PBPK built non-linear mixed effects approach data from 102 adult intensive care unit patients. Tissue distribution coefficients (Kp) available literature used as informative priors. successfully characterized both...

Purpose Area under the curve (AUC) dosing is routinely carried out for carboplatin, but chosen target AUC values remain largely empirical. This multicenter pharmacokinetic-pharmacodynamic (PK-PD) study was performed to determine covariates involved in interindividual variability of carboplatin hematotoxicity that should be considered when choosing individual AUCs. Patients and Methods Three hundred eighty-three patients received as part established regimens. A semi-physiologic population...
