Diffusion of Carbamazepine in Hydrophobic Zeolites: A Comparative Study Using Classical and Machine‐Learned Potentials

Chemistry – A European Journal, EarlyView.
Can hydrophobic, shape‐selective zeolites efficiently remove the persistent pharmaceutical CBZ from water? This work moves beyond the static picture of interaction energies by modeling diffusion with umbrella sampling and machine‐learned potentials. Even high intrinsic diffusion barriers can be overcome through exergonic adsorption from water, yielding

Drug Critical Limits for Urgent Physician Notification

Clinical Pharmacology &Therapeutics, EarlyView.
Critical limits represent quantitative decision thresholds for drugs that require immediate clinician notification and potential life‐saving intervention. United States hospitals lack a national standard for drug critical limits. We collected critical limits from 417 US hospitals across all 50 states and Washington, D.C.; of these, 411 maintained drug ...

Effect of Reaction Time and Temperature on the Impurity Profile of Amphetamine in the Leuckart Method

Drug Testing and Analysis, EarlyView.
This study investigates the effect of the reaction temperature (step 1) and reaction time (step 1 and 2) on the conversion efficiency and impurity profile of amphetamine synthesized via the Leuckart method. Conversion efficiency and impurity profile were assessed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (GC ...

Identification and Characterization of the Designer Opioid N‐Pyrrolidino Fluetonitazene in Nasal Spray

Drug Testing and Analysis, EarlyView.
N‐Pyrrolidino fluetonitazene, a synthetic opioid, was identified and characterized in a nasal spray using GC‐MS, LC‐QTOF‐MS, NMR and FT‐IR. ABSTRACT Detection of drugs in non‐biological samples serves as a fundamental basis for identifying emerging trends in the field of new psychoactive substances and provides valuable information for optimizing ...
