Pseudoephedrine (PSE) salts (hydrochloride and sulfate) are commonly used as nasal and paranasal decongestants by scuba divers. Anecdotal reports from the Divers Alert Network suggest that taking PSE prior to diving while breathing pure O₂ increases the risk for CNS oxygen toxicity (CNS-OT), which
BACKGROUND
Clandestine laboratory operators commonly extract ephedrine and pseudoephedrine-precursor chemicals used to synthesize methamphetamine-from over-the-counter cold/allergy/sinus products. To prevent this activity, two states, Oregon in 07/2006 and Mississippi in 07/2010, implemented
OBJECTIVE
To study the action of pseudoephedrine salicylate on the central nervous system of mice.
METHODS
Following the administration of pseudoephedrine salicylate at various dose levels and schedules, the alterations in general behavior and autonomic activities of the mice were recorded using
A follow-up study of over 100,000 persons below age 65 years who filled a total of 243,286 prescriptions for pseudoephedrine indicated that there were no hospitalizations among users that could be attributed to the drug. There were no admissions within 15 days of filling a prescription for
OBJECTIVE
Pseudoephedrine is a precursor often diverted into the illegal manufacture of amphetamine type substances (ATS). The aim of this study was to evaluate the effectiveness of a linked electronic medication recording system (LEMS) established in Australian pharmacies in 2005 for preventing the
In-silico optimised two-dimensional high performance liquid chromatographic (2D-HPLC) separations of a model methamphetamine seizure sample are described, where an excellent match between simulated and real separations was observed. Targeted separation of model compounds was completed with
Nineteen crystalline methamphetamine ('ice') seizures captured by the Australian Federal Police (AFP) at the Australian border between 1998 and 2002 were analysed. Using a modified gas chromatograph-mass spectrometry (GC-MS) impurity profiling approach of these samples we have identified >30
In-silico optimisation of a two-dimensional high performance liquid chromatography (2D-HPLC) separation protocol has been developed for the interrogation of methamphetamine samples including model, real world seizure, and laboratory synthesised samples. The protocol used Drylab(®) software to
Ephedrine/pseudoephedrine (EPH) is the most common precursor for the manufacture of methamphetamine and is controlled within China via criminal law and government regulations. Therefore, it is of great significance to systematically study the cases of illicit production of EPH in order to aid timely
A GC-MS method has been developed for the detection of amphetamine, methamphetamine, and the ephedrines, in seizures and the urine, based on on-GC condensation (derivatization) with cyclohexanone. The method is simple: the dried seizure material or the urine extract was mixed with cyclohexanone and
A method for simultaneous enantiomeric separation of ephedrine, pseudoephedrine, and methamphetamine (MA) in a single run by simple capillary zone electrophoresis (CZE) with beta-cyclodextrin as a chiral selector is described. The effects of the buffer pH, phosphate concentration, beta-cyclodextrin
Forensic intelligence of synthetic illicit drugs suffers a problem of continuous introduction of new synthetic methods, modification of the existing routes of manufacture, and adulterations practiced by criminal networks. Impurity profiling has been indispensable in methamphetamine intelligence
Methamphetamine is a highly addictive drug that is created illegally in clandestine laboratories using a variety of household chemicals, including ephedrine or pseudoephedrine, that is extracted from over the counter medications.1 There is no legally available alternative drug.
An intravenously injectable illicit drug made by mixing pseudoephedrine, potassium permanganate, vinegar and water, yielding methcathinone (Mcat) and manganese (Mn), induces an extrapyramidal syndrome with parkinsonism, dystonia, gait and balance disorders similar to manganism. Although the cause of
