Pseudoephedrine is a tough product to challenge as a nasal decongestant

Although pseudoephedrine has had its fair share of negative publicity in recent years, Jenny Bryan looks at why it is still one of the best decongestants around

Praise again for pharmacy over successful pseudoephedrine controls

Pharmacists have once again been thanked for making a “substantial contribution” to managing the potential misuse of medicines containing pseudoephedrine and ephedrine...

The AAPS Journal: Regional-Dependent Intestinal Permeability and BCS Classification: Elucidation of pH-Related Complexity in Rats Using Pseudoephedrine

Type: Original PaperBased on its lower Log P value relative to metoprolol, a marker for the low/high-permeability (Peff) class boundary, pseudoephedrine was provisionally classified as BCS low-permeab...

Proliferation of 'Meth Labs' Linked to Pseudoephedrine Sales

A rise in pseudoephedrine sales has been linked to a corresponding increase in the proliferation of clandestine methamphetamine laboratories, a new study shows. Medscape Medical News

Polycystic kidney disease: An early urea-selective urine-concentrating defect in ADPKD

A defect in urine-concentrating ability is discernable in patients with autosomal dominant polycystic kidney disease (ADPKD) before any decline in glomerular filtration rate, and is associated with el...

Pseudoephedrine Sales and Seizures of Clandestine Methamphetamine Laboratories in Kentucky

To the Editor: The illicit production of methamphetamine from the precursor pseudoephedrine in clandestine laboratories fuels up to 35% of the domestic supply. Public health, law enforcement, and medi...

Simple and accurate quantitative analysis of seven prohibited threshold substances in human urine by liquid chromatography/tandem mass spectrometry in doping control.

A simple and accurate liquid chromatography/tandem mass spectrometry (LC/MS/MS) method has been developed and validated for the quantitative determination of ephedrine, pseudoephedrine, methylephedrin...

Lab-on-a-chip screening of methamphetamine and pseudoephedrine in samples from clandestine laboratories.

The clandestine manufacture of methamphetamine in New Zealand predominantly involves the reduction of pseudoephedrine, extracted from pharmaceutical preparations, using hydrogen iodide. This method of...

Determination of urinary concentrations of pseudoephedrine and cathine after therapeutic administration of pseudoephedrine-containing medications to healthy subjects: implications for doping control analysis of these stimulants banned in sport.

Due to its stimulatory effects on the central nervous system, and its structural similarity to banned stimulants such as ephedrine and methamphetamine, pseudoephedrine (PSE) at high doses is considere...
