In this study 50 samples of ecstasy tablets seized in Iran during the period of 2007 through 2008 were examined and their physical characteristics (appearance, marking, scored/not scored, color, weight, diameter, thickness) were determined. In order to determine the chemical characteristics of these tablets, color tests (Marquis test, Simon’s test, Chen’s test and Gallic acid test), Thin Layer ...

BACKGROUND Despite the well-known fact that antibiotics (AB) are not effective against viruses, many patients ask for - and all too often doctors provide - AB for treating URTIs. Over-prescribing of AB is one of the key causes for the development of bacterial resistance, which the U.S. Centers for Disease Control and Prevention (CDC) calls "one of the world's most pressing public health problem...

The Drug Enforcement Administration (DEA) is required, as part of the Methamphetamine Epidemic Elimination Act, to develop annual quotas for the manufacture and importation of ephedrine, pseudoephedrine, and phenylpropanolamine products for legitimate utilization in the U.S. At DEA’s request, IMS Health (IMS) identified an approach for generating estimates of 2005 usage for ephedrine and pseudo...

A 68-year-old man presented with a generalized papular eruption with oedema of the face and the hands, fever and pustulosis in intertriginous areas which had begun 1 day after starting treatment with EuvanolA nasal spray (plant extracts and benzalkonium chloride) and DolirhumA (paracetamol and pseudoephedrine). He has been hospitalized 8 years before for a similar eruption associated with hyper...

Pseudoephedrine is frequently used as a decongestant. Because of concern about the safety of pseudoephedrine in hypertensive patients, a clinical trial was conducted to determine whether blood pressure control was actually affected by this drug in a selected group of patients with hypertension. Twenty-nine patients with controlled, uncomplicated hypertension, who received drug therapy and range...

A Stability indicating reverse phase high performance liquid chromatographic method has been developed for the simultaneous determination of Levocetirizine dihydrochloride and Pseudoephedrine sulfate in pharmaceutical formulation. The mobile phase A consisted of Potassium dihydrogen phosphate Buffer 0.05M and 1-Ocatne sulphonic acid sodium salt 0.25%, pH adjusted to 3.0 with orthophospheric aci...

A rapid and sensitive CZE (Capillary Zone Electrophoresis) method for pharmaceutical analysis was developed and fully validated. The active compounds: Pseudoephedrine hydrochloride (PSE), Triprolidine hydrochloride (TRI) and Paracetamol (PAR) were separated and quantitatively determined using the tris-borate 30 mM buffer at pH = 9.0 as a Background Electrolyte (BGE). The electrophoretic separat...

INTRODUCTION Neurologic consequences of manganese toxicity have been recognized since 1837. A new form of presumed manganese poisoning has been reported in drug-addicted persons from Eastern Europe and the Baltic states who have intravenously injected self-prepared methcathinone hydrochloride (ephedrone), which is synthesized from pseudoephedrine hydrochloride using potassium permanganate as a ...

Ephedra have been used as a common traditional Chinese medicine for thousands of years. However, the perspiration effect of the unprocessed ephedra was too strong. Clinical trials have shown that processing methods play a critical role in moderating the perspiration property of ephedra according to the needs. A LC-MS/MS method was developed and validated to compare the pharmacokinetic propertie...

This study was designed to optimize a method for the identification and quantification of ephedrines in oral fluid (OF) and for its application to subjects taking different doses of pseudoephedrine. Ephedrines use by athletes is banned by World Anti-Doping Agency (WADA), only "in competition" if their concentration in urine exceeds the cutoff limit. The study aimed to establish if there is a co...
