serious toxicity other than some nausea. Continued treatment with intravenous theophylline resulted in compensation of her respiratory difficulties. In its literature, Clinical Assays mentions that 8-chlorotheophylline may interfere. Dimenhydrinate is the 8chlorotheophylline salt of the antihistaminic diphenhydrammne. In addition to the theophylline peak on chromatography, there was another pea...

Anaphylaxis Associated with Peanuts and Nuts in Late Mexican Adolescents: A Population Based Study

Background: There is a lack of information regarding anaphylaxis that is triggered by the peanut and nuts in countries with emerging economies. We aimed to identify the factors that are related to the prevalence of secondary anaphylaxis that results from ingesting peanuts or nuts. Materials and Methods: A cross-sectional, population-based study was conducted in which we applied a structured qu...

Application of Chemometrics in Simultaneous Spectrophotometric Quantification of Etophylline and Theophylline: The Drugs with Same Chromophore

Chemometric techniques in spectral analysis have gained importance in the quality control of  the drugs mixtures and pharmaceutical formulations containing two or more drugs with overlapping spectra. Since theophylline and etophylline have common chromophore, they cannot be analyzed simultaneously using conventional UV methods. Simultaneous spectrophotometric determination of etophylline and th...

Urticaria caused by dimenhydrinate.

Effect of adenosine on histamine release and atrioventricular conduction during guinea pig cardiac anaphylaxis.

Anaphylactic events occurring in cardiac tissue can result in severe metabolic imbalances. The present study addresses the question of whether adenosine, produced in response to this stress, influences either the antigen-antibody-induced alterations in cardiac function or the release of histamine, which is known to be one of the important mediators of the anaphylactic reaction. Isolated hearts ...
