A mixture of acetaminophen, diphenhydramine hydrochloride and pseudoephedrine hydrochloride is used for the symptomatic treatment of common cold. In this study, a derivative spectrophotometric method based on zero-crossing technique was proposed for simultaneous determination of acetaminophen, diphenhydramine hydrochloride and pseudoephedrine hydrochloride. Determination of these drugs was perf...

The histamine I receptor antagonist diphenhydramine is a freely available, over the counter medication for sleep and the most frequently used antihistamine drug. It inhibits the fast sodium channels and, at higher concentrations, the repolarising potassium channels, particularly Ikr which leads to prolongation of the action potential and the QT interval. The toxicity of diphenhydramine is dose-...

A fatal poisoning case involving multiple psychotropic drugs is presented. Quantitative toxicological analysis showed that the concentrations of diphenhydramine, paroxetine, phenobarbital, diazepam and its metabolites (nordiazepam and temazepam) in the femoral blood were 9.19 μg/ml, 1.02 μg/ml, 19.9 μg/ml, 0.26 μg/ml, 8.55 μg/ml and 2.69 μg/ml, respectively. We concluded that the cause of death...

Cloperastine is an antitussive drug, which can be received as an over-the-counter cold medicine. The chemical structure of cloperastine is quite similar to that of the antihistamine drug diphenhydramine, which is reported to inhibit hERG K⁺ channels and clinically induce long QT syndrome after overdose. To analyze its proarrhythmic potential, we compared effects of cloperastine and diphenhydram...

BACKGROUND We present the first full case report of the treatment of mast cell activation syndrome with continuous diphenhydramine infusion, which resulted in the improvement of anaphylactic reactions and a decrease in hospital readmission. Furthermore, the patient received imatinib in the absence of the KIT-D816V mutation, which led to further improvement of quality of life. Currently, we are ...

Abstract Background The urine immunochromatographic assay is a useful screening tool for patients suspected of acute drug intoxication in emergency conditions. Diphenhydramine shows symptoms similar to those tricyclic antidepressant (TCA) intoxication. Case presentation We examined case diphenhydramine showing cerebellar ataxia and prolonged false positive results TCA the urine. test showed per...
