Neurological Adverse Effects Associated With Commonly Used H1‐Antihistamines: A Narrative Review of Age‐Stratified Risk Profiles in Paediatric and Geriatric Populations

open access: yesMedicine Advances, EarlyView.
This narrative review examines the neurological adverse effects associated with commonly used H1‐antihistamines, focusing on how blood–brain barrier (BBB) penetration and patient age influence central nervous system (CNS) toxicity. The major finding is that first‐generation antihistamines, because of higher CNS penetration, are associated with ...

Histamine analogues, XXXV: 2-substituted histamine derivatives containing classical moieties of H2-antagonists--a novel class of H1-agonists

open access: yes, 1993
A new type of H1-agonists resulted from the combination of the essential histamine structure with parts of H2-antagonists. 2,4-Disubstituted imidazole derivatives were synthesized by reaction of imidic acid methyl esters with 1,3-dihydroxypropanone, 1,4 ...

A Novel Membrane Sensor for Histamine H1-Receptor Antagonist “Fexofenadine”

open access: yesAnalytical Sciences, 2004
The construction and general performance of thirteen new polymeric membrane sensors for the determination of fexofenadine hydrochloride based on its ion exchange with reineckate, tetraphenylborate and tetraiodomercurate have been studied. The effects of membrane composition, type of plasticizer, pH value of sample solution and concentration of the ...

Investigations on neuropeptide Y and histamine receptors by fluorescence-based and radiochemical methods [PDF]

open access: yes, 2011
In the last three decades, a large amount of experimental data (for example Förster resonance energy transfer (FRET) at fluorescently labelled receptors) supported the hypothesis of the dimerization of G-protein-coupled receptors (GPCR), including ...

Pharmacokinetic and Pharmacodynamic Interactions Between Anti‐Asthma Drugs and Medicinal Plants: A Comprehensive Review

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Asthma affects 260–300 million people worldwide. About 20%–35% of patients use medicinal plants with their asthma medication, often without telling their clinicians. Disclosure rates are low; up to 42% of asthma outpatients use herbal products, with no records in their charts.

Novel Bispecific Engagers Targeting the CεmX Domain of mIgE‐Expressing Cells

open access: yesAllergy, EarlyView.
We developed bispecific TCE & NKCE targeting the CεmX domain of mIgE to eliminate IgE‐producing cells. Both constructs demonstrated potent, specific, dose‐dependent cytotoxicity and selective immune activation in vitro. These results highlight their promise as off‐the‐shelf, potentially curative therapeutics for IgE‐associated allergic diseases ...
