Plasticity of histamine H3 receptor expression and binding in the vestibular nuclei after labyrinthectomy in rat [PDF]

open access: yes, 2004
Background: In rat, deafferentation of one labyrinth (unilateral labyrinthectomy) results in a characteristic syndrome of ocular and motor postural disorders (e.g., barrel rotation, circling behavior, and spontaneous nystagmus). Behavioral recovery (e.g.,

The relation between antihistamine medication during early pregnancy & birth defects

open access: yesEgyptian Journal of Medical Human Genetics, 2015
Antihistamines are a group of medications which can inhibit various histaminic actions at one of two histamine receptors (H1 or H2). H1 receptor antagonists are used for the relief of allergic dermatological and nondermatological conditions.

Clozapine:norclozapine ratio as a marker of metabolic risk and therapeutic response and effect of valproate on clozapine levels

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Clozapine is the most effective antipsychotic in treatment‐resistant schizophrenia. Clozapine causes weight gain and increased diabetes risk. The role of its metabolite norclozapine and clozapine:norclozapine ratio (CLZ/NCLZ) in metabolic effects has been debated.

Effect of histamine H1 and H2 receptor antagonists on histamine-induced macrophage LOX-1 mRNA expression.

open access: yes, 2014
Monocyte-derived macrophages were incubated in the presence of 10 µM histamine and the indicated concentrations of the histamine H1 and H2 receptor antagonists (pyrilamine and ranitidine, respectively) for 4 h and analyzed for LOX-1 mRNA expression.

Histamine and the mechanisms of nausea and vomiting: Translating the uncertain pharmacology of cyclizine

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Cyclizine is a long‐established, short‐acting drug, registered for preventing motion sickness, post‐operative nausea and vomiting (PONV) and ‘vomiting of known cause’. The latter is not defined but may include pregnancy and patients receiving palliative care, historically accepted without large, controlled trials.

Typical and Atypical Antipsychotic Drugs Increase Extracellular Histamine Levels in the Rat Medial Prefrontal Cortex: Contribution of Histamine H1 Receptor Blockade

open access: yesFrontiers in Psychiatry, 2012
Atypical antipsychotics such as clozapine and olanzapine have been shown to enhance histamine turnover and this effect has been hypothesized to contribute to their improved therapeutic profile compared to typical antipsychotics.

The potential impact of H1 antihistamines on clinical outcomes in NSCLC patients undergoing EGFR‐TKIs treatment

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Background Epidermal growth factor receptor–tyrosine kinase inhibitors (EGFR‐TKIs) have substantially improved outcomes in non‐small cell lung cancer (NSCLC); however, the development of treatment resistance remains a major clinical challenge. This study examines the association between concomitant prescriptions of H1‐antihistamines (H1AHs) and ...

Antihistamines in the treatment of allergic diseases: not as simple as it seems!

open access: yesКлинический разбор в общей медицине, 2023
According to WHO, up to 35% of the world's population suffers from allergic diseases, and this number is growing exponentially. Histamine has been proven to play a key physiological role in the pathogenesis of allergic disorders by affecting tissues ...
