BACKGROUND It has been proposed that the histamine 1-receptor (H1-receptor) not only promotes allergic reactions, but also modulates innate immunity and autoimmune reactions. In line with this, we have recently reported that the H1-receptor antagonist cetirizine partially counteracts cytokine-induced beta-cell signaling and destruction. Therefore, the aim of this study was to determine whether ...

The intercalation of cetirizine into two types of layered double hydroxides, Zn/Al and Mg/Al, has been investigated by the ion exchange method to form CTZAN and CTMAN nanocomposites, respectively. The basal spacing of the nanocomposites were expanded to 31.9 Å for CTZAN and 31.2 Å for CTMAN, suggesting that cetirizine anion was intercalated into Layered double hydroxides (LDHs) and arranged in ...

PURPOSE P-glycoprotein (P-gp) plays a major role in oral absorption of drugs. Induction or inhibition of P-gp by drugs contributes to variability of its transport activity and often results in clinically relevant drug-drug interactions. The purpose of this study was to investigate the effect of cetirizine, a second generation H1 antihistamine, on P-gp function and expression in vitro and in sit...

BACKGROUND Cetirizine is among the first second-generation H1 antihistamines (SGAHs) developed to provide selective H1 receptor inhibition without central nervous system depression. OBJECTIVE The aim of this review is to summarize the amount of data collected over 25 years of clinical use of cetirizine and compare this with data available for other SGAHs in the management of patients with all...

BACKGROUND Effects of the H1-antihistamine, cetirizine, were studied on daytime alertness and performance to establish whether the drug would be suitable for use by air personnel and others involved in skilled activity. METHODS The investigation was carried out in six healthy volunteers, and the effects of the drug (5, 10, and 15 mg) were studied on sleep latency, subjective sleepiness, digit...

We investigated the suitability of cetirizine HCl (cetirizine) for the initial treatment of chronic urticaria. A secondary aim was to identify the optimal alternative treatments when switching from this drug to other drugs in patients who are dissatisfied with cetirizine. We started cetirizine at a once-daily dose of 10 mg for 2 weeks and then, depending on the course of symptoms in individual ...

Although increased serum histamine levels and H1R expression in the plaque are seen in atherosclerosis, it is not known whether H1R activation is a causative factor in the development of the disease, or is a host defense response to atherogenic signals. In order to elucidate how pharmacological inhibition of histamine receptor 1 (H1R) signaling affects atherogenesis, we administered either ceti...

of the evidence on off-label doses of cetirizine for chronic urticaria ( hives) to. If higher than standard doses of antihistamines are to be considered, . Double-blind crossover study of high-dose cetirizine in cholinergic urticaria. Zuberbier T(1), Münzberger C, Haustein U, Trippas E, Burtin B, Mariz SD, Henz BM. Nov 10, 2011 . Urticaria (hives) is a common disorder that often presents with s...

OBJECTIVE To study the effect of nimesulide (4-nitro-2-phenoxymethane sulfonanilide) a non-steroidal anti-inflammatory drug, on antihistaminic activity of cetirizine. METHOD A randomized, double blind, cross over study was conducted in ten healthy male volunteers. Wheal and flare responses to histamine were measured by performing intradermal injection of histamine (2 micrograms base) diluted ...

Cetirizine is an antihistamine used in performance horses for the treatment of hypersensitivity reactions and as such a withdrawal time is necessary prior to competition. The objective of the current study was to describe the disposition and elimination of cetirizine following oral administration in order to provide additional serum concentration data upon which appropriate regulatory recommend...
