Desloratadine Ameliorates Olfactory Disorder and Suppresses AMPA Receptor GluA1 Expression in Allergic Rhinitis Rat
AbstractAllergic rhinitis (AR) is an IgE-mediated inflammation which causes olfactory dysfunction. Antihistamines have been widely used to treat AR while few studies have investigated the effect of antihistamines on improving the sense of smell. In addition, the underlying mechanisms are not well elucidated. We established the ovalbumin (OVA)-induced allergic rhinitis rat model and administrated desloratadine to AR rats. The AR symptoms, serum level of OVA-specific IgE and IL-17, and expression of IL-4, IL-5 and IL-13 in nasal mucosa were measured. The olfactory dysfunction was monitored by buried food test and the express...

Carboxymethyl-botryosphaeran stabilized carbon nanotubes aqueous dispersion: A new platform design for electrochemical sensing of desloratadine.
Abstract The polysaccharide carboxymethyl-botryosphaeran (CMB) was used to improve the dispersion of multi-walled carbon nanotubes (MWCNTs) in water. This feature was applied in modifying a glassy carbon electrode (GCE) to construct a sensitive voltammetric sensor for the determination of desloratadine (DESL), a tricyclic antihistamine. The morphology and spectroscopic behavior of the sensor were evaluated. The modified sensor was characterized as homogeneous, and presented a higher electroactive area and a lower charge transfer resistance compared to the unmodified GCE. Using linear sweep voltammetry at 25 m...

Biopharmaceutical classification of desloratadine - not all drugs are classified the easy way.
Abstract The biopharmaceutical classification of drugs was designed as a basis for bio-waivers - a mechanism with the double ethical benefit of delivering new drug formulations to the market with less human testing and lower cost. However, many drugs defy simple classification because in vitro permeability and stability assessment can be challenging as shown in this study for desloratadine. Literature shows that desloratadine is highly soluble, while data on luminal stability and permeability are circumstantial. Combined with borderline bioavailability and not really known fraction of absorbed dose, desloratadine ...

Metabolism of desloratadine by chimeric TK-NOG mice transplanted with human hepatocytes.
Abstract 1. Desloratadine is an antiallergic drug with species-dependent metabolic profiles in mice, rats, monkeys, and humans. We investigated whether humanized-liver mice could reproduce the reported human-specific in vivo metabolic profile for desloratadine in terms of the formation of 3-hydroxydesloratadine and its O-glucuronide.2. Hepatocytes prepared from humans and humanized-liver mice both preferentially catalyzed the formation of 3-hydroxydesloratadine and its O-glucuronide in vitro.3. After a single oral administration of desloratadine, plasma levels of desloratadine and its metabolites (3-hydroxydeslora...

To switch or not to switch —first Germany-wide study from the perspective of pharmacists in the European environment
ConclusionPharmacists strongly welcome further switches. This leads to high acceptance rates, especially for a switch of desloratadine, as this was the most named active ingredient possible for a switch within the survey.Impact of findings on practice statementsThe outcome of this survey can support pharmaceutical companies in decision-making about which active substances they should submit a switch application for. Additionally, this helps fulfil patient needs, because pharmacists know best what is beneficial for patient self-care. In addition, all other actors involved in this process can see what is required and can ret...

Histamine and Delirium: Current Opinion
This study indicated that switch from H2 blockers to PPIs reduced delirium and, thus, providing an appropriate strategy to combat drug-induced delirium using antiulcer drugs (Fujii et al., 2012). The ventrolateral preoptic nucleus is a sleep-promoting nucleus located in the basal forebrain. A commonly used intravenous anesthetic, propofol, had been reported to induce sleep and augment the firing rate of neurons in ventrolateral GABAergic preoptic nucleus, but the underlining mechanism is yet to be clearly determined. Interestingly, the propofol-induced inhibition of inhibitory postsynaptic currents on noradrenalin-inhibite...

Ecotoxic effects of loratadine and its metabolic and light-induced derivatives.
Abstract Loratadine and desloratadine are second-generation antihistaminic drugs. Because of human administration, they are continuously released via excreta into wastewater treatment plants and occur in surface waters as residues and transformation products (TPs). Loratadine and desloratadine residues have been found at very low concentrations (ng/L) in the aquatic environment but their toxic effects are still not well known. Both drugs are light-sensitive even under environmentally simulated conditions and some of the photoproducts have been isolated and characterized. The aim of the present study was to investi...

Screening and evaluation of fungal resources for loratadine metabolites.
Abstract Loratadine is a selective inverse agonist of peripheral histamine H1-receptors. Microbial biotransformation gained a lot of attention for its ability to convert molecules to valuable medicinally active substances. The main objective of the present research was to investigate the ability of different fungi to biotransform the drug loratadine to its active metabolite desloratadine, because desloratadine is four times more potent, possess longer duration of action than loratadine and is effective at low doses. The screening studies were performed with selected fungi using their respective broth media and ste...

Improving mechanical properties of desloratadine via multicomponent crystal formation.
We report the first multicomponent crystal of desloratadine, an important anti-histamine drug, with a pharmaceutically acceptable coformer of benzoic acid. The single crystal structure analysis revealed that this novel multicomponent crystal is categorized as salt due to the proton transfer from benzoic acid to the desloratadine molecule. By forming the salt multicomponent crystal, we demonstrated that the tabletability and plasticity of the multicomponent crystal was improved from the parent drug. In addition, neither capping nor lamination tendency was observed in the desloratadine-benzoic acid multicomponent crystal. Th...

Association of ORAI1 gene polymorphisms with chronic spontaneous urticaria and the efficacy of the nonsedating H1 antihistamine desloratadine
Chronic spontaneous urticaria (CSU) is a common skin disease associated with mast cell activation and degranulation.1,2 The degranulation process of mast cells is mediated mainly by calcium-release –activated calcium channels–mediated Ca2+ influx. ORAI1, encoded by ORAI1 gene, is the pore-forming subunit of calcium-release–activated calcium channels.3-5 A study on ORAI1 knockout mouse demonstrated that ORAI1 is essential for mast cell degranulation, leukotriene (LTC4) secretion, histami ne release as well as TNF-α secretion.
