Lena Olsén 2007. Drugs in horses: pharmacokinetics and pharmacodynamics Doctoral thesis ISSN 1652-6880, ISBN978-91-576-7336-7 In this thesis the fate and effect of some drugs have been examined in horses. Studies have also been performed to explore some factors which may affect the pharmacokinetics and the pharmacodynamics of drugs in horses. Investigations on the drug metabolising enzyme cytoc...
A common approach in resolving enantiomers of chiral basic drugs by capillary electrophoresis (CE) is to use cyclodextrins (especially their anionic derivatives) as chiral selector in the acidic buffer (pH ≤ 3) in normal or reversed (carrier) mode. Then, some organic modifiers are added to the buffer solution if the resolution is not satisfactory. In case of cetirizine (CTN), applying the same ...
The conditions for identification were determined for four histamine antagonists: clemastine fumarate, loratadine, cetirizine dihydrochloride and desloratadine by TLC (thin-layer chromatography) method. The selected chromatographic conditions were used to develop a densitometric method for the content determination of the histamine antagonists in medicinal products and substances. The statistic...
Levocetirizine is the pharmacologically active enantiomer of cetirizine. It is a potent histamine H-1 receptor antagonist with anti-inflammatory and antiallergic properties. The review analyses the levocetirizine's properties in terms of safety and efficacy both in allergic rhinitis and urticarioid syndromes.
The present study evaluates the impact of P-glycoprotein (P-gp) on plasma-brain disposition and transepithelial transport of sedating versus nonsedating H1-antagonists using multidrug-resistant (mdr) gene 1a and 1b (mdr1a/b) knockout (KO) mice and human MDR1-transfected Madin-Darby canine kidney (MDCK) cells. Three nonsedating (cetirizine, loratadine, and desloratadine) and three sedating (diph...
We examined the effects of two over-the-counter H1-antihistamines on the progression of fatty liver disease in male C57Bl/6 wild-type and apolipoprotein E (ApoE)-/- mice. Mice were fed a high-fat diet (HFD) for 3 mo, together with administration of either cetirizine (4 mg/kg body wt) or fexofenadine (40 mg/kg body wt) in drinking water. Antihistamine treatments increased body weight gain, gonad...
The histamine H4 receptor (H4R) is a promising target for the treatment of pruritus. A clinical study was conducted to evaluate the safety and efficacy of the H4R antagonist, JNJ 39758979 [(R)-4-(3-amino-pyrrolidin-1-yl)-6-isopropyl-pyrimidin-2-ylamine], on histamine-induced pruritus in healthy subjects. A single oral dose of 600 mg JNJ 39758979, 10 mg cetirizine, or placebo was administered in...
