We compared the effects of two histamine receptor blocking agents, chlorpheniramine (H1) and cimetidine (H2) on the airways of healthy and asthmatic subjects. Eleven healthy subjects and ten asthmatic patients underwent histamine aerosol challenge. A threshold dose (T) for response to histamine was determined for each subject using maximal expiratory flow rates on partial expiratory flow rates ...
The role of histamine in the regulation of food and water intake in mammals and birds of the review, this study evaluated the effects of intraperitoneal administration of chlorpheniramine as histamine H1-receptor antagonist, in broiler chicks on feed intake and satiety in water and was hungry. 32 male Ross broiler chicks reared in groups of four weeks, 16 samples (control and test) were then in...
Introduction: Propofol is an injectable anesthetics, which is used as sedation in surgery operations. The aim of the present study was to investigate the analgesic activity of chlorpheniramine, and its comparison with morphine and fentanyl ( opiod agents) in intraperitoneal propofol anesthesia in mice. Methods: 40 adult male mice were randomly assigned in 4 groups. Anesthesia was...
"Corrigendum to: High performance thin layer chromatography (HPTLC) method development and validation for the simultaneous determination of paracetamol, caffeine, chlorpheniramine phenylepherine in tablet formulation" published on 11 Aug 2022 by Akadémiai Kiadó.
A reliable method is presented for the chiral separation of three basic drugs (mexiletine, chlorpheniramine and propranolol) with serum albumins (human and porcine, HSA and PSA) as chiral selectors by capillary electrophoresis in combination with the partial filling technique. Based on the systematic optimization of operation variables, the chiral separation of mexiletine, chlorpheniramine and ...
Antihistaminic drugs are commonly used as symptomatic therapy of atopic dermatitis in dogs. Unfortunately, their clinical benefit is largely unsubstantiated. In a double-blinded, placebo-controlled, cross-over trial, the influence of dimetinden and of a combination of chlorpheniramine and hydroxyzine on pruritus and lesions was evaluated in 19 dogs. They were treated with either product or a pl...
The effects of three concentrations (2.5, 5 and 10 microg/ml) of aqueous-ethanolic extract of Z. multiflora bois, 10 nM chlorpheniramine, and saline on histamine (H1) receptors were tested on two groups of guinea pig tracheal chains [trachea incubated with indomethacin (Gr. 1), and indomethacin and propranolol (Gr. 2)]. The effective concentration of histamine causing 50% of maximum response (E...
The present pharmacological study was conducted to investigate a possible role of the brain histaminergic system in vocalization induced in guinea pig pups by maternal separation and isolation in an unfamiliar environment. The effects of drugs acting at histamine receptors were determined after intraperitoneal injection, comprising hydroxyzine and chlorpheniramine, both histamine H1 antagonists...
There exists a possibility of interactions of histaminergic system with other neurotransmitters and their receptors in the central nervous system. Experimental evidences suggest a possible inhibitory influence of histaminergic system on the dopaminergic system. To elucidate the possible interaction between the histaminergic and dopaminergic pathways, we devised a strategy to study their effects...
OBJECTIVES To compare the adverse effects of two regimens of chlorpheniramine plus chloroquine (CP+CQ) in children who live in a country where chloroquine resistant malaria is endemic. METHODS 99 children with acute uncomplicated malaria were randomised into two treatment groups. Group I received high dose chlorpheniramine (6 mg +12 mg/day for 7 days in children = 5 years; 8 mg + 18 mg/day fo...
