See Needy Meds for financial assistance information. Definition NCI Cetirizine is a metabolite of hydroxyzine and a selective peripheral histamine H1-receptor antagonist.
It is used for symptomatic treatment of seasonal and perennial allergic rhinitis and for chronic urticaria. NCI Definition MSH A potent second-generation histamine H1 antagonist that is effective in the treatment of allergic rhinitis, chronic urticaria, and pollen-induced asthma.
Unlike many traditional antihistamines, it does not cause drowsiness or anticholinergic side effects. Definition NCI A piperidine histamine H1-receptor antagonist with anti-allergic properties and without sedative effects. Loratadine blocks the H1 histamine receptor and prevents the Non sedating anti-h1 antihistamines during pregnancy that are caused by histamine activity on capillaries, bronchial smooth muscle, and gastrointestinal smooth muscle, including vasodilatation, increased capillary permeability, bronchoconstriction, and spasmodic contraction of gastrointestinal smooth muscle.
Loratadine does not cross the blood-brain barrier and does not cause central nervous system effects. Definition MSH A second-generation histamine H1 receptor antagonist used in the treatment of allergic rhinitis and urticaria.
It blocks a chemical released during an allergic response that causes itching, sneezing, runny nose, wheezing, and watery eyes. It is a type of antihistamine. Definition NCI A second generation, long-lasting selective histamine H1 receptor antagonist with antiinflammatory property. Fexofenadine is a highly selective and reversible competitor at peripheral H1 histamine receptors in the gastrointestinal GI tract, blood vessels, and bronchial smooth muscle.
In addition fexofenadine may also inhibit the late-phase allergic reaction by acting on Non sedating anti-h1 antihistamines during pregnancy or prostaglandins, or by producing an anti-platelet activating factor effect.
Overall, this agent blocks the actions of endogenous histamine, thereby leads to temporary relief of the negative symptoms associated with histamine and achieve effects such as decreased vascular permeability, reduction of pruritus and localized smooth muscle relaxation.
