Clinical application of H_1 antihistamines in children with allergic rhinitis / 中国实用儿科杂志

ABSTRACT

The incidence of allergic rhinitis in children increases year by year,and H_1 antihistamines play a role in the control of allergic diseases by blocking the binding of histamine and H_1 receptor. The second-generation H_1 antihistamines have more stable binding,better specificity,lower central inhibitory effect and longer action time,and can effectively improve the symptoms of the nose and eyes,which is the firstline drug for the treatment of allergic rhinitis in children. At present,there aren't objective testing methods to evaluate the effectiveness and safety of antihistamines. Therefore,the dosage for children should be adjusted according to body weight,appropriate dosage forms should be selected,age limit should be paid attention to,dosage varieties should be individualized as far as possible,and reasonable course of treatment should be applied.
