Animal experimental data
Cetirizine is a kind of antihistaminic, and main effect is selectivity retardance H
1-receptor.This anti-histamine activity of cetirizine is unequivocally established in all kinds of animal and human's body experiments.In the animal body and experiment in vitro show and take the activity that negligible anti-parasympathetic nervous effect and antiserum source property are arranged behind the cetirizine, xerostomia often appears after taking cetirizine.The body inner recipient shows that in conjunction with experiment cetirizine is only to H
1-receptor has affinity; Radiolabeled cetirizine in the autoradiography research mice body, result's demonstration enters the amount of the cetirizine of brain and can ignore.Rats in vitro experiment display system is taken cetirizine and can obviously do not occupied cerebellum H
1-receptor.
Pseudoephedrine hydrochloride is the sympatheticomimetic amine substance of a kind of Orally active, can alleviate abnormal rhinitis and cause nasal mucosa hyperemia, and performance alleviates the effect of nasal mucosa hyperemia, and the border effect of its generation is similar to ephedrine, and main effects is similar to amphetamine.
Cetirizine: in the research in 2 years of rat, when dosage at the dosage of every day regulation during to 20mg/kg (approximately the adult is with 15 times of mg/m2 calculating recommended dose every day), cetirizine does not have carcinogenecity.In the research in 2 years of mice, and when dosage during at 4mg/kg every day (approximately the adult calculates 2 times of recommended dose every day with mg/m2), the incidence rate that male mice is suffered from liver neoplasm does not increase, when dosage during at 16mg/kg every day (approximately the adult calculates 6 times of recommended dose every day with mg/m2), the incidence rate that male mice is suffered from optimum liver neoplasm increases.This slow releasing tablet is data clinically not also.
Pseudoephedrine: according to the prediction of national toxicity program, rat and mice 2 years studies show that, ephedrine sulfate (a kind of similar to pseudoephedrine aspect pharmacology, the medicine that structure is relevant with pseudoephedrine) is when dosage to 10 and 27mg/kg (about be grown up with mg/m of dosage in regulation every day
2Calculate recommended dose every day 1/3 and 1/2) time, do not have a carcinogenecity.
Cetirizine is not seen mutagenicity in (the inspection carcinogen) Ames test and mouse lymph lymphoma test, micronucleus test in test of human lymphoid's tumor and the rodent body is not had cavity.Equally, cetirizine and pseudoephedrine share with 1: 24 ratio, also do not have mutability and cavity in these trials.Yet, Ames test and the not strict test standard that depends on of mouse lymph lymphoma test.
In the research of rat genotoxicity, when cetirizine and pseudoephedrine Combined with Oral dosage reach 6/154mg/kg (approximately the adult is with 5 times of mg/m2 calculating recommended dose every day), reproductive performance there is not influence.
