| Common Name | Cetirizine |

| Description | Cetirizine, also known as cetiderm or reactine, belongs to the class of organic compounds known as diphenylmethanes. Diphenylmethanes are compounds containing a diphenylmethane moiety, which consists of a methane wherein two hydrogen atoms are replaced by two phenyl groups. Cetirizine is a very strong basic compound (based on its pKa). In humans, cetirizine is involved in cetirizine h1-antihistamine action. Cetirizine is a potentially toxic compound. Cetirizine was first documented in 1987 (PMID: 2885355). Cetirizine crosses the blood–brain barrier only slightly, and for this reason, it produces minimal sedation compared to many other antihistamines (PMID: 15237765) (PMID: 10898119) (PMID: 15286093) (PMID: 1346737) (PMID: 2887304) (PMID: 10435475). |
