Loratadine is a commonly used anti-allergy drug, which belongs to the second generation of long-acting tricyclic antihistamines. It acts quickly, has strong effect, does not contain hormones, and is metabolized into more active desloratadine after absorption by the human body. It competitively inhibits histamine H1 receptor and inhibits allergic symptoms caused by histamine, without obvious anticholine and central inhibitory effects. It is used clinically to relieve symptoms associated with allergic rhinitis, such as sneezing, runny nose and itchy nose, as well as itching and burning of the eyes. It is also used to relieve the symptoms of chronic urticaria and other allergic skin diseases. Toxicology: No mutagenicity or malformation in animal tests.
