What is Loratidine?
Loratadine (INN) is a second-generation used to treat allergies. In structure, it is closely related to tricyclic antidepressants, such as imipramine, and is distantly related to the atypical antipsychotic quetiapine.
It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system. Loratadine is marketed by Schering-Plough under several trade names (e.g., Claritin) and also by Shionogi in Japan. It is available as a generic drug and is marketed for its nonsedating properties. There is a version named combined with pseudoephedrine, a decongestant; known as pseudoephedrine/loratadine.
