Pharmacokinetics, safety and tolerability of an oral suspension of fexofenadine for children with allergic rhinitis.

Allergic rhinitis (AR) is a common chronic condition in children and may impact a child's quality of life. Increasing treatment compliance may improve quality of life. An oral suspension of fexofenadine hydrochloride (HCl) has been developed to ease administration to children and may, therefore, improve treatment compliance.
