Effects of two antihistamine drugs on actual driving performance.

A double blind placebo controlled experiment was conducted measuring the effects of the centrally active antihistamine triprolidine and the peripherally acting antihistamine terfenadine on actual driving performance in a group of experienced women drivers.

Antihistamine use in children.

This review provides an overview of the use of antihistamines in children. We discuss types of histamine receptors and their mechanism of action, absorption, onset and duration of action of first-generation and second-generation H(1)-antihistamines, as well as elimination of H(1)-antihistamines which has important implications for dosing in children. The rationale for the use of H(1)-antihistam...
