Use
The first clinically interesting histamine H-receptor1 antagonists were introduced in the late 1940s and early 1950s. Several H-antihistaminics have a similar cardiac effect to that seen with astemizole1 and terfenadine. Serious cardiovascular adverse reactions have been reported when used concomitantly with imidazole antifungals and macrolide antibiotics. See also under astemizole.
