Cardiotoxicity of H1-antihistamines

H1 antihistamines and driving

Driving performances depend on cognitive, psychomotor and perception functions. The CNS adverse effects of some H1 antihistamines can alter the patient ability to drive. Data from studies using standardized objective cognitive and psychomotor tests (Choice Reaction Time, Critical Flicker Fusion. Digital Symbol Substitution Test), functional brain imaging (Positron Emission Tomography, functiona...

Interactions of the H1 antihistamines.

An interaction is taken to be the situation in which the administration of a drug or substance induces changes in the pharmacokinetics of another simultaneously administered drug – either increasing or decreasing the plasma concentration of the latter, and thus giving rise to the possibility of adverse reactions [1]. According to the primarily responsible pharmacological mechanism, H 1 antihist...

Comparative pharmacology of the H1 antihistamines.

H1 Antihistamines: Current Status and Future Directions

In this review, we compare and contrast the clinical pharmacology, efficacy, and safety of first-generation H1 antihistamines and second-generation H1 antihistamines. First-generation H1 antihistamines cross the blood-brain barrier, and in usual doses, they potentially cause sedation and impair cognitive function and psychomotor performance. These medications, some of which have been in use for...

Clinical pharmacokinetics of H1-receptor antagonists (the antihistamines).

This article reviews clinical pharmacokinetic data on the H1-receptor antagonists, commonly referred to as the antihistamines. Despite their widespread use over an extended period, relatively little pharmacokinetic data are available for many of these drugs. A number of H1-receptor antagonists have been assayed mainly using radioimmunoassay methods. These have also generally measured metabolite...
