Acute coronary syndrome presenting after pseudoephedrine use and regression with beta-blocker therapy
Canadian Journal of Cardiology, 11/05/08

Akay S et al. - Pseudoephedrine, a common ingredient in cold relief drugs, dietary supplements and Chinese herbal tea, has potent sympathomimetic effects, impacting the cardiovascular system. The chemical properties and clinical effects of pseudoephedrine are similar to those of ephedrine, and its main effect is caused by the release of endogenous norepinephrine.

The present case highlights beta-blocker therapy as part of an initial intervention of pseudoephedrine-related cardiac symptoms.
