The Science behind the Tip

The Science behind the Tip The methodological quality of early studies of the association of systemic or topical ß-blocker therapy and depressed mood is weak. Most of the evidence supporting an association has used case reports. Further, the mechanism by which ß-blockers might induce depression remains unclear. Lipophilic ß- blockers easily penetrate the blood-brain barrier and should thus cause more central nervous system disturbances than hydrophilic ones. Yet, relative lipophilicity has not proved to play a role(1,2).

The increased use of ß-blockers in recent years in the treatment of myocardial infarction and heart failure has lead to renewed interest in the matter. Several syntheses of the data(3) and a meta-analysis of randomized clinical trials(2) have shown that the association is much weaker than originally believed and might even be non-existent. Additionally, a recent multicenter prospective study of postmyocardial infarction patients could not demonstrate an association in the first year of treatment(4).

In line with the cardiovascular literature, a retrospective observational population-based cohort study found no effect of topical ß-blockers on the prevalence of depression among glaucoma patients(5).
