The use of topical


-blockers for the treatment of glaucoma is associated with an increased risk of airways obstruction in elderly patients, according to a report in the

British Medical Journal

. Researchers matched people who had used topical


-blockers with unexposed people by age and sex. An estimated 55 patients would

need to be treated to cause 1 case of airways obstruction each year.

Ophthalmologists, general practitioners, physicians, and pharmacists need to be aware of the possibility of airways obstruction in patients taking topical


-blockers for glaucoma, the researchers noted.


-blockers should be discontinued

immediately when a patient develops airways obstruction, and the ophthalmologist should be informed, the researchers added.

A repeat prescription that includes topical


-blockers and drugs for asthma should automatically sound an alarm, the authors concluded.
