This editorial by R Andrew McIvor contained an error relating to the dose of ipratropium (BMJ 2010;340:c833, doi:10.1136/bmj.c833). The first sentence of the third paragraph should have read: “Over the past two decades, the short acting anticholinergic, ipratropium, has been widely prescribed for maintenance treatment, at two inhalations of 20 μg (micrograms) [not 20 mg as stated] four times a day via a metered dose inhaler.”
