Study Title:

MEDICATIONS WITH SIGNIFICANT ANTICHOLINERGIC PROPERTIES

Study Abstract

Table II lists common medications with significant anticholinergic properties and
potential adverse consequences, but is not all-inclusive. Any of the following signs and
symptoms may be caused by any of the medications in the lists below, alone or in
combination, as well as by other medications not listed here that have anticholinergic
properties.
This table is provided because: 1) Medications in many categories have anticholinergic
properties; 2) The use of multiple medications with such properties may be particularly
problematic because of the cumulative effects; and 3) Anticholinergic side effects are
particularly common and problematic, especially in the older individual61, 62.
