Anticholinergic Risk Scale (ARS) The ARS tool is used to assess the risk of adverse effects due to anticholinergic drugs. Within the tool the medications are broken down into categories and each category is assigned points. To use ARS you must determine the point values of the anticholinergic drugs that the individual is taking, add up the points, and the higher the total points the greater the risk. The tool can be found in table 4 of the referenced article. This tool was developed by J.L. Rudolph, MD, M.J. Salow, PharmD, M.C. Angelini, MA, PharmD, and R.E. McGlinchey, PhD.
