What is the UnifiedACB Tool?
A free, independent guide to published anticholinergic medication ratings and the questions they raise.
Make medication evidence easier to inspect
A medicine may be listed on one anticholinergic scale but missing or rated differently on another. UnifiedACB brings named ratings and source links together so a reader can see the disagreement, missing evidence, and what needs verification. The project grew from an effort to reconcile an ingredient directory and examine a separate experimental research model.
It is for clinicians, researchers, students, and people preparing for a conversation with a healthcare professional. The tool can help organize questions; it does not determine whether a particular medicine is appropriate for a person.
What you can find
Search 557 ingredient records, inspect named source categories such as Anticholinergic Cognitive Burden (ACB), Korean Anticholinergic Burden Scale (KABS), and CRIDECO Anticholinergic Load Scale (CALS), and review edition-limited 2023 AGS Beers Criteria ingredient flags for older-adult review. Names and categories are tied to their sources; they are not combined into a single published scale.
A separate model still under research
The experimental 0–10 model compares estimated free drug exposure at a stated regimen with a named laboratory affinity measure, then applies a bounded transformation. Twenty historical estimates illustrate the arithmetic. A general medication list has no validated UnifiedACB total or clinical risk bands. The site says “Score not assigned” when the evidence is insufficient.
Created by Maher Chaar, PharmD
UnifiedACB is Maher Chaar’s independent, personal project. He started it to make published anticholinergic medication ratings easier to compare, see where sources disagree, and identify evidence that still needs checking. He directs the project and maintains this website as a research and education resource.
This work is not an official project, clinical guideline, or endorsement from an employer, university, healthcare organization, or professional society. The website’s content has not been independently peer reviewed.
How it was made: Maher used AI extensively to help organize evidence, analyze data, write explanations, and develop the website. AI-assisted work can contain errors in medication matches, citations, values, calculations, or wording. Readers should check original sources and use clinical judgment.
