On Drug Dosage Control Using Description Defeasible Logic

Drug-drug and drug-disease interactions are generally harmful. Some of these interactions could result from improper drug doses prescribed for a particular disease or from the unawareness the patient suffers from another disease. We aim in this paper to make a first step towards developing a knowledge based system that supports the decision making process undertaken by the physicians and pharmacists when prescribing drugs and the proper dosages. We need to formally represent knowledge about the drugs (e.g., family to which it belongs, proper doses), diseases and the conditions of the patient (e.g., patient with high cholesterol (LDL) and muscle pain disease). The drug which will employ in our case study is Lipitor. Lipitor is a cholesterol lowering drug from the statin family. The diseases which we will consider are liver and kidney diseases.
