Pharmacy Resources and Selected Medical Terminology Dr. Lee PHAR 672 Fall 2024 1 Lecture Objectives 1. State the important features of a reliable source of medical or drug information; 2. Give examples of reliable source of medical or drug information. 3. Given a drug information question, determine what selected source of drug information should be selected. 2 Where do PHARMACISTS go to find information about drug? If someone asks a pharmacist a question related to drugs, where should the pharmacist go to look up information? 3 Drug Information Resources: NEED to be reliable, reproducible, and transparent 4  Package Insert (Prescribing Information) https://dailymed.nlm.nih.gov/dailymed/ DailyMed (from the NIH) gives us a chance to find the prescribing information (“package insert’) The package insert (prescribing information) and the medication guide (for patients) come with the medications to the pharmacy. Some are also available at the drug’s website (if a website is available). 5  Package Insert (Prescribing Information) https://dailymed.nlm.nih.gov/dailymed/ DailyMed (from the NIH) gives us a chance to find the prescribing information (“package insert’) The package insert (prescribing information) and the medication guide (for patients) come with the medications to the pharmacy.
