This course is designed to familiarize the student with some selected common disease conditions that he/she is expected to meet and deal with whether he/she works in a community pharmacy, a hospital, or other healthcare facilities. Both non-pharmacologic and pharmacologic approaches to the treatment of these particular clinical conditions will be discussed, based on drug and disease histories of the individual patient. The purpose of the course is to train the student to approach disease treatment in a rational way. The main goal is to provide treatment leading to cure from the particular health problem. If this is unattainable, the treatment effort should be directed toward improving the quality of life of the patient. The student is not required to reach a decision on diagnosis (this is not the job of a pharmacist), but should be familiar with the clinical signs and symptoms, laboratory, radiological and other tests necessary for diagnosis and/or follow-up prognosis of the disease condition. This will help in the selection of not only the pharmacologic drug group for proper treatment, but also of the best individual drug molecule in view of drug and disease history of the individual patient. The systematic scientific approach to the studied diseases will be taken as a model and a guide for approaching other clinical conditions that are beyond the scope of the course. The student should be familiar with the clinically relevant drug interactions including interactions with other drugs and foods, as well as environmental, industrial and agricultural chemicals as well as food additives.
