The Systems Pharmacology Module occupies the third quarter of the year-long Introduction to Pharmacological Principles. The 9 week course is arranged into three modules: 5 sessions in the first module cover general pharmacological principles, 9 sessions in the second module focus on nervous and circulatory systems, and 10 sessions in the third and final module cover host defense and renal and endocrine systems. An understanding of systems pharmacology is necessary and valuable for all Pharmacology graduate students.
