Combining Pharmacy and Genome-Wide Genotyping Data to Examine Medication Regimen Complexity Indices (MRCI), Drug-Drug and Gene-Drug Interactions in Transplant Patients
L. Callans, J. Obayemi, H. Gao, A. Shaked, B. Chang, B. Keating
Penn Transplant Institute, Hospital of the University of Pennsylvania, Philadelphia, USA, Philadelphia, PA
*Purpose: Polypharmacy, typically defined as the use of five or more medications, is a barrier to adherence, and the resulting complex medication regimens result in…
