MAR 01, 2017 | AILEEN AHISKALI, PHARMD AND KRISTA GENS, PHARMD, BCPS-AQ-ID
A quick breakdown of the pros vs cons of the two polymyxins appears at the end of this article (see Table). 


 
Krista Gens, PharmD, BCPS-AQ ID is in infectious diseases clinical coordinator at Abbott Northwestern Hospital, Minneapolis, MN, where she helps maintain antimicrobial stewardship programs at Abbott Northwestern and at several Allina Health regional hospitals. She is an active member of ACCP, ASHP, and SIDP.
 
Aileen Ahiskali, PharmD, is an infectious diseases pharmacist and antimicrobial stewardship program coordinator at Hennepin County Medical Center in Minneapolis, MN, where she coordinates antimicrobial stewardship initiatives and rounds with the infectious diseases team daily.
