Use of angiotensin converting enzyme inhibitors in patients receiving therapeutic plasma exchange with a centrifuge-based apheresis system.

Angiotensin-converting enzyme inhibitors (ACEi) are frequently used antihypertensive medications with additional advantages such as reducing proteinuria and cardiovascular events. ACEi are commonly held at least 24 hours before a therapeutic plasma exchange (TPE) to reduce possibility of adverse events (AEs) including adverse drug reactions (ADR). The objective of this study was to determine if ACEi use increases the risk of ADR in patients receiving TPE with a conventional centrifuge-based apheresis system.
