Severity: Contraindicated
Lisinopril and Protein a column: contraindicated interaction.
Last updated
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Patients taking ACE inhibitors who undergo immunoadsorption with a protein A column have had severe anaphylactoid reactions with flushing, hypotension, and dyspnea. Bradykinin accumulation is thought to be responsible.
What this interaction means in plain words
Lisinopril and Protein a column are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Why it happens
ACE inhibition reduces bradykinin breakdown, and column-activated bradykinin generation leads to anaphylactoid reactions.
What to do
Stop lisinopril well before the procedure (labeling suggests about 72 hours) and use an alternative antihypertensive. Consider a different apheresis membrane if the ACE inhibitor cannot be stopped.
