Minor
Suspected
설명
Omeprazole does not have a pharmacokinetic interaction with pregabalin since pregabalin is not CYP-metabolised; however, both can cause peripheral oedema through independent mechanisms, producing additive fluid retention.
기전
Pregabalin causes peripheral oedema through an unclear mechanism, possibly related to calcium channel-mediated vascular tone changes; omeprazole rarely causes fluid retention; the combination is predominantly pharmacodynamic.
임상적 중요성
The interaction is minor and clinically relevant only in patients prone to fluid retention (e.g., cardiac failure, hypoalbuminaemia).
관리 방법
Monitor for peripheral oedema; no dose adjustment required; consider reviewing pregabalin dose if oedema worsens.
