Minor
Suspected
Mô tả
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.
Cơ chế
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.
Ý nghĩa lâm sàng
The interaction is minor and clinically relevant only in patients prone to fluid retention (e.g., cardiac failure, hypoalbuminaemia).
Xử trí
Monitor for peripheral oedema; no dose adjustment required; consider reviewing pregabalin dose if oedema worsens.
