คำอธิบาย
Ranitidine may reduce the absorption rate of cephalexin by raising gastric pH, but overall bioavailability is not substantially altered, making this interaction clinically insignificant.
กลไก
Acid suppression by ranitidine can alter the dissolution rate of cephalexin capsules, potentially delaying Tmax; total absorption (AUC) is largely unaffected.
ความสำคัญทางคลินิก
No clinically meaningful reduction in cephalexin efficacy has been documented; the interaction is considered theoretical.
การจัดการ
No dose adjustment or timing modification is required.
