Summary
Moxifloxacin can disturb glucose control, and with glyburide there is an increased risk of severe hypoglycemia. Glyburide's long action and active metabolites make episodes more prolonged, especially in older or renally impaired patients.
What this interaction means in plain words
Glibenclamide and Moxifloxacin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Glibenclamide belongs to Endocrine; Moxifloxacin belongs to Anti Bacterial.
Why it happens
Fluoroquinolones enhance insulin release via beta-cell potassium channel effects, additive to glyburide.
What to do
Monitor blood glucose closely during therapy and educate the patient on hypoglycemia. Reduce the glyburide dose if needed or choose another antibiotic in high-risk patients.
