Summary
Fluoroquinolone antimicrobials can alter blood sugar, potentially causing severe hypoglycemia in patients with diabetes, advanced age, or kidney issues. This interaction requires careful clinical consideration due to high risk.
Area of Science:
- Pharmacology
- Internal Medicine
- Infectious Diseases
Background:
- Fluoroquinolone antimicrobials are associated with dysglycemia.
- Hypoglycemia and hyperglycemia are potential side effects.
- The clinical significance of these effects, especially drug interactions, warrants investigation.
Purpose of the Study:
- To conduct a structured review of fluoroquinolone-induced hypoglycemia and hyperglycemia.
- To evaluate the clinical relevance of potential drug interactions with fluoroquinolones.
Main Methods:
- Systematic literature search in PubMed/Medline for English and Spanish articles.
- Inclusion of MESH terms: Hypoglycemia, Hyperglycemia, Quinolones, Ciprofloxacin, Levofloxacin, Moxifloxacin.
- Evaluation of interaction probability, severity, and clinical relevance in at-risk patients.
Main Results:
- 42 publications were identified, with 22 selected for detailed analysis.
- Patients on antidiabetic medications with risk factors (e.g., advanced age, renal failure) are at higher risk for severe hypoglycemia.
- The interaction between fluoroquinolones and antidiabetic agents is considered clinically relevant in these patients.
Conclusions:
- Fluoroquinolone use can lead to significant hypoglycemia, particularly in vulnerable patient populations.
- Clinicians must consider the high risk of severe hypoglycemia in patients with diabetes, advanced age, or renal impairment receiving fluoroquinolones.
- This drug interaction necessitates careful monitoring and management to prevent adverse events.
