Vancomycin administration into the cerebrospinal fluid: a review

Area of Science:

• Pharmacology
• Infectious Diseases
• Neurosurgery

Background:

• Central nervous system (CNS) infections pose significant treatment challenges due to the blood-brain barrier.
• Vancomycin is a critical antibiotic for treating serious bacterial infections, including those affecting the CNS.

Purpose of the Study:

• To review the current evidence and principles for administering vancomycin directly into the cerebrospinal fluid (CSF) for treating CNS infections.
• To highlight the potential benefits and limitations of this therapeutic approach.

Main Methods:

• A literature search was conducted using MEDLINE and other sources for English-language articles.
• Case reports on CSF vancomycin administration were evaluated for dosing, outcomes, and toxicities.
• The review synthesized findings from anecdotal reports and basic principles of intrathecal drug administration.

Main Results:

• Direct CSF administration of vancomycin effectively bypasses the blood-brain barrier, achieving higher drug concentrations in the CNS.
• Current data on the safety, efficacy, and pharmacokinetics of CSF vancomycin is limited.
• Variability exists in recommended dosing regimens across reported cases.

Conclusions:

• Intracerebrospinal fluid (CSF) vancomycin administration may be essential for eradicating severe CNS infections.
• Conservative dosing is recommended due to potential toxicities associated with elevated CSF vancomycin levels.
• Further prospective studies are needed to establish optimal dosing and safety profiles.
