Vancomycin Unit Converter
Vancomycin is a glycopeptide antibiotic primarily used to treat serious infections caused by gram-positive bacteria, particularly Methicillin-Resistant Staphylococcus aureus (MRSA).
Therapeutic Drug Monitoring (TDM) is essential to ensure efficacy while preventing nephrotoxicity (kidney damage) and ototoxicity. This converter facilitates switching between standard mass units (μg/mL, mg/L) and SI molar units (μmol/L).
Mass Units
StandardMicrograms per milliliter (Numerically equivalent to mg/L).
SI / Molar Units
Micromoles per liter (International Standard).
Clinical Context
Therapeutic Targets (Trough Levels):
• Standard: 10 – 15 μg/mL.
• Severe Infections (e.g., Meningitis, Pneumonia, Osteomyelitis): 15 – 20 μg/mL.
AUC/MIC: Current guidelines (ASHP/IDSA) prefer targeting an Area Under the Curve to Minimum Inhibitory Concentration (AUC/MIC) ratio of 400–600 for MRSA infections, rather than relying solely on trough levels.
Conversion Logic:
Molecular Weight of Vancomycin: ~1449.3 g/mol.
1 μg/mL ≈ 0.69 μmol/L.
1 μmol/L ≈ 1.45 μg/mL.
