Useful For

Vancomycin is a glycopeptide antibiotic, which is bactericidal against many gram-positive and some gram-negative cocci. It is useful in therapy of severe staphylococcal (including methicillin-resistant staphylococci) infections in patients who cannot receive or who have failed to respond to the penicillins and cephalosporins.


Strong correlations have been shown between serum levels of vancomycin and both therapeutic effect and toxicity in specific patient types.
