Telavancin is a semi-synthetic derivative of vanocymycin that has bactericidal activity against Methicillin-resistant Staphylococcus aureus (MRSA) and other gram-positive bacteria. MRSA is an important pathogen capable of causing hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), and skin and subcutaneous tissue infections among others.

For the treatment of complicated skin and skin structure infections (cSSSI) caused by gram-positive bacteria like methicillin-susceptible or -resistant Staphylococcus aureus, vancomycin-susceptible Enterococcus faecalis, and Streptococcus pyogenes, Streptococcus agalactiae, or Streptococcus anginosus group. Also for the treatment of adult patients with hospital-acquired bacterial pneumonia (HAP) and ventilator-associated bacterial pneumonia (VAP), known or suspected to be caused by susceptible isolates of Staphylococcus aureus (including methicillin-susceptible and methicillin-resistant S. aureus).

Telavancin is a semi-synthetic derivative of vancomycin, therefore the mode of bactericidal action is similar to vancomycin in which both antibiotics inhibit cell wall synthesis. Not only that, it displays concentration-dependent bactericidal action. Furthermore, telavancin is a more potent inhibitor (10-fold) of peptidoglycan synthesis and, unlike vancomycin, disrupts cell membrane integrity via its interaction with lipid II. AUC/MIC ratio best predicts the extent of in-vivo response in which the higher the ratio, the greater the bactericidal activity. The smallest ratio in which one would be able to observe no bacterial growth at 24 hours is 50. Maximal bactericidal activity is observed at a AUC/MIC ratio of 404.

Mechanism of action

Telavancin is a bactericidal lipoglycopeptide that is active against a broad range of gram-positive bacteria. Telavancin prevents polymerization of N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) and cross-linking of peptidoglycan by binding to D-Ala-D-Ala. As a result, inhibition of bacterial cell wall synthesis occurs. Furthermore, telavancin disrupts membrane potential and cell permeability as a result of the lipophillic side chain moiety. This additional bactericidal mechanism is what sets telavancin apart from vancomycin.


Telavancin demonstrates linear pharmacokinetics at doses between 1 and 12.5 mg/kg. Furthermore, 24 hours post-infusion of a dose of 7.5 to 15 mg/kg, activity against MRSA and penicillin-resistant Streptococcus pneumonia can still be observed. The trough concentration at this point of time is approximately 10 μg/mL. Telavancin also has poor bioavailability and must be administered over 30-120 minutes IV. Cmax, healthy subjects, 10 mg/kg = 93.6 ± 14.2 μg/mL; AUC (0- ∞), healthy subjects, 10 mg/kg = 747 ± 129 μg · h/mL; AUC (0-24h), healthy subjects, 10 mg/kg = 666± 107 μg · h/mL; Time to steady state = 3 days;

Volume of distribution

Vss, healthy subjects, 10 mg/kg = 0.14 L/kg

Protein binding

>90% to serum albumin in a concentration independent manner (despite being highly protein bound, antimicrobial activity of telavancin is not affected)


Metabolism of telavancin does not involve the cytochrome P450 enzyme system. Primary metabolite is called THRX-651540, but the metabolite pathway has not been identified.
