Oritavancin is an glycopeptide antibiotic with bactericidal activity effective in treating infections caused by Gram-positive organisms. It treats complicated skin and skin structure infections. This drug demonstrates similar activity to vancomycin, but it has stronger activity against Staphylococcus and Enterococcus. The pharmacokinetics and pharmacodynamics of oritavancin appear to be favourable and once-daily dosing is likely. The incidence of multi-drug resistant bacteria is increasing and explorations into additional treatment options are essential. Oritavancin is marketed under the brand name Orbactiv. Orbactiv is indicated for the treatment of adult patients with acute bacterial skin and skin structure infections caused or suspected to be caused by susceptible isolates of designated Gram-positive microorganisms. Oritavancin has the following mechanism of action: 1) Inhibition of the transglycosylation (polymerisation) step of cell wall biosynthesis by binding to the stem peptide of peptidoglycan precursors 2) Inhibition of the transpeptidation (crosslinking) step of cell wall biosynthesis by binding to the peptide bridging segments of the cell wall 3) Disruption of bacterial membrane integrity, leading to depolarisation, increased permeability and rapid cell death.

Acute bacterial skin and skin structure infection 16 Sources: http://www.orbactiv.com/pdfs/orbactiv-prescribing-information.pdf	Curative		Approved 8429	ORBACTIV Approved Use ORBACTIV is a lipoglycopeptide antibacterial drug indicated for the treatment of adult patients with acute bacterial skin and skin structure infections caused or suspected to be caused by susceptible isolates of designated Gram-positive microorganisms. (1.1) To reduce the development of drug-resistant bacteria and maintain the effectiveness of ORBACTIV and other antibacterial drugs, ORBACTIV should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. (1.2) 1.1 Acute Bacterial Skin and Skin Structure Infections ORBACTIV® (oritavancin) for injection is indicated for the treatment of adult patients with acute bacterial skin and skin structure infections (ABSSSI) caused by susceptible isolates of the following Gram-positive microorganisms: Staphylococcus aureus (including methicillin-susceptible and methicillin–resistant isolates), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus anginosus group (includes S. anginosus, S. intermedius, and S. constellatus), and Enterococcus faecalis (vancomycin-susceptible isolates only). 1.2 Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of ORBACTIV and other antibacterial drugs, ORBACTIV should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Launch Date 2014

There was an increase of 15% in this metabolic ratio. The Day 1/Day-4 geometric mean ratio (point estimate) and 90% CI was 1.155 (0.957, 1.395), suggesting that oritavancin may be a weak inhibitor of CYP2C19.

The Day 1/Day -4 geometric mean ratio (point estimate) and 90% CI (N=13 subjects) was 0.692 (0.431, 1.110). These findings indicate a 31% decrease in the urinary dextromethorphan/dextrorphan ratio, and that oritavancin is a weak inducer of CYP2D6.

The Day 1/Day -4 geometric mean ratio (point estimate) and 90% CI for CL/F was 1.239 (1.135, 1.353). The 24% increase in the midazolam CL/F and decrease (18%) in the midazolam AUC0-inf indicates that oritavancin is a weak inducer of CYP3A4.
