Uses

To reduce the development of drug-resistant bacteria and maintain the effectiveness of moxifloxacin injection and other antibacterial drugs, moxifloxacin injection should be used only to treat or prevent 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.

Moxifloxacin injection is indicated for the treatment of adults (18 years of age or older) with infections caused by susceptible isolates of the designated microorganisms in the conditions listed below [see Dosage and Administration (2) and Use in Specific Populations (8.5)].


Culture and Susceptibility Testing

Appropriate culture and susceptibility tests should be performed before treatment in order to isolate and identify organisms causing infection and to determine their susceptibility to moxifloxacin [see Clinical Pharmacology (12.4)].  Therapy with moxifloxacin may be initiated before results of these tests are known; once results become available, appropriate therapy should be continued.

1.1 Acute Bacterial Sinusitis

Moxifloxacin is indicated for the treatment of Acute Bacterial Sinusitis caused by Streptococcus pneumoniae, Haemophilus influenzae, or Moraxella catarrhalis [see Clinical Studies (14.4)].

1.2 Acute Bacterial Exacerbation of Chronic Bronchitis

Moxifloxacin is indicated for the treatment of Acute Bacterial Exacerbation of Chronic Bronchitis caused by Streptococcus pneumoniae, Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, methicillin-susceptible Staphylococcus aureus, or Moraxella catarrhalis [see Clinical Studies (14.1)]

1.3 Community Acquired Pneumonia

Moxifloxacin is indicated for the treatment of Community Acquired Pneumonia caused by Streptococcus pneumoniae (including multi-drug resistant isolates*), Haemophilus influenzae, Moraxella catarrhalis, methicillin-susceptible Staphylococcus aureus, Klebsiella pneumoniae, Mycoplasma pneumoniae, or Chlamydophila pneumoniae

* MDRSP, Multi-drug resistant Streptococcus pneumoniae includes isolates previously known as PRSP (Penicillin-resistant S. pneumoniae), and are isolates resistant to two or more of the following antibiotics: penicillin (minimum inhibitory concentrations [MIC] ≥ 2 mcg/mL), 2nd generation cephalosporins (for example, cefuroxime), macrolides, tetracyclines, and trimethoprim/sulfamethoxazole [see Clinical Studies (14.2)].

1.4 Uncomplicated Skin and Skin Structure Infections

Moxifloxacin is indicated for the treatment of Uncomplicated Skin and Skin Structure Infections caused by methicillin-susceptible Staphylococcus aureus or Streptococcus pyogenes [see Clinical Studies (14.5)].

1.5 Complicated Skin and Skin Structure Infections

Moxifloxacin is indicated for the treatment of Complicated Skin and Skin Structure Infections caused by methicillin-susceptible Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, or Enterobacter cloacae [see Clinical Studies (14.6)].

1.6 Complicated Intra-Abdominal Infections

Moxifloxacin is indicated for the treatment of Complicated Intra-Abdominal Infections including polymicrobial infections such as abscess caused by Escherichia coli, Bacteroides fragilis, Streptococcus anginosus, Streptococcus constellatus, Enterococcus faecalis, Proteus mirabilis, Clostridium perfringens, Bacteroides thetaiotaomicron, or Peptostreptococcus species [see Clinical Studies (14.7)].

1.1 Acute Bacterial Sinusitis

Moxifloxacin is indicated for the treatment of Acute Bacterial Sinusitis caused by Streptococcus pneumoniae, Haemophilus influenzae, or Moraxella catarrhalis [see Clinical Studies (14.4)].

1.2 Acute Bacterial Exacerbation of Chronic Bronchitis

Moxifloxacin is indicated for the treatment of Acute Bacterial Exacerbation of Chronic Bronchitis caused by Streptococcus pneumoniae, Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, methicillin-susceptible Staphylococcus aureus, or Moraxella catarrhalis [see Clinical Studies (14.1)]

Other Information

Moxifloxacin is a synthetic broad spectrum antibacterial agent for intravenous administration.  Moxifloxacin, a fluoroquinolone, is available as a buffered salt of 1-cyclopropyl-7-[(S,S)-2,8-diazabicyclo[4.3.0]non-8-yl]-6-fluoro-8-methoxy-1,4-dihydro-4-oxo-3 quinoline carboxylic acid.  It is a slightly yellow to yellow crystalline substance.  Its chemical structure is as follows:

* 400 mg moxifloxacin equivalent to 437.5 mg of moxifloxacin hydrochloride.

**The pH may have been adjusted with sulfuric acid.  The pH is 5.0 to 6.0.


Each mL contains 1.6 mg of moxifloxacin. 

The appearance of the intravenous solution is clear.  The plastic container is fabricated from a specially designed multilayer plastic (freeflex®).  Solution is in contact with the polypropylene layer of this container and can leach out certain chemical components of the plastic in very small amounts within the expiration period.  The leachable compounds were all within acceptable limits based on animal toxicology studies.  

Moxifloxacin injection contains approximately 52.5 mEq (1,207 mg) of sodium in 250 mL.
