12.1 Mechanism of Action Moxifloxacin hydrochloride is a member of the fluoroquinolone class of antibacterial agents [see Microbiology (12.4) ] .

Moxifloxacin tablets are a fluoroquinolone antibacterial indicated for treating infections in adults 18 years of age and older caused by designated susceptible bacteria, in the conditions listed below: Community Acquired Pneumonia ( 1.1 ) Skin and Skin Structure Infections: Uncomplicated ( 1.2 ) and Complicated ( 1.3 ) Complicated Intra-Abdominal Infections ( 1.4 ) Plague ( 1.5 ) Acute Bacterial Sinusitis ( 1.6 ) Acute Bacterial Exacerbation of Chronic Bronchitis ( 1.7 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of moxifloxacin tablets and other antibacterial drugs. Moxifloxacin tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. ( 1.8 ) 1.1 Community Acquired Pneumonia Moxifloxacin tablets are indicated in adult patients for the treatment of Community Acquired Pneumonia caused by susceptible isolates of Streptococcus pneumoniae (including multi-drug resistant Streptococcus pneumoniae [MDRSP]) , Haemophilus influenzae, Moraxella catarrhalis, methicillin-susceptible Staphylococcus aureus, Klebsiella pneumoniae, Mycoplasma pneumoniae, or Chlamydophila pneumoniae [see Clinical Studies (14.3) ] . MDRSP isolates are isolates resistant to two or more of the following antibacterial drugs: penicillin (minimum inhibitory concentrations [MIC] ≥ 2 mcg/mL), 2nd generation cephalosporins (for example, cefuroxime), macrolides, tetracyclines, and trimethoprim/sulfamethoxazole. 1.2 Uncomplicated Skin and Skin Structure Infections Moxifloxacin tablets are indicated in adult patients for the treatment of Uncomplicated Skin and Skin Structure Infections caused by susceptible isolates of methicillin-susceptible Staphylococcus aureus or Streptococcus pyogenes [see Clinical Studies (14.4) ]. 1.3 Complicated Skin and Skin Structure Infections Moxifloxacin tablets are indicated in adult patients for the treatment of Complicated Skin and Skin Structure Infections caused by susceptible isolates of methicillin-susceptible Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, or Enterobacter cloacae [see Clinical Studies (14.5) ]. 1....

( 8.6 , 8.7 ) 2.1 Dosage in Adult Patients The dose of moxifloxacin is 400 mg (orally) once every 24 hours. The duration of therapy depends on the type of infection as described in Table 1. Table 1: Dosage and Duration of Therapy in Adult Patients a) Due to the designated pathogens [see (1) ] . b) Sequential therapy (intravenous to oral) may be instituted at the discretion of the physician c) Drug administration should begin as soon as possible after suspected or confirmed exposure to Yersinia pestis . Type of Infection a Dose Every 24 hours Duration b (days) Community Acquired Pneumonia ( 1.1 ) 400 mg 7 to 14 Uncomplicated Skin and Skin Structure Infections (SSSI) ( 1.2 ) 400 mg 7 Complicated SSSI ( 1.3 ) 400 mg 7 to 21 Complicated Intra-Abdominal Infections ( 1.4 ) 400 mg 5 to 14 Plague ( 1.5 ) C 400 mg 10 to 14 Acute Bacterial Sinusitis (ABS) ( 1.6 ) 400 mg 10 Acute Bacterial Exacerbation of Chronic Bronchitis (ABECB) ( 1.7 ) 400 mg 5 Conversion of Intravenous to Oral Dosing in Adults Intravenous formulation is indicated when it offers a route of administration advantageous to the patient (for example, patient cannot tolerate an oral dosage form). When switching from intravenous to oral formulation, no dosage adjustment is necessary. Patients whose therapy is started with moxifloxacin hydrochloride injection may be switched to moxifloxacin tablets when clinically indicated at the discretion of the physician. 2.2 Important Administration Instructions With Multivalent Cations Administer moxifloxacin tablets at least 4 hours before or 8 hours after products containing magnesium, aluminum, iron or zinc, including antacids, sucralfate, multivitamins and didanosine buffered tablets for oral suspension or the pediatric powder for oral solution [see (7.1) and Clinical Pharmacology (12.3) ].

The data described below reflect exposure to moxifloxacin hydrochloride in 14981 patients in 71 active controlled Phase II to IV clinical trials in different indications [see (1) ] . The population studied had a mean age of 50 years (approximately 73% of the population was less than 65 years of age), 50% were male, 63% were Caucasian, 12% were Asian and 9% were Black. Patients received moxifloxacin 400 mg once daily oral, intravenous, or sequentially (intravenous followed by oral). Treatment duration was usually 6 to 10 days, and the mean number of days on therapy was 9 days. Discontinuation of moxifloxacin due to occurred in 5% of patients overall, 4% of patients treated with 400 mg PO, 4% with 400 mg intravenous and 8% with sequential therapy 400 mg oral/intravenous. The most common (>0.3%) leading to discontinuation with the 400 mg oral doses were nausea, diarrhea, dizziness, and vomiting. The most common adverse reaction leading to discontinuation with the 400 mg intravenous dose was rash. The most common leading to discontinuation with the 400 mg intravenous/oral sequential dose were diarrhea, pyrexia....
