Description
11 DESCRIPTION Levofloxacin is a synthetic broad-spectrum antibacterial agent for oral administration. Chemically, levofloxacin, a chiral fluorinated carboxyquinolone, is the pure (-)-(S)-enantiomer of the racemic drug substance ofloxacin. The chemical name is (-)-(S)-9-fluoro-2,3-dihydro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-7H-pyrido[1,2,3-de]-1,4-benzoxazine-6-carboxylic acid hemihydrate. Figure 1: The Chemical Structure of Levofloxacin [Chemical Structure] The molecular formula is C18H20FN3O4 • ½ H2O and the molecular weight is 370.38. Levofloxacin USP is a pale or bright yellow, crystalline powder. The molecule exists as a zwitterion at the pH conditions in the small intestine. The data demonstrate that from pH 0.6 to 5.8, the solubility of levofloxacin USP is essentially constant (approximately 100 mg/mL). Levofloxacin USP is considered soluble to freely soluble in this pH range, as defined by USP nomenclature. Above pH 5.8, the solubility increases rapidly to its maximum at pH 6.7 (272 mg/mL) and is considered freely soluble in this range. Above pH 6.7, the solubility decreases and reaches a minimum value (about 50 mg/mL) at a pH of approximately 6.9. Levofloxacin USP has the potential to form stable coordination compounds with many metal ions. This in vitro chelation potential has the following formation order: Al+3>Cu+2>Zn+2>Mg+2>Ca+2. Excipients and Description of Dosage Forms Levofloxacin tablets are available as film-coated tablets and contain the following inactive ingredients: 250 mg, 500 mg and 750 mg (as expressed in the anhydrous form): croscarmellose sodium, hypromellose, magnesium stearate, microcrystalline cellulose, polyethylene glycol 400, polysorbate 80, and titanium dioxide. In addition 250 mg contains iron oxide red and 500 mg contains iron oxide red and iron oxide yellow.

Indications & Usage
1 INDICATIONS AND USAGE Levofloxacin tablets are indicated for the treatment of adults (≥18 years of age) with mild, moderate, and severe infections caused by susceptible isolates of the designated microorganisms in the conditions listed in this section. Levofloxacin injection is indicated when intravenous administration offers a route of administration advantageous to the patient (e.g., patient cannot tolerate an oral dosage form). 1.1 Nosocomial Pneumonia Levofloxacin tablets are indicated for the treatment of nosocomial pneumonia due to methicillin-susceptible Staphylococcus aureus, Pseudomonas aeruginosa, Serratia marcescens, Escherichia coli, Klebsiella pneumoniae, Haemophilus influenzae, or Streptococcus pneumoniae. Adjunctive therapy should be used as clinically indicated. Where Pseudomonas aeruginosa is a documented or presumptive pathogen, combination therapy with an anti-pseudomonal β-lactam is recommended [see CLINICAL STUDIES (14.1)]. 1.2 Community-Acquired Pneumonia: 7 to 14 day Treatment Regimen Levofloxacin tablets are indicated for the treatment of community-acquired pneumonia due to methicillin-susceptible Staphylococcus aureus, Streptococcus pneumoniae (including multi-drug-resistant Streptococcus pneumoniae [MDRSP]), Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis, Chlamydophila pneumoniae, Legionella pneumophila, orMycoplasma pneumoniae [see DOSAGE AND ADMINISTRATION (2.1) and CLINICAL STUDIES (14.2)]. MDRSP isolates are isolates resistant to two or more of the following antibacterials: penicillin (MIC ≥2 mcg/mL), 2nd generation cephalosporins, e.g., cefuroxime, macrolides, tetracyclines and trimethoprim/sulfamethoxazole. 1.3 Community-Acquired Pneumonia: 5-day Treatment Regimen Levofloxacin tablets are indicated for the treatment of community-acquired pneumonia due to Streptococcus pneumoniae (excluding multi-drug-resistant isolates [MDRSP]), Haemophilus influenzae, Haemophilus parainfluenzae, Mycoplasma pneumoniae, or Chlamydophila pneumoniae [see DOSAGE AND ADMINISTRATION (2.1) and CLINICAL STUDIES (14.3)]. 1.4 Complicated Skin and Skin Structure Infections Levofloxacin tablets are indicated for the treatment of complicated skin and skin structure infections due to methicillin-susceptible Staphylococcus aureus, Enterococcus faecalis, Streptococcus pyogenes,or Proteus mirabilis [see CLINICAL STUDIES (14.5)]. 1.5 Uncomplicated Skin and Skin Structure Infections Levofloxacin tablets are indicated for the treatment of uncomplicated skin and skin structure infections (mild to moderate) including abscesses, cellulitis, furuncles, impetigo, pyoderma, wound infections, due to methicillin-susceptible Staphylococcus aureus, or Streptococcus pyogenes. 1.6 Chronic Bacterial Prostatitis Levofloxacin tablets are indicated for the treatment of chronic bacterial prostatitis due to Escherichia coli, Enterococcus faecalis, or methicillin-susceptible Staphylococcus epidermidis [see CLINICAL STUDIES (14.6)]. 1.7 Inhalational Anthrax (Post-Exposure) Levofloxacin tablets are indicated for inhalational anthrax (post-exposure) to reduce the incidence or progression of disease following exposure to aerosolized Bacillus anthracis. The effectiveness of levofloxacin tablets is based on plasma concentrations achieved in humans, a surrogate endpoint reasonably likely to predict clinical benefit. Levofloxacin tablets have not been tested in humans for the post-exposure prevention of inhalation anthrax. The safety of levofloxacin tablets in adults for durations of therapy beyond 28 days or in pediatric patients for durations of therapy beyond 14 days has not been studied. Prolonged levofloxacin tablets therapy should only be used when the benefit outweighs the risk [see DOSAGE AND ADMINISTRATION (2.1, 2.2) and CLINICAL STUDIES (14.9)]. 1.8 Plague Levofloxacin tablets are indicated for treatment of plague, including pneumonic and septicemic plague, due to Yersinia pestis (Y. pestis) and prophylaxis for plague in adults and pediatric patients, 6 months of age and older. Efficacy studies of levofloxacin tablets could not be conducted in humans with plague for ethical and feasibility reasons. Therefore, approval of this indication was based on an efficacy study conducted in animals [see DOSAGE AND ADMINISTRATION (2.1, 2.2) and CLINICAL STUDIES (14.10)]. 1.9 Complicated Urinary Tract Infections: 5-day Treatment Regimen Levofloxacin tablets are indicated for the treatment of complicated urinary tract infections due to Escherichia coli, Klebsiella pneumoniae, or Proteus mirabilis [see CLINICAL STUDIES (14.7)]. 1.10 Complicated Urinary Tract Infections: 10-day Treatment Regimen Levofloxacin tablets are indicated for the treatment of complicated urinary tract infections (mild to moderate) due to Enterococcus faecalis, Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, or Pseudomonas aeruginosa [see CLINICAL STUDIES (14.8)]. 1.11 Acute Pyelonephritis: 5 or 10-day Treatment Regimen Levofloxacin tablets are indicated for the treatment of acute pyelonephritis caused by Escherichia coli, including cases with concurrent bacteremia [see CLINICAL STUDIES (14.7, 14.8)]. 1.12 Uncomplicated Urinary Tract Infections Levofloxacin tablets are indicated for the treatment of uncomplicated urinary tract infections (mild to moderate) due to Escherichia coli, Klebsiella pneumoniae, or Staphylococcus saprophyticus. Because fluoroquinolones, including levofloxacin tablets, have been associated with serious adverse reactions [see WARNINGS AND PRECAUTIONS (5.1 TO 5.15)] and for some patients uncomplicated urinary tract infection is self-limiting, reserve levofloxacin tablets for treatment of uncomplicated urinary tract infections in patients who have no alternative treatment options. 1.13 Acute Bacterial Exacerbation of Chronic Bronchitis Levofloxacin tablets are indicated for the treatment of acute bacterial exacerbation of chronic bronchitis (ABECB) due to methicillin-susceptible Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, Haemophilus parainfluenzae, or Moraxella catarrhalis. Because fluoroquinolones, including levofloxacin tablets, have been associated with serious adverse reactions [see WARNINGS AND PRECAUTIONS (5.1 TO 5.15)] and for some patients ABECB is self-limiting, reserve levofloxacin tablets for treatment of ABECB in patients who have no alternative treatment options. 1.14 Acute Bacterial Sinusitis: 5-day and 10 to 14 day Treatment Regimens Levofloxacin tablets are indicated for the treatment of acute bacterial sinusitis (ABS) due to Streptococcus pneumoniae, Haemophilus influenzae, or Moraxella catarrhalis [see CLINICAL STUDIES (14.4)]. Because fluoroquinolones, including levofloxacin tablets, have been associated with serious adverse reactions [see WARNINGS AND PRECAUTIONS (5.1 TO 5.15)] and for some patients ABS is self-limiting, reserve levofloxacin tablets for treatment of ABS in patients who have no alternative treatment options. 1.15 Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of levofloxacin tablets and other antibacterial drugs, levofloxacin tablets 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. Culture and susceptibility testing Appropriate culture and susceptibility tests should be performed before treatment in order to isolate and identify organisms causing the infection and to determine their susceptibility to levofloxacin [see MICROBIOLOGY (12.4)]. Therapy with levofloxacin tablets may be initiated before results of these tests are known; once results become available, appropriate therapy should be selected. As with other drugs in this class, some isolates of Pseudomonas aeruginosa may develop resistance fairly rapidly during treatment with levofloxacin tablets. Culture and susceptibility testing performed periodically during therapy will provide information about the continued susceptibility of the pathogens to the antimicrobial agent and also the possible emergence of bacterial resistance.
Dosage and Administration
2 DOSAGE AND ADMINISTRATION 2.1 Dosage in Adult Patients with Normal Renal Function The usual dose of levofloxacin tablets is 250 mg, 500 mg, or 750 mg administered orally every 24 hours, as indicated by infection and described in Table 1. These recommendations apply to patients with creatinine clearance ≥ 50 mL/min. For patients with creatinine clearance <50 mL/min, adjustments to the dosing regimen are required [see DOSAGE AND ADMINISTRATION (2.3)].

Þ Drug administration should begin as soon as possible after suspected or confirmed exposure to aerosolized B. anthracis. This indication is based on a surrogate endpoint. Levofloxacin plasma concentrations achieved in humans are reasonably likely to predict clinical benefit [see CLINICAL STUDIES (14.9)]. ß The safety of levofloxacin tablets in adults for durations of therapy beyond 28 days or in pediatric patients for durations beyond 14 days has not been studied. An increased incidence of musculoskeletal adverse events compared to controls has been observed in pediatric patients [see WARNINGS AND PRECAUTIONS (5.10), USE IN SPECIFIC POPULATIONS (8.4), and CLINICAL STUDIES (14.9)]. Prolonged levofloxacin tablets therapy should only be used when the benefit outweighs the risk. à Drug administration should begin as soon as possible after suspected or confirmed exposure to Yersinia pestis. Higher doses of levofloxacin tablets typically used for treatment of pneumonia can be used for treatment of plague, if clinically indicated. 2.2 Dosage in Pediatric Patients The dosage in pediatric patients ≥ 6 months of age is described below in Table 2.

Careful clinical observation and appropriate laboratory studies should be performed prior to and during therapy since elimination of levofloxacin may be reduced. No adjustment is necessary for patients with a creatinine clearance ≥ 50 mL/min. In patients with impaired renal function (creatinine clearance <50 mL/min), adjustment of the dosage regimen is necessary to avoid the accumulation of levofloxacin due to decreased clearance [see USE IN SPECIFIC POPULATIONS (8.6)]. Table 3 shows how to adjust dose based on creatinine clearance. Table 3: Dosage Adjustment in Adult Patients with Renal Impairment (creatinine clearance <50 mL/min) Dosage in Normal Renal Function Every 24 hours Creatinine Clearance 20 to 49 mL/min Creatinine Clearance 10 to 19 mL/min Hemodialysis or Chronic Ambulatory Peritoneal Dialysis (CAPD) 750 mg 750 mg every 48 hours 750 mg initial dose, then 500 mg every 48 hours 750 mg initial dose, then 500 mg every 48 hours 500 mg 500 mg initial dose, then 250 mg every 24 hours 500 mg initial dose, then 250 mg every 48 hours 500 mg initial dose, then 250 mg every 48 hours 250 mg No dosage adjustment required 250 mg every 48 hours. If treating uncomplicated UTI, then no dosage adjustment is required No information on dosing adjustment is available 2.4 Drug Interaction With Chelation Agents: Antacids, Sucralfate, Metal Cations, Multivitamins Levofloxacin tablets should be administered at least two hours before or two hours after antacids containing magnesium, aluminum, as well as sucralfate, metal cations such as iron, and multivitamin preparations with zinc or didanosine chewable/buffered tablets or the pediatric powder for oral solution [see DRUG INTERACTIONS (7.1) and PATIENT COUNSELING INFORMATION (17.2)]. 2.5 Administration Instructions Food and Levofloxacin Tablets Levofloxacin tablets can be administered without regard to food. Hydration for Patients Receiving Levofloxacin Tablets Adequate hydration of patients receiving oral levofloxacin tablets should be maintained to prevent the formation of highly concentrated urine. Crystalluria and cylindruria have been reported with quinolones [see ADVERSE REACTIONS (6.1) and PATIENT COUNSELING INFORMATION (17.2)].
