4 Contraindications

Known hypersensitivity (e.g., anaphylaxis) to cefuroxime axetil tablets or to other β-lactams (e.g., penicillins and cephalosporins). ( 4)

Cefuroxime axetil tablets are contraindicated in patients with a known hypersensitivity (e.g., anaphylaxis) to cefuroxime axetil or to other β-lactam antibacterial drugs (e.g., penicillins and cephalosporins).

5 Warnings And Precautions

Serious hypersensitivity (anaphylactic) reactions: In the event of a serious reaction, discontinue cefuroxime axetil tablets and institute appropriate therapy. ( 5.1)

Clostridium difficile- associated diarrhea (CDAD): If diarrhea occurs, evaluate patients for CDAD. ( 5.2)

5.1 Anaphylactic Reactions
Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients on β-lactam antibacterials. These reactions are more likely to occur in individuals with a history of β-lactam hypersensitivity and/or a history of sensitivity to multiple allergens. There have been reports of individuals with a history of penicillin hypersensitivity who have experienced severe reactions when treated with cephalosporins. Cefuroxime axetil tablets are contraindicated in patients with a known hypersensitivity to cefuroxime axetil or other β-lactam antibacterial drugs [ see Contraindications (4)] . Before initiating therapy with cefuroxime axetil tablets, inquire about previous hypersensitivity reactions to penicillins, cephalosporins, or other allergens. If an allergic reaction occurs, discontinue cefuroxime axetil tablets and institute appropriate therapy.

5.2 Clostridium difficile-Associated Diarrhea
Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including cefuroxime axetil tablets, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.

C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin-producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over 2 months after the administration of antibacterial agents.

If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.

5.3 Potential for Microbial Overgrowth
The possibility of superinfections with fungal or bacterial pathogens should be considered during therapy.

5.4 Development of Drug-Resistant Bacteria
Prescribing cefuroxime axetil tablets either in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.

5.6 Interference with Glucose Tests
A false-positive result for glucose in the urine may occur with copper reduction tests, and a false-negative result for blood/plasma glucose may occur with ferricyanide tests in subjects receiving cefuroxime axetil tablets [ see Drug Interactions (7.4)] .

6 Adverse Reactions

The most common adverse reactions (≥3%) for cefuroxime axetil tablets are diarrhea, nausea/vomiting, Jarisch-Herxheimer reaction, and vaginitis (early Lyme disease). ( 6.1)

To report SUSPECTED ADVERSE REACTIONS, contact Wockhardt USA LLC. at 1-800-346-6854 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

The following serious and otherwise important adverse reaction is described in greater detail in the Warnings and Precautions section of the label:

Anaphylactic Reactions [ see Warnings and Precautions (5.1)]

6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Tablets

Multiple-Dose Dosing Regimens with 7 to 10 Days' Duration: In multiple-dose clinical trials, 912 subjects were treated with cefuroxime axetil tablets (125 to 500 mg twice daily). It is noted that 125 mg twice daily is not an approved dosage. Twenty (2.2%) subjects discontinued medication due to adverse reactions. Seventeen (85%) of the 20 subjects who discontinued therapy did so because of gastrointestinal disturbances, including diarrhea, nausea, vomiting, and abdominal pain. The percentage of subjects treated with cefuroxime axetil tablets who discontinued study drug because of adverse reactions was similar at daily doses of 1,000, 500, and 250 mg (2.3%, 2.1%, and 2.2%, respectively). However, the incidence of gastrointestinal adverse reactions increased with the higher recommended doses.

The adverse reactions in Table 5 are for subjects (n = 912) treated with cefuroxime axetil tablets in multiple-dose clinical trials.

7 Drug Interactions

Oral Contraceptives: Effects on gut flora may lower estrogen reabsorption and reduce efficacy of oral contraceptives. ( 7.1)

Drugs that reduce gastric acidity may lower the bioavailability of cefuroxime axetil tablets. ( 7.2)

Coadministration with probenecid increases systemic exposure to cefuroxime axetil tablets and is therefore not recommended. ( 7.3)

7.1 Oral Contraceptives
Cefuroxime axetil may affect the gut flora, leading to lower estrogen reabsorption and reduced efficacy of combined oral estrogen/progesterone contraceptives. Counsel patients to consider alternate supplementary (non-hormonal) contraceptive measures during treatment.

7.2 Drugs that Reduce Gastric Acidity
Drugs that reduce gastric acidity may result in a lower bioavailability of cefuroxime axetil tablets compared with administration in the fasting state. Administration of drugs that reduce gastric acidity may negate the food effect of increased absorption of cefuroxime axetil tablets when administered in the postprandial state. Administer cefuroxime axetil tablets at least 1 hour before or 2 hours after administration of short-acting antacids. Histamine-2 (H ₂) antagonists and proton pump inhibitors should be avoided.

7.3 Probenecid
Concomitant administration of probenecid with cefuroxime axetil tablets increases serum concentrations of cefuroxime [ see Clinical Pharmacology (12.3)]. Co-administration of probenecid with cefuroxime axetil is not recommended.

7.4 Drug/Laboratory Test Interactions
A false-positive reaction for glucose in the urine may occur with copper reduction tests (e.g., Benedict's or Fehling's solution), but not with enzyme-based tests for glycosuria. As a false-negative result may occur in the ferricyanide test, it is recommended that either the glucose oxidase or hexokinase method be used to determine blood/plasma glucose levels in patients receiving cefuroxime axetil. The presence of cefuroxime does not interfere with the assay of serum and urine creatinine by the alkaline picrate method.

8 Use In Specific Populations

8.1 Pregnancy
Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, cefuroxime axetil tablets should be used during pregnancy only if clearly needed.

Reproduction studies have been performed in mice at doses up to 3,200 mg/kg/day (14 times the recommended maximum human dose based on body surface area) and in rats at doses up to 1,000 mg/kg/day (9 times the recommended maximum human dose based on body surface area) and have revealed no evidence of impaired fertility or harm to the fetus due to cefuroxime axetil.

8.3 Nursing Mothers
Because cefuroxime is excreted in human milk, caution should be exercised when cefuroxime axetil is administered to a nursing woman.

8.4 Pediatric Use
The safety and effectiveness of cefuroxime axetil tablets have been established for pediatric patients aged 3 months to 12 years for acute bacterial maxillary sinusitis based upon its approval in adults. Use of cefuroxime axetil tablets in pediatric patients is supported by pharmacokinetic and safety data in adults and pediatric patients, and by clinical and microbiological data from adequate and well-controlled trials of the treatment of acute bacterial maxillary sinusitis in adults and of acute otitis media with effusion in pediatric patients. It is also supported by postmarketing adverse events surveillance. [ See Indications and Usage (1), Dosage and Administration (2), Adverse Reactions (6), Clinical Pharmacology (12.3).]

8.5 Geriatric Use
Of the total number of subjects who received cefuroxime axetil tablets in 20 clinical trials, 375 were aged 65 and older while 151 were aged 75 and older. No overall differences in safety or effectiveness were observed between these subjects and younger adult subjects. Reported clinical experience has not identified differences in responses between the elderly and younger adult patients, but greater sensitivity of some older individuals cannot be ruled out.

Cefuroxime is substantially excreted by the kidney, and the risk of adverse reactions may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

8.6 Renal Impairment
Reducing the dosage of cefuroxime axetil tablets is recommended for adult patients with severe renal impairment (creatinine clearance <30 mL/min) [ see Dosage and Administration (2.5), Clinical Pharmacology (12.3)] .

10 Overdosage

Overdosage of cephalosporins can cause cerebral irritation leading to convulsions or encephalopathy. Serum levels of cefuroxime can be reduced by hemodialysis and peritoneal dialysis.

11 Description

Cefuroxime axetil tablets, USP contain cefuroxime as cefuroxime axetil. Cefuroxime axetil is a semisynthetic, cephalosporin antibacterial drug for oral administration.

The chemical name of cefuroxime axetil (1-(acetyloxy) ethyl ester of cefuroxime) is ( RS)-1-hydroxyethyl (6 R,7 R)-7-[2-(2-furyl)glyoxyl-amido]-3-(hydroxymethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]-oct-2-ene-2-carboxylate, 7 ²-( Z)-( O-methyl-oxime), 1-acetate 3-carbamate. Its molecular formula is C ₂₀H ₂₂N ₄O ₁₀S, and it has a molecular weight of 510.48.

Cefuroxime axetil is in the amorphous form and has the following structural formula:
Cefuroxime axetil tablets, USP are film-coated and contain the equivalent of 125, 250, or 500 mg of cefuroxime as cefuroxime axetil. Cefuroxime axetil tablets, USP contain the inactive ingredients colloidal silicon dioxide, prosolv SMCC 50, sodium lauryl sulfate, croscarmellose sodium, hydrogenated castor oil, hypromellose, propylene glycol, titanium dioxide, dewaxed shellac powder, dibutyl sebacate and polysorbate 80.

12 Clinical Pharmacology

12.1 Mechanism of Action
Cefuroxime axetil is an antibacterial drug [ see Clinical Pharmacology (12.4)].

12.3 Pharmacokinetics
Absorption

After oral administration, cefuroxime axetil is absorbed from the gastrointestinal tract and rapidly hydrolyzed by nonspecific esterases in the intestinal mucosa and blood to cefuroxime. Serum pharmacokinetic parameters for cefuroxime following administration of cefuroxime axetil tablets to adults are shown in Table 8.

Table 8. Pharmacokinetics of Cefuroxime Administered in the Postprandial State as Cefuroxime Axetil Tablets to Adults ^a
^a Mean values of 12 healthy adult volunteers.

^b Drug administered immediately after a meal.

Dose ^b ( Cefuroxime Equivalent ) Peak Plasma Concentration ( mcg / mL ) Time of Peak Plasma Concentration ( h ) Mean Elimination Half - life ( h ) AUC ( mcg( h / mL )

125 mg 2.1 2.2 1.2 6.7

250 mg 4.1 2.5 1.2 12.9

500 mg 7 3 1.2 27.4

1,000 mg 13.6 2.5 1.3 50

Food Effect: Absorption of the tablet is greater when taken after food (absolute bioavailability increases from 37% to 52%). Despite this difference in absorption, the clinical and bacteriologic responses of subjects were independent of food intake at the time of tablet administration in 2 trials where this was assessed.

All pharmacokinetic and clinical effectiveness and safety trials in pediatric subjects using the suspension formulation were conducted in the fed state. No data are available on the absorption kinetics of the suspension formulation when administered to fasted pediatric subjects.

Lack of Bioequivalence: Oral suspension was not bioequivalent to tablets when tested in healthy adults. The tablet and oral suspension formulations are NOT substitutable on a milligram-per-milligram basis. The area under the curve for the suspension averaged 91% of that for the tablet, and the peak plasma concentration for the suspension averaged 71% of the peak plasma concentration of the tablets. Therefore, the safety and effectiveness of both the tablet and oral suspension formulations were established in separate clinical trials.

Distribution

Cefuroxime is distributed throughout the extracellular fluids. Approximately 50% of serum cefuroxime is bound to protein.

Metabolism

The axetil moiety is metabolized to acetaldehyde and acetic acid.

Excretion

Cefuroxime is excreted unchanged in the urine; in adults, approximately 50% of the administered dose is recovered in the urine within 12 hours. The pharmacokinetics of cefuroxime in pediatric subjects have not been studied. Until further data are available, the renal elimination of cefuroxime axetil established in adults should not be extrapolated to pediatric subjects.

Specific Populations

Renal Impairment: In a trial of 28 adults with normal renal function or severe renal impairment (creatinine clearance <30 mL/min), the elimination half-life was prolonged in relation to severity of renal impairment. Prolongation of the dosage interval is recommended in adult patients with creatinine clearance <30 mL/min [ see Dosage and Administration (2.5)] .

Geriatric Patients: In a trial of 20 elderly subjects (mean age = 83.9 years) having a mean creatinine clearance of 34.9 mL/min, the mean serum elimination half-life was prolonged to 3.5 hours; however, despite the lower elimination of cefuroxime in geriatric patients, dosage adjustment based on age is not necessary [ see Use in Specific Populations (8.5)] .

Drug Interactions

Concomitant administration of probenecid with cefuroxime axetil tablets increases the cefuroxime area under the serum concentration versus time curve and maximum serum concentration by 50% and 21%, respectively.

12.4 Microbiology
Mechanism of Action

Cefuroxime axetil is a bactericidal agent that acts by inhibition of bacterial cell wall synthesis. Cefuroxime axetil has activity in the presence of some β-lactamases, both penicillinases and cephalosporinases, of gram-negative and gram-positive bacteria.

Mechanism of Resistance

Resistance to cefuroxime axetil is primarily through hydrolysis by β-lactamase, alteration of penicillin-binding proteins (PBPs), decreased permeability, and the presence of bacterial efflux pumps.

Susceptibility to cefuroxime axetil will vary with geography and time; local susceptibility data should be consulted, if available. Beta-lactamase -negative, ampicillin-resistant (BLNAR) isolates of H. influenzae should be considered resistant to cefuroxime axetil.

Cefuroxime axetil has been shown to be active against most isolates of the following bacteria, both in vitro and in clinical infections [ see Indications and Usage (1)] :

Gram-positive bacteria

Staphylococcus aureus (methicillin-susceptible isolates only)

Streptococcus pneumoniae

Streptococcus pyogenes

Gram-negative bacteria

Escherichia coli ^a

Klebsiella pneumoniae ^a

Haemophilus influenzae

Haemophilus parainfluenzae

Moraxella catarrhalis

Neisseria gonorrhoeae

^a Most extended spectrum β-lactamase (ESBL) -producing and carbapenemase-producing isolates are resistant to cefuroxime axetil.

Spirochetes

Borrelia burgdorferi

The following in vitro data are available, but their clinical significance is unknown. At least 90 percent of the following microorganisms exhibit an in vitro minimum inhibitory concentration (MIC) less than or equal to the susceptible breakpoint for cefuroxime axetil of 1 mcg/mL. However, the efficacy of cefuroxime axetil in treating clinical infections due to these microorganisms has not been established in adequate and well-controlled clinical trials.

Susceptibility Test Methods

When available, the clinical microbiology laboratory should provide the results of in vitro susceptibility tests for antimicrobial drug products used in local hospitals and practice areas to the physician as periodic reports that describe the susceptibility profile of nosocomial and community-acquired pathogens. These reports should aid the physician in selecting an antibacterial drug product for treatment.

Dilution Techniques: Quantitative methods are used to determine antimicrobial MICs. These MICs provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. The MICs should be determined using a standardized test method (broth or agar). ^1,2The MIC values should be interpreted according to criteria provided in Table 10. ^2,3

Diffusion Techniques: Quantitative methods that require measurement of zone diameters also provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. The zone size provides an estimate of the susceptibility of bacteria to antimicrobial compounds. The zone size should be determined using a standardized test method. ⁴This procedure uses paper disks impregnated with 30 mcg cefuroxime axetil to test the susceptibility of microorganisms to cefuroxime axetil. The disk diffusion interpretive criteria are provided in Table 10. ³

Table 10. Susceptibility Test Interpretive Criteria for Cefuroxime Axetil
^a For Enterobacteriaceae, Haemophilus spp., and Moraxella catarrhalis, susceptibility interpretive criteria are based on a dose of 500 mg every 12 hours in patients with normal renal function.

^b Haemophilus spp. includes only isolates of H . influenzae and H . parainfluenzae.

Pathogen Minimum Inhibitory Concentrations ( mcg / mL ) Disk Diffusion Zone Diameters ( mm )

( S ) Susceptible ( I ) Intermediate ( R ) Resistant ( S ) Susceptible ( I ) Intermediate ( R ) Resistant

Enterobacteriaceae ^a ≤4 8 to 16 ≥32 ≥23 15 to 22 ≤14

Haemophilus spp. ^a ^, ^b ≤4 8 ≥16 ≥20 17 to 19 ≤16

Moraxella catarrhalis ^a ≤4 8 ≥16 - - -

Streptococcus pneumoniae ≤1 2 ≥4 - - -

Susceptibility of staphylococci to cefuroxime may be deduced from testing only penicillin and either cefoxitin or oxacillin.

Susceptibility of Streptococcus pyogenes may be deduced from testing penicillin. ³

A report of "Susceptible" indicates that the antimicrobial drug is likely to inhibit growth of the pathogen if the antimicrobial drug reaches the concentration usually achievable at the site of infection. A report of "Intermediate" indicates that the result should be considered equivocal, and if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where a high dosage of drug can be used. This category also provides a buffer zone that prevents small uncontrolled technical factors from causing major discrepancies in interpretation. A report of "Resistant" indicates that the antimicrobial drug is not likely to inhibit growth of the pathogen if the antimicrobial drug reaches the concentrations usually achievable at the infection site; other therapy should be selected.

Quality Control: Standardized susceptibility test procedures require the use of laboratory controls to monitor and ensure the accuracy and precision of supplies and reagents used in the assay, and the techniques of the individual performing the test. ^1,2,4 The QC ranges for MIC and disk diffusion testing using the 30-mcg disk are provided in Table 11. ³

13 Nonclinical Toxicology

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Although lifetime studies in animals have not been performed to evaluate carcinogenic potential, no mutagenic activity was found for cefuroxime axetil in a battery of bacterial mutation tests. Positive results were obtained in an in vitro chromosome aberration assay; however, negative results were found in an in vivo micronucleus test at doses up to 1.5 g/kg. Reproduction studies in rats at doses up to 1,000 mg/kg/day (9 times the recommended maximum human dose based on body surface area) have revealed no impairment of fertility.

14 Clinical Studies

14.1 Acute Bacterial Maxillary Sinusitis
One adequate and well-controlled trial was performed in subjects with acute bacterial maxillary sinusitis. In this trial, each subject had a maxillary sinus aspirate collected by sinus puncture before treatment was initiated for presumptive acute bacterial sinusitis. All subjects had radiographic and clinical evidence of acute maxillary sinusitis. In the trial, the clinical effectiveness of cefuroxime axetil tablets in treating acute maxillary sinusitis was comparable to an oral antimicrobial agent containing a specific β-lactamase inhibitor. However, microbiology data demonstrated cefuroxime axetil tablets to be effective in treating acute bacterial maxillary sinusitis due only to Streptococcus pneumoniae or non-β-lactamase-producing Haemophilus influenzae. Insufficient numbers of β-lactamase-producing Haemophilus influenzae and Moraxella catarrhalis isolates were obtained in this trial to adequately evaluate the effectiveness of cefuroxime axetil tablets in treating acute bacterial maxillary sinusitis due to these 2 organisms.

This trial randomized 317 adult subjects, 132 subjects in the U.S. and 185 subjects in South America. Table 12 shows the results of the intent-to-treat analysis.

^a 95% confidence interval around the success difference [-0.08, +0.32].

^b 95% confidence interval around the success difference [-0.10, +0.16].

^c Control was an antibacterial drug containing a β-lactamase inhibitor.

Clinical success (cure + improvement) 65% 53% 77% 74%

Clinical cure 53% 44% 72% 64%

Clinical improvement 12% 9% 5% 10%

In this trial and in a supporting maxillary puncture trial, 15 evaluable subjects had non-β-lactamase-producing Haemophilus influenzae as the identified pathogen. Of these, 67% (10/15) had this pathogen eradicated. Eighteen (18) evaluable subjects had Streptococcus pneumoniae as the identified pathogen. Of these, 83% (15/18) had this pathogen eradicated.

14.2 Early Lyme Disease
Two adequate and well-controlled trials were performed in subjects with early Lyme disease. All subjects presented with physician-documented erythema migrans, with or without systemic manifestations of infection. Subjects were assessed at 1 month posttreatment for success in treating early Lyme disease (Part I) and at 1 year posttreatment for success in preventing the progression to the sequelae of late Lyme disease (Part II).

A total of 355 adult subjects (181 treated with cefuroxime axetil and 174 treated with doxycycline) were randomized in the 2 trials, with diagnosis of early Lyme disease confirmed in 79% (281/355). The clinical diagnosis of early Lyme disease in these subjects was validated by 1) blinded expert reading of photographs, when available, of the pretreatment erythema migrans skin lesion, and 2) serologic confirmation (using enzyme-linked immunosorbent assay [ELISA] and immunoblot assay ["Western" blot]) of the presence of antibodies specific to Borrelia burgdorferi, the etiologic agent of Lyme disease. The efficacy data in Table 13 are specific to this "validated" patient subset, while the safety data below reflect the entire patient population for the 2 trials. Clinical data for evaluable subjects in the "validated" patient subset are shown in Table 13.

Cefuroxime axetil tablets and doxycycline were effective in prevention of the development of sequelae of late Lyme disease.

While the incidence of drug-related gastrointestinal adverse reactions was similar in the 2 treatment groups (cefuroxime axetil - 13%; doxycycline - 11%), the incidence of drug-related diarrhea was higher in the cefuroxime axetil arm versus the doxycycline arm (11% versus 3%, respectively).

17 Patient Counseling Information

Allergic Reactions

Inform patients that cefuroxime axetil tablets is a cephalosporin that can cause allergic reactions in some individuals [ see Warnings and Precautions (5.1)] .

Clostridium difficile -Associated Diarrhea

Inform patients that diarrhea is a common problem caused by antibacterials, and it usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibacterials, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as 2 or more months after having taken their last dose of the antibacterial. If this occurs, advise patients to contact their physician as soon as possible.

Crushing Tablets

Instruct patients to swallow the tablet whole, without crushing the tablet. Patients who cannot swallow the tablet whole should receive the oral suspension.

Drug Resistance

Inform patients that antibacterial drugs, including cefuroxime axetil tablets, should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When cefuroxime axetil tablets are prescribed to treat a bacterial infection, inform patients that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may: (1) decrease the effectiveness of the immediate treatment, and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by cefuroxime axetil tablets or other antibacterial drugs in the future.
