5 WARNINGS AND PRECAUTIONS
5.1 Hypersensitivity Reactions
Allergic reactions in the form of rash, urticaria, angioedema, anaphylaxis, erythema multiforme, Stevens- Johnson syndrome, or toxic epidermal necrolysis have been reported with the use of Cendalex. Before therapy with Cendalex is instituted, inquire whether the patient has a history of hypersensitivity reactions to Cendalex, cephalosporins, penicillins, or other drugs. Cross-hypersensitivity among beta-lactam antibacterial drugs may occur in up to 10% of patients with a history of penicillin allergy.
If an allergic reaction to Cendalex occurs, discontinue the drug and institute appropriate treatment.
5.2 Clostridium difficile-Associated Diarrhea
Clostridium difficile-associated diarrhea has been reported with use of nearly all antibacterial agents, including Cendalex, 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 two 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 Direct Coombs’ Test Seroconversion
Positive direct Coombs’ tests have been reported during treatment with the cephalosporin antibacterial drugs including Cendalex. Acute intravascular hemolysis induced by Cendalex therapy has been reported. If anemia develops during or after Cendalex therapy, perform a diagnostic work-up for drug-induced hemolytic anemia, discontinue Cendalex and institute appropriate therapy.
5.4 Seizure Potential
Several cephalosporins have been implicated in triggering seizures, particularly in patients with renal impairment when the dosage was not reduced. If seizures occur, discontinue Cendalex. Anticonvulsant therapy can be given if clinically indicated.
5.5 Prolonged Prothrombin Time
Cephalosporins may be associated with prolonged prothrombin time. Those at risk include patients with renal or hepatic impairment, or poor nutritional state, as well as patients receiving a protracted course of antibacterial therapy, and patients receiving anticoagulant therapy. Monitor prothrombin time in patients at risk and manage as indicated.
5.6 Development of Drug-Resistant Bacteria
Prescribing Cendalex in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
Prolonged use of Cendalex may result in the overgrowth of nonsusceptible organisms. Careful observation of the patient is essential. If superinfection occurs during therapy, appropriate measures should be taken.
6 ADVERSE REACTIONS
The following serious events are described in greater detail in the Warning and Precautions section:
The most common adverse reactions associated with Cendalex include diarrhea, nausea, vomiting, dyspepsia and abdominal pain. ( 6)

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 to rates in the clinical trials of another drug and may not reflect the rates observed in practice
In clinical trials, the most frequent adverse reaction was diarrhea. Nausea and vomiting, dyspepsia, gastritis, and abdominal pain have also occurred. As with penicillins and other cephalosporins, transient hepatitis and cholestatic jaundice have been reported.
Other reactions have included hypersensitivity reactions, genital and anal pruritus, genital candidiasis, vaginitis and vaginal discharge, dizziness, fatigue, headache, agitation, confusion, hallucinations, arthralgia, arthritis, and joint disorder. Reversible interstitial nephritis has been reported. Eosinophilia, neutropenia, thrombocytopenia, hemolytic anemia, and slight elevations in aspartate transaminase (AST) and alanine transaminase (ALT) have been reported.
In addition to the adverse reactions listed above that have been observed in patients treated with Cendalex, the following adverse reactions and other altered laboratory tests have been reported for cephalosporin class antibacterial drugs:
Other Adverse Reactions: Fever, colitis, aplastic anemia, hemorrhage, renal dysfunction, and toxic nephropathy.
Altered Laboratory Tests:Prolonged prothrombin time, increased blood urea nitrogen (BUN), increased creatinine, elevated alkaline phosphatase, elevated bilirubin, elevated lactate dehydrogenase (LDH), pancytopenia, leukopenia, and agranulocytosis.
7 DRUG INTERACTIONS
Administration of Cendalex with metformin results in increased plasma metformin concentrations and decreased renal clearance of metformin.
Careful patient monitoring and dose adjustment of metformin is recommended in patients concomitantly taking Cendalex and metformin [ see Clinical Pharmacology (12.2) ].
The renal excretion of Cendalex is inhibited by probenecid. Co-administration of probenecid with Cendalex is not recommended.
7.3 Interaction With Laboratory or Diagnostic Testing
A false-positive reaction may occur when testing for the presence of glucose in the urine using Benedict’s solution or Fehling’s solution.
8 USE IN SPECIFIC POPULATIONS
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, this drug should be used during pregnancy only if clearly needed.
Reproduction studies have been performed on mice and rats using oral doses of Cendalex monohydrate 0.6 and 1.5 times the maximum daily human dose based upon body surface area basis, and have revealed no evidence of impaired fertility or harm to the fetus.
8.3 Nursing Mothers
Cendalex is excreted in human milk. Caution should be exercised when Cendalex is administered to a nursing woman.
8.4 Pediatric Use
The safety and effectiveness of Cendalex in pediatric patients was established in clinical trials for the dosages described in the dosage and administration section [see Dosage and Administration ] .
8.5 Geriatric Use
Of the 701 subjects in 3 published clinical studies of Cendalex, 433 (62%) were 65 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients.
This drug is substantially excreted by the kidney, and the risk of toxic reactions to this drug 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 [ see Warnings and Precautions ( 5.4 ) ].
8.6 Renal Impairment
Cendalex should be administered with caution in the presence of impaired renal function (creatinine clearance < 30 mL/min, with or without dialysis). Under such conditions, careful clinical observation and laboratory studies renal function monitoring should be conducted because safe dosage may be lower than that usually recommended .
Symptoms of oral overdose may include nausea, vomiting, epigastric distress, diarrhea, and hematuria. In the event of an overdose, institute general supportive measures.
Forced diuresis, peritoneal dialysis, hemodialysis, or charcoal hemoperfusion have not been established as beneficial for an overdose of Cendalex.

12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Cendalex is a cephalosporin antibacterial drug [seeMicrobiology ] .
Cendalex is acid stable and may be given without regard to meals. Following doses of 250 mg, 500 mg, and 1 g, average peak serum levels of approximately 9, 18, and 32 mcg/mL, respectively, were obtained at 1 hour. Serum levels were detectable 6 hours after administration (at a level of detection of 0.2 mcg/mL).
Cendalex is approximately 10% to 15% bound to plasma proteins.
Cendalex is excreted in the urine by glomerular filtration and tubular secretion. Studies showed that over 90% of the drug was excreted unchanged in the urine within 8 hours. During this period, peak urine concentrations following the 250 mg, 500 mg, and 1 g doses were approximately 1000, 2200, and 5000 mcg/mL respectively.
In healthy subjects given single 500 mg doses of Cendalex and metformin, plasma metformin mean Cmax and AUC increased by an average of 34% and 24%, respectively, and metformin mean renal clearance decreased by 14%. No information is available about the interaction of Cendalex and metformin following multiple doses of either drug.
Mechanism of Action
Cendalex is a bactericidal agent that acts by the inhibition of bacterial cell-wall synthesis.
Methicillin-resistant staphylococci and most isolates of enterococci are resistant to Cendalex. Cendalex is not active against most isolates of Enterobacter spp., Morganella morganii, and Proteus vulgaris. Cendalex has no activity against Pseudomonas spp., or Acinetobacter calcoaceticus. Penicillin-resistant Streptococcus pneumoniae is usually cross-resistant to beta-lactam antibacterial drugs.
Cendalex 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) ].
Staphylococcus aureus (methicillin-susceptible isolates only)
Streptococcus pneumoniae (penicillin-susceptible isolates)
Escheric h ia coli
Susceptibility Tests Methods
When available, the clinical microbiology laboratory should provide the results of in vitro susceptibility test results for antimicrobial drug products used in resident hospitals 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.
In cases of uncomplicated urinary tract infection only, susceptibility of E. coli, K. pneumoniae, and P. mirabilis to Cendalex may be inferred by testing cefazolin2.
Quantitative methods are used to determine antimicrobial minimal inhibitory concentrations (MICs). These MICs provide estimates of the susceptibility of bacteria to antimicrobial compounds. The MICs should be determined using a standardized test methods (broth or agar)1,2.
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 method2,3.
A report of Susceptible (S) 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 (I) 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 the 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 (R) 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.
Qualit y Co n t r ol
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 ,2,3,.
