Active ingredients: Cefixime
STADIUM 400 mg film-coated tablets
Why is Stadium used? What is it for?
PHARMACOTHERAPEUTIC CATEGORY
Antibacterial for systemic use, belonging to the class of cephalosporins.
THERAPEUTIC INDICATIONS
STADIUM is indicated in the treatment of infections caused by microorganisms sensitive to cefixime and in particular:
Exacerbations of chronic bronchitis
Community-acquired pneumonia
Uncomplicated infections of the lower urinary tract
Uncomplicated pyelonephritis.
In the treatment of:
Otitis media
Sinusitis
Pharyngitis.
Contraindications When Stadium should not be used
Hypersensitivity to the active substance, to other cephalosporins, to soya or to any of the excipients. The medicine is also generally contraindicated in subjects with hypersensitivity to penicillins and cephalosporins (see "Precautions for use").
Precautions for use What you need to know before taking Stadium
STADIUM should be administered with caution in patients who have shown hypersensitivity to other medicinal products. Cephalosporins should be administered with caution to penicillin sensitive patients, as there is some evidence of partial cross-allergenicity between penicillins and cephalosporins.
Some patients have shown severe reactions (including anaphylaxis) to both drug classes. Particular caution is recommended in patients who have developed allergic reactions to penicillins or other beta-lactam antibiotics, as cross-reactions may occur (for relative contraindications). to known hypersensitivity reactions, see "Contraindications").
If severe hypersensitivity reactions or anaphylactic reactions occur after administration of cefixime, use of cefixime should be discontinued immediately and appropriate emergency measures undertaken.
Kidney failure
STADIUM should be administered with caution to patients with creatinine clearance <20 ml / min (see "Dose, method and time of administration"). There are insufficient data on the use of cefixime in children and adolescents with renal insufficiency. Therefore the use of cefixime is not recommended in these patient groups.
Renal function should be monitored during combination therapy with cefixime and aminoglycoside antibiotics, polymyxin B, colistin or high doses of loop diuretics (eg furosemide) due to the possibility of additional renal impairment. This particularly affects patients. who already have reduced kidney function (see "Interactions").
Interactions Which drugs or foods can modify the effect of Stadium
Tell your doctor or pharmacist if you have recently taken any other medicines, even those without a prescription. Concomitant administration of potentially nephrotoxic substances (such as glycosamide antibiotics, colistin, polymyxin and viomycin) and intensely acting diuretics (e.g. ethacrynic acid or furosemide) leads to an increased risk of impaired renal function (see "Precautions for use" ").
Nifedipine, a calcium channel blocker, can increase the bioavailability of cefixime by up to 70%.
As with other cephalosporins, increases in prothrombin time have been noted in a few patients. Therefore, caution should be exercised in patients on anticoagulant therapy.
Administration of cefixime may reduce the efficacy of oral contraceptives. Therefore, it is recommended to use additional non-hormonal contraceptive measures.
Warnings It is important to know that:
Treatment with STADIUM at the recommended dose (400 mg / day) can significantly alter the normal flora of the colon and lead to superinfection with Clostridium. Studies indicate that a toxin produced by Clostridium difficile is the main cause of antibiotic-associated diarrhea.
In patients who develop severe persistent diarrhea during or after use of cefixime, the risk of life-threatening pseudomembranous colitis should be kept in mind. The use of STADIUM should be discontinued and appropriate treatment measures instituted. . Treatment of pseudomembranous colitis includes sigmoidoscopy, appropriate bacteriological tests, administration of fluid, electrolyte and protein supplements. If colitis does not improve after stopping the drug, or if symptoms are severe, oral vancomycin is the drug of choice for the treatment of antibiotic-associated pseudomembranous colitis produced by C. difficile. Other causes of colitis must be excluded. The use of drugs that inhibit intestinal peristalsis is contraindicated.
Influence on laboratory diagnostic tests
False positive reactions due to the presence of glucose in the urine can occur with Benedict's or Fehling's solutions or with copper sulphate tablets, but not with tests based on enzymatic reactions with glucose oxidase.
False Coombs test positives have been reported during cephalosporin treatment, therefore it should be noted that a positive Coombs test may be due to the drug.
The tablet coating contains 0.6 mg of soy lecithin.
Pregnancy and breastfeeding
Ask your doctor or pharmacist for advice before taking any medicine.
Pregnancy
There are no adequate data on the use of cefixime in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryo-fetal development, parturition or postnatal development. STADIUM should not be used in women. pregnant unless considered essential by your doctor.
Feeding time
There is no data on the passage of the drug into breast milk. Animal studies have shown excretion of cefixime in milk. A decision must be made whether to continue / discontinue breastfeeding or to continue / discontinue cefixime therapy, taking into account the benefit of breastfeeding for the child and the benefit of cefixime therapy for the mother. However, until further clinical experience is available, STADIUM should not be prescribed to women who are breastfeeding.
Effects on the ability to drive a vehicle or use machines
Cefixime has no known effects on the ability to drive and use machines. However, side effects may occur (see also section "Undesirable effects"), which may affect the ability to drive or use machines.

The usual duration of treatment is 7 days. If necessary, it can be continued for up to 14 days.
Elderly patients
Elderly patients can be treated with the same dose as adults. In severe renal impairment, renal function should be evaluated and the dose adjusted (see "Precautions for use").
Adolescents ≥ 12 years of age
Adolescents> 12 years may receive the same recommended dose as adults.
Children from 6 months to 11 years of age
In children from 6 months to 11 years it is recommended to administer cefixime in the form of an oral suspension. The recommended dosage in children is 8 mg / kg / day given as a single dose or in two divided doses.
Children under 6 months of age
The safety and efficacy of cefixime have not been evaluated in children less than 6 months of age.
Kidney failure
STADIUM can be administered in the presence of impaired renal function. The normal dose and treatment schedule can be used in patients with creatinine clearance> 20 ml / minute. In patients with creatinine clearance <20 ml / minute, it is recommended not to exceed a dose of 200 mg once daily. The dose and schedule in patients on chronic outpatient peritoneal dialysis or on hemodialysis should follow the same recommendations as for patients with creatinine clearance less than 20 ml / minute.
There are insufficient data on use in children and adolescents with renal insufficiency. Therefore the use of cefixime is not recommended in these patient groups.
Method of administration

04.3 Contraindications
Hypersensitivity to the active substance, to other cephalosporins, to soya or to any of the excipients. The medicinal product is also generally contraindicated in subjects with hypersensitivity to penicillins and cephalosporins (see section 4.4).
04.4 Special warnings and appropriate precautions for use
STADIUM should be administered with caution in patients who have shown hypersensitivity to other medicinal products. Cephalosporins should be administered with caution to penicillin sensitive patients, as there is some evidence of partial cross-allergenicity between penicillins and cephalosporins.
Some patients have experienced severe reactions (including anaphylaxis) to both drug classes.
Particular caution is recommended in patients who have developed allergic reactions to penicillins or other beta-lactam antibiotics, as cross-reactions may occur (for contraindications related to known hypersensitivity reactions, see section 4.3).
If severe hypersensitivity reactions or anaphylactic reactions occur after administration of cefixime, use of cefixime should be discontinued immediately and appropriate emergency measures undertaken.
Kidney failure
STADIUM should be administered with caution in patients with creatinine clearance
Renal function should be monitored during combination therapy with cefixime and aminoglycoside antibiotics, polymyxin B, colistin or high doses of loop diuretics (eg furosemide) due to the possibility of additional renal impairment. This particularly affects patients. who already have impaired renal function (see section 4.5).
Treatment with STADIUM at the recommended dose (400 mg / day) can significantly alter the normal flora of the colon and lead to superinfection with Clostridium. Studies indicate that a toxin produced by the Clostridium difficile it is the main cause of antibiotic-associated diarrhea.
In patients who develop severe persistent diarrhea during or after use of cefixime, the risk of life-threatening pseudomembranous colitis should be kept in mind. The use of STADIUM should be discontinued and appropriate treatment measures instituted. . Treatment of pseudomembranous colitis includes sigmoidoscopy, appropriate bacteriological tests, administration of fluid, electrolyte and protein supplements. If colitis does not improve after stopping the drug, or if symptoms are severe, oral vancomycin is the drug of choice for the treatment of antibiotic-associated pseudomembranous colitis produced by C. difficult. Other causes of colitis must be excluded. The use of drugs that inhibit intestinal peristalsis is contraindicated.
Influence on laboratory diagnostic tests
False positive reactions due to the presence of glucose in the urine can occur with Benedict's or Fehling's solutions or with copper sulphate tablets, but not with tests based on enzymatic reactions with glucose oxidase.
False Coombs test positives have been reported during cephalosporin treatment, therefore it should be noted that a positive Coombs test may be due to the drug.
The tablet coating contains 0.6 mg of soy lecithin.
04.5 Interactions with other medicinal products and other forms of interaction
Concomitant administration of potentially nephrotoxic substances (such as glycosamide antibiotics, colistin, polymyxin and viomycin) and strongly acting diuretics (e.g. ethacrynic acid or furosemide) leads to an increased risk of impaired renal function (see section 4.4).
Nifedipine, a calcium channel blocker, can increase the bioavailability of cefixime by up to 70%.
As with other cephalosporins, increases in prothrombin time have been noted in a few patients. Therefore, caution should be exercised in patients on anticoagulant therapy.
Administration of cefixime may reduce the efficacy of oral contraceptives. Therefore, it is recommended to use additional non-hormonal contraceptive measures.
04.6 Pregnancy and lactation
Pregnancy
There are no adequate data on the use of cefixime in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryo-fetal development, parturition or postnatal development (see section 5.3). STADIUM must not be used. in pregnant women unless considered essential by the doctor.
Feeding time
There is no data on the passage of the drug into breast milk. Animal studies have shown excretion of cefixime in milk. A decision must be made whether to continue / discontinue breastfeeding or to continue / discontinue cefixime therapy, taking into account the benefit of breastfeeding for the child and the benefit of cefixime therapy for the mother.
However, until further clinical experience is available, STADIUM should not be prescribed to women who are breastfeeding.

05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
Pharmacotherapeutic group: antibacterial for systemic use, belonging to the third generation cephalosporin class.
ATC code: J01DD08.
Mechanism of action:
Cefixime is a new cephalosporin for oral use characterized by a broad spectrum bactericidal activity and by a high resistance to the hydrolytic activity of beta-lactamases.
The bactericidal activity of cefixime is due to the inhibition of the synthesis of the bacterial cell wall.
PK / PD relationship
In PK / PD studies, the time during which plasma concentrations of cefixime exceed the minimum inhibitory concentration (MIC) of the infecting organism was found to correlate better with efficacy.
Resistance mechanism
Bacterial resistance to cefixime may be due to one or more of the following mechanisms:
- Hydrolysis by increased spectrum beta-lactamases and / or chromosome-encoded enzymes (AmpC) which can be induced or de-repressed in some aerobic Gram-negative species
- Reduced affinity to penicillin binding proteins
- Reduced permeability of the outer membrane in certain Gram-negative organisms which restricts access to the proteins that bind penicillins
- Drug efflux pumps.
Several of these resistance mechanisms can coexist in a single bacterial cell. Depending on the mechanism (s) present, bacteria may express cross-resistance to several or all beta-lactam and / or antibacterial drugs of the other classes.
Breakpoints
The minimum inhibitory concentration (MIC) breakpoints, established by EUCAST (May 2009) for cefixime, are as follows:
• H. influenzae: sensitive ≤ 0.12 mg / L, resistant> 0.12 mg / L
• M. catarrhalis: sensitive ≤ 0.5 mg / L, resistant> 1.0 mg / L
• Neisseria gonorrhoeae: sensitive ≤ 0.12 mg / L, resistant> 0.12 mg / L
• Enterobacteriaceae: sensitive ≤ 1.0 mg / L, resistant> 1.0 mg / L (only for uncomplicated urinary tract infections). The breackpoint for theEnterobacteriaceae will discover reduced sensitivities mediated by most clinically important lactamases in Enterobacteriaceae. Occasionally ESBL-producing strains (extended spectrum beta-lactamase) will be considered susceptible. For infection control, epidemiological and surveillance purposes, laboratories may use specific tests to select and confirm ESBL production.
• Non-species related breakpoints: insufficient data.
Sensitivity
The prevalence of resistance may vary geographically and over time for certain species and local information on resistance is desirable, particularly when treating severe infections. As necessary, expert advice should be sought when the local prevalence of resistance is such that the utility of the agent in at least some types of infections is problematic.
+ Cefixime has little activity against staphylococci (regardless of metacillin sensitivity)
§ Intermediate natural sensitivity
% ESBL (extended spectrum beta-lactamase) producing strains are always resistant
& Speed of resistance uncomplicated cystitis, otherwise ≥ 10%.
05.2 Pharmacokinetic properties
Absorption
The absolute oral bioavailability of cefixime is in the range of 22-54%. Absorption is not significantly affected by the presence of food. Cefixime can therefore be given with or without meals.
Distribution
Serum protein binding is well characterized for human and animal serum. Cefixime is almost entirely bound to the albumin fraction, the mean free fraction is 30%. Protein binding of cefixime in human serum is concentration dependent only at very high concentrations, which are not observed after clinical assays.
From studies in vitro, serum or urinary concentrations of 1 mg / l or greater are considered adequate for the most common pathogens against which cefixime is active. Typically, the peak serum levels after the recommended doses in adults and pediatrics lie between 1.5 and 3 mg / l. After multiple dosing there is little or no accumulation of cefixime.
Metabolism and elimination
The pharmacokinetics of cefixime in healthy elderly (age> 64 years) and young volunteers (11-35) are similar to that of a 400 mg once daily dose for 5 days. Mean Cmax and AUC values are slightly higher in the elderly. The elderly may use the same dose as in the general population.
Cefixime is mainly eliminated unchanged in the urine. Glomerular filtration is considered to be the predominant mechanism. Cefixime metabolites have not been isolated from human serum or urine.
Transfer of 14C-labeled cefixime from lactating rats to their offspring via breast milk is quantitatively modest (approximately 1.5% body content of maternal cefixime was found in infants). No data on excretion are available. of cefixime in human milk. Placental transfer of cefixime was small in pregnant rats treated with labeled cefixime.
05.3 Preclinical safety data
There are no results from chronic toxicity studies to suggest that hitherto unknown side effects may occur in humans. in vivo And in vitro did not lead to indications of potential mutagenicity. Long-term carcinogenesis studies have not been conducted.
Reproduction studies were conducted in mice and rats at doses up to 400 times the dose used in humans and revealed no evidence of impaired fertility or harm to the fetus due to cefixime. In rabbits at doses up to 4 times the dose used in humans. "man, there was no evidence of teratogenic effects; there is a high incidence of abortions and maternal deaths, which are an expected consequence of the known sensitivity of rabbits to antibiotic-induced changes in the gut microflora population.
