Такс-О-Бид sodium is indicated for the treatment of the following severe infections when known or thought very likely to be due to organisms that are susceptible to Такс-О-Бид.
â–ª Infections of the lower respiratory tract
â–ª Infections of the kidneys and urinary tract
â–ª Infections of the skin and soft tissue
â–ª Genital infections caused by gonococci, particularly when penicillin has failed or is unsuitable
â–ª Intra-abdominal infections (including Peritonitis)
â–ª Lyme-borreliosis (especially stages II and III)
â–ª Acute Meningitis in case of gram-negative microorganisms in combination with another suitable antibiotic
â–ª Sepsis in case of gram-negative microorganism in combination with another suitable antibiotic
â–ª Endocarditis in case of gram-negative microorganism in combination with another suitable antibiotic
Peri-operative prophylaxis in surgical procedures such as colorectal, gastrointestinal, prostatic, urogenital and gynaecological surgery in patients who have a definite risk of post-operative infections. Такс-О-Бид should be used in combination with another antibiotic that can provide anaerobic cover in the treatment of intra-abdominal infections. Такс-О-Бид should be used in combination with an aminoglycoside in the treatment of infections caused by Pseudomonas.
Protection is best insured by achieving adequate local tissue concentrations at the time contamination is likely to occur.
Administration should usually be stopped within 24 hours since continuing use of any antibiotic in the majority of surgical procedures does not reduce the incidence of subsequent infection.
Такс-О-Бид sodium may be administered intravenously, by bolus injection or infusion, or intramuscularly. The dosage, route and frequency of administration should be determined by the severity of infection, the sensitivity of causative organisms and condition of the patient. Therapy may be initiated before the results of sensitivity tests are known.
The clinician should consult published protocols for information on dosage regimens in specific conditions such as gonorrhoea, Pseudomonas infections and CNS infections.
Dosage and type of administration depend on the severity of the infection, the sensitivity of the bacterium and the condition of the patient.
The duration of the treatment depends on the course of the disease. As a general rule Такс-О-Бид is administered for a further 3 to 4 days after improvement/regression of the symptoms.
Adults and children over 12 years in general receive 1 g Такс-О-Бид every 12 hours. In severe cases, the daily dose can be increased up to 12 g. Daily doses up to 6 g can be divided into at least two individual administrations at 12 hourly intervals. Higher daily doses must be divided into at least 3 to 4 individual administrations at 8 or 6 hour intervals respectively.
The following table may serve as a guide to dosages:
| Type of Infection | Single Dose Такс-О-Бид | Dose Interval | Daily Dose Такс-О-Бид |
| Typical infections, in which sensitivity is demonstrated and bacterium is proven or suspected | 1 g | 12 h | 2 g |
| Infections, in which various bacteria with high to medium sensitivity are demonstrated or suspected | 2 g | 12 h | 4 g |
| Unclear bacterial illness which cannot be localised and where the patient is critically ill | 2 - 3 g | 8 h up to 6 h up to 6 h | 6 g up to 8 g up to 12 g |
For the treatment of gonorrhoea in adults, 1 vial of Такс-О-Бид Sodium for Injection 500mg administered as a single administration.
In most cases due to less sensitive infective bacteria, an increase may be necessary, i.e. 1 g Такс-О-Бид. Examination for syphilis needs to be carried out before commencing therapy.
Perioperative Prophylaxis
For peri-operative infection prophylaxis the administration of a single dose of 1 to 2 g Такс-О-Бид 30 to 60 minutes prior to the operation is recommended. Another antibiotic to cover anaerobic organisms is necessary. A repeat dose is required if the duration of the operation exceeds 90 minutes.
Special Dose Recommendations
Lyme borrelisosis: A daily dose of 6 g Такс-О-Бид (14 to 21 days duration). The daily dose was generally administered divided into 3 parts (2 g Такс-О-Бид 3 times daily).
Infants and children up to 12 years receive 50 to 100 mg Такс-О-Бид according to the severity of the infection (up to 150 mg) per kilogram of body weight per day, divided into equal doses, administered at 12 (up to 6) hour intervals. In individual cases - particularly in life threatening situations - it may be necessary to increase the daily dose to 200 mg Такс-О-Бид per kilogram of body weight.
In neonates and infants doses of 50 mg Такс-О-Бид per kilogram of body weight per day should not be exceeded in view of not fully matured kidney clearance.
In case of life-threatening situations it may be necessary to increase the daily dose.
In those situations the following table is recommended.
| Age | Daily Dose of Такс-О-Бид |
| 0 - 7 days | 50 mg/kg every 12 hours IV |
| 7 days - 1 month | 50 mg/kg every 8 hours IV |
| > 1 month | 75 mg/kg every 8 hours IV |
It is not necessary to differentiate between premature and normal-gestational age infants.
Dosage in the Case of Impaired Renal Function
With patients with a creatinine clearance of 20ml/minute or less, the maintenance dose is reduced to half the normal dose. With patients with a creatinine clearance of 5 ml/minute or less, a reduction of the maintenance dose to 1 g Такс-О-Бид (divided into 2 individual administrations at 12 hour intervals), seems to be appropriate. The stated recommendations are based on experiences with adults.
Since Такс-О-Бид is to a large extent eliminated by haemodialysis, an additional dose should be administered to patients who are dialysed, after the dialysis procedure.
Elderly Patients
No dosage adjustments are needed in patients with normal function.
Other Advice
Electrolyte content of the injections solutions: Since Такс-О-Бид is available as the sodium salt, the sodium content per dose should be taken into account within the framework of the overall therapy and with special balance checks.
Basis for calculation: 1 g Такс-О-Бид (equivalent to 1.04 g Такс-О-Бид sodium) should be calculated as 48 mg sodium equivalent to 2.1 mmol sodium.
Posology and Method of Administration
Intravenous Injection
For IV, Такс-О-Бид Sodium for Injection 500mg is dissolved in at least 2 ml water for injections, Такс-О-Бид Sodium for Injection 1 g in at least 4 ml and subsequently injected directly into the vein over 3 to 5 minutes or after clamping of the infusion tube into the distal end of the tube.
During post-marketing surveillance, potentially life-threatening arrhythmia has been reported in a very few patients who received rapid intravenous administration of Такс-О-Бид through a central venous catheter.
Infusion
For brief infusion 2g of Такс-О-Бид Sodium for Injection is dissolved in 100 ml of isotonic sodium chloride or glucose solution and subsequently IV infused over 50 to 60 minutes. Another compatible infusion solution can also be used for the solution.
Intramuscular Injection
For intramuscular injection. Такс-О-Бид Sodium for Injection 500mg is dissolved in 2 ml and Такс-О-Бид Sodium for Injection 1 g in 4 ml water for injections respectively. Afterwards the injection should take place deep into the gluteal muscle. Pain with the IM injection can be avoided by dissolving Такс-О-Бид Sodium for Injection 500mg in 2ml or Такс-О-Бид Sodium for Injection 1 g in 4 ml 1% lidocaine solution. An intravascular injection is to be avoided in this case, since with intravascular administration lidocaine may lead to unrest, tachycardia, disturbances of cardiac conduction as well as vomiting and cramp. Такс-О-Бид reconstituted with lidocaine should not be administered to infants under 30 months.
It is recommended that no more than 4 ml be injected unilaterally. If the daily dose exceeds 2 g Такс-О-Бид or if Такс-О-Бид is injected more frequently than twice per day, the IV route is recommended.
Combination Therapy
Combination therapy of Такс-О-Бид with aminoglycosides is indicated without availability of an antibiogram in the case of severe, life-threatening infections. Kidney function must be watched in such combination usage. Такс-О-Бид and aminoglycosides should not be mixed in the same syringe or infusion fluid.
In cases of infections with Pseudomonas aeruginosa combination with other antibiotics effective against Pseudomonas can also be indicated.
For infection prophylaxis (peri-operative prophylaxis in surgical procedures such as colorectal, gastro-intestinal, prostatic, urogenital, obstetric and gynaecological surgery) in patients with weakened defence mechanisms, combination can also be indicated with other suitable antibiotics.
Known or suspected hypersensitivity to Такс-О-Бид or other cephalosporins. Allergic cross-reactions can exist between penicillins and cephalosporins.
Такс-О-Бид constituted with Lidocaine Injection BP must never be used:
- by the intravenous route
- in infants under 30 months of age
- in subjects with a previous history of hypersensitivity to Lidocaine or other local anaesthetics of the amide type
- in patients who have a non-paced heart block
- in patients with severe heart failure.
As with other antibiotics, the use of Такс-О-Бид, especially if prolonged, may result in overgrowth of non-susceptible organisms. Repeated evaluation of the patients condition is essential. If superinfection occurs during treatment, appropriate measures should be taken.
Anaphylactic reactions
Такс-О-Бид should be used with caution in persons with a history of allergies or asthma.
Preliminary enquiry about hypersensitivity to penicillin and other β-lactam antibiotics is necessary before prescribing cephalosporins since cross allergy occurs in 5-10% of cases. Use of cephalosporins should be undertaken with extreme caution in penicillin-sensitive subjects
Hypersensitivity reactions (anaphylaxis) occurring with the two types of antibiotics can be serious and occasionally fatal. If a hypersensitivity reaction occurs, treatment must be stopped.
The use of Такс-О-Бид is strictly contraindicated in subjects with a history of immediate-type hypersensitivity to cephalosporins.
Serious bullous reactions
Cases of serious bullous skin reactions such as Stevens-Johnson syndrome or toxic epidermal necrolysis have been reported with Такс-О-Бид. Patients should be advised to contact their doctor immediately prior to continuing treatment if skin and/or mucosal reactions occur.
Clostridium difficile associated disease (e.g. pseudomembranous colitis)
Diarrhoea, particularly if severe and/or persistent, occurring during treatment or in the initial weeks following treatment, may be symptomatic of Clostridium difficile associated disease (CDAD). CDAD may range in severity from mild to life threatening, the most severe form of which is pseudomembranous colitis.
The diagnosis of this rare but potentially fatal condition can be confirmed by endoscopy and/or histology. It is important to consider this diagnosis in patients who present with diarrhoea during or subsequent to the administration of Такс-О-Бид.
If a diagnosis of pseudomembranous colitis is suspected, Такс-О-Бид should be stopped immediately and appropriate specific antibiotic therapy should be started without delay.
Clostridium difficile associated disease can be favoured by faecal stasis. Medicinal products that inhibit peristalsis should not be given.
Haematological reactions
Leucopenia, neutropenia and more rarely, agranulocytosis, may develop during treatment with Такс-О-Бид, particularly if given over long periods. For treatment courses lasting longer than 7-10 days, the blood white cell count should be monitored and treatment stopped in the event of neutropenia.
Some case of eosinophilia and thrombocytopenia, rapidly reversible on stopping treatment, have been reported. Cases of haemolytic anaemia have also been reported.
Patients with renal insufficiency
The dosage should be modified according to the creatinine clearance calculated.
Caution should be exercised if Такс-О-Бид is administered together with aminoglycosides or other nephrotoxic drugs. Renal function must be monitored in these patients, the elderly and those with pre-existing renal impairment.
Neurotoxicity
High doses of beta lactam antibiotics including Такс-О-Бид, particularly in patients with renal insufficiency, may result in encephalopathy (e.g. impairment of consciousness, abnormal movements and convulsions). Patients should be advised to contact their doctor immediately prior to continuing treatment if such reactions occur.
Precautions for administration
During post-marketing surveillance, potentially life-threatening arrhythmia has been reported in a very few patients who received rapid intravenous administration of Такс-О-Бид through a central venous catheter. The recommended time for injection or infusion should be followed.
Effects on Laboratory Tests
As with other cephalosporins, a positive Coombs test has been found in some patients treated with Такс-О-Бид. This phenomenon can interfere with the cross-matching of blood.
Urinary glucose testing with non-specific reducing agents may yield false positive results. This phenomenon is not seen when a glucose-oxidase specific method is used.
Sodium intake
The sodium content of this product (48.2 mg/g) should be taken into account when prescribing to patients requiring sodium restriction.
There is no evidence that Такс-О-Бид impairs the ability to drive or operate machinery.
High doses of Такс-О-Бид, particularly in patients with renal insufficiency, may cause encephalopathy (e.g. impairment of consciousness, abnormal movements and convulsions). Patients should be advised not to drive or operate machinery if any such symptoms occur.
Adverse reactions to Такс-О-Бид sodium have occurred relatively infrequently and have generally been mild and transient.

Jarisch-Herxheimer reaction
For the treatment of borreliosis, a Jarisch-Herxheimer reaction may develop during the first days of treatment. The occurrence of one or more of the following symptoms has been reported after several weeks of treatment of borreliosis: skin rash, itching, fever, leucopenia, increase in liver enzymes, difficulty in breathing, joint discomfort
Hepatobiliary disorders
Increase in liver enzymes (ALAT, ASAT, LDH, gamma-GT and/or alkaline phosphatase) and/or bilirubin have been observed. These laboratory abnormalities may rarely exceed twice the upper limit of the normal range and elicit a pattern of liver injury, usually cholestatic and most often asymptomatic.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the yellow card scheme at: www.mhra.gov.uk/yellowcard
Symptoms of Overdose
Intoxication in the strictest sense, is not known in man. Symptoms of overdose may largely correspond to the profile of side effects. With certain risk patterns and with the administration of very high doses, there is a risk of reversible encephalopathy, central nervous system excitation conditions, myoclonia and cramp, as have been described for other beta lactams. The risk of the appearance of these undesirable effects is increased in patients with severely restricted kidney function, epilepsy and meningitis.
Emergency Measures
In case of overdose, Такс-О-Бид must be discontinued and supportive treatment initiated, which includes measures to accelerate elimination and symptomatic treatment of adverse reactions e.g. convulsions.
Drug initiated cramps can be treated with diazepam or phenobarbital, but not with phenytoin. With anaphylactic reactions the usual emergency measures must be commenced, preferably with the first indications.
No specific antidote exists. Plasma levels of Такс-О-Бид can be reduced by haemodialysis or peritoneal dialysis
ATC Classification
Pharmacotherapeutic group: Beta-lactam antibiotics, cephalosporins.
ATC Code: J01D D01
Mode of action
Такс-О-Бид exerts its action by binding to one or more of the penicillin-binding proteins (PBPs) which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thereby inhibiting cell wall synthesis.
Mechanisms of resistance
Resistance to Такс-О-Бид may be due to one or several of the following mechanisms:
- production of extended-spectrum beta-lactamases (ESBLs)
- induction and/or constitutive expression of AmpC beta- lactamases
- reduced outer membrane permeability
- efflux pump mechanisms.
- Modification of target enzymes (altered PBPs)
More than one of these mechanisms may co-exist in a single bacterium.
PK/PD relationship
Efficacy mainly depends on time above the minimal inhibitory concentration of Такс-О-Бид for the pathogen(s) to be treated (T/MIC).
Breakpoints:
Current MIC breakpoints used to interpret Такс-О-Бид susceptibility data are shown below.
European Committee on Antimicrobial Susceptibility Testing (EUCAST) Clinical MIC Breakpoints (V1.1, 31/03/2006)
| Susceptible (< )/ Resistant (> ) | |
| Enterobacteriaceae2 | 1/2 |
| Pseudomonas | -- |
| Acinetobacter | -- |
| Staphylococcus 3 | Note3 |
| Enterococcus | -- |
| Streptococcus A, B, C, G | 0.5/0.54 |
| Streptococcus pneumoniae | 0.5/24 |
| Haemophilus influenzae Moraxella Catarrhalis | 0.12/0.124 |
| Neisseria gonorrhoea | 0.12/0.124 |
| Neisseria Meningitidis | 0.12/0.124 |
| Gram-negative, anaerobes | -- |
| Non-species related breakpoints1 S≤ />R | 1/2 |
1. Non-species related breakpoints have been determined mainly on the basis of PK/PD data and are independent of MIC distributions of specific species. They are for use only for species that have not been given a species-specific breakpoint and not for those species where susceptibility testing is not recommended (marked with -- or IE in the table).
2. The cephalosporin breakpoints for Enterobacteriaceae will detect resistance mediated by most ESBLs and other clinically important beta-lactamases in Enterobacteriaceae. However, some ESBL-producing strains may appear susceptible or intermediate with these breakpoints. Laboratories may want to use a test which specifically screens for the presence of ESBL.
3. Susceptibility of staphylococci to cephalosporins is inferred from the methicillin susceptibility (except ceftazidime which should not be used for staphylococcal infections).
4. Strains with MIC values above the S/I breakpoint are very rare or not yet reported. The identification and antimicrobial susceptibility tests on any such isolate must be repeated and if the result is confirmed the isolate sent to a reference laboratory. Until there is evidence regarding clinical response for confirmed isolates with MIC above the current resistant breakpoint (in italics) they should be reported resistant.
-- = Susceptibility testing not recommended as the species is a poor target for therapy with the drug.
IE = There is insufficient evidence that the species in question is a good target for therapy with the drug.
RD = rationale document listing data used by EUCAST for determining breakpoints.

^Methicillin-(oxacillin) resistant staphylococci (MRSA) are always resistant to Такс-О-Бид.
Penicillin-resistant Streptococcus pneumoniae show a variable degree of resistance to cephalosporins such as Такс-О-Бид.
After a 1000 mg intravenous bolus, mean peak plasma concentrations of Такс-О-Бид usually range between 81 and 102 microgram/ml. Doses of 500 mg and 2000 mg produce plasma concentrations of 38 and 200 microgram /ml, respectively. There is no accumulation following administration of 1000 mg intravenously or 500 mg intramuscularly for 10 or 14 days.
The apparent volume of distribution at steady-state of Такс-О-Бид is 21.6 litres/1.73 m2 after 1 g intravenous 30 minute infusion.
Concentrations of Такс-О-Бид (usually determined by non-selective assay) have been studied in a wide range of human body tissues and fluids. Cerebrospinal fluid concentrations are low when the meninges are not inflamed, but are between 3 and 30 microgram/ml in children with meningitis. Такс-О-Бид usually passes the blood-brain barrier at levels above the MIC of common sensitive pathogens when the meninges are inflamed. Concentrations (0.2-5.4 microgram/ml), inhibitory for most Gram-negative bacteria, are attained in purulent sputum, bronchial secretions and pleural fluid after doses of 1 or 2 g. Concentrations likely to be effective against most sensitive organisms are similarly attained in female reproductive organs, otitis media effusions, prostatic tissue, interstitial fluid, renal tissue, peritoneal fluid and gall bladder wall, after usual therapeutic doses. High concentrations of Такс-О-Бид and desacetyl-Такс-О-Бид are attained in bile.
Такс-О-Бид is partially metabolised prior to excretion. The principal metabolite is the microbiologically active product, desacetyl-Такс-О-Бид. Most of a dose of Такс-О-Бид is excreted in the urine about 60% as unchanged drug and a further 24% as desacetyl-Такс-О-Бид. Plasma clearance is reported to be between 260 and 390 ml/minute and renal clearance 145 to 217 ml/minute.
After intravenous administration of Такс-О-Бид to healthy adults, the elimination half-life of the parent compound is 0.9 to 1.14 hours and that of the desacetyl metabolite, about 1.3 hours.
In neonates the pharmacokinetics are influenced by gestational and chronological age, the half-life being prolonged in premature and low birth weight neonates of the same age.
In severe renal dysfunction the elimination half-life of Такс-О-Бид itself is increased minimally to about 2.5 hours, whereas that of desacetyl-Такс-О-Бид is increased to about 10 hours. Total urinary recovery of Такс-О-Бид and its principal metabolite decreases with reduction in renal function.
