2. Qualitative and quantitative composition

1 vial contains 1.11 g temocillin disodium, corresponding to 1 g temocillin.

For the full list of excipients, see section 6.1.

3. Pharmaceutical form

Powder for solution for injection/infusion.

Vial containing a white to pale yellow sterile solid.

4. Clinical particulars
4.1 Therapeutic indications

Negaban is indicated for the treatment of septicaemia, urinary tract infection and lower respiratory tract infection where susceptible gram-negative bacilli are suspected or confirmed.

In mixed infections where gram-positive or anaerobic bacteria are also liable to be implicated, co-administration with other appropriate antibacterial agents should be considered.

Consideration should be given to official guidance on the appropriate use of antibacterial agents.

4.2 Posology and method of administration


Patients with normal renal function

Adults (including the elderly):

Usual dose: 4 g per day to be divided into 2 administrations or as continuous infusion.

High dose notably in critically ill patients: 6 g per day to be divided into 3 administrations or as continuous infusion.

A loading dose of 2 g should be administered before starting the continuous infusion (see Method of administration).

Children: Insufficient data are available to recommend an appropriate dosage regimen.

Patients with renal insufficiency

Adults (including the elderly):

Temocillin is mainly excreted renally and unchanged. Excretion is reduced in renal impairment and half-life is increased according to the severity of renal failure. In moderate and severe renal failure, dose adjustments are necessary in accordance with the following regimen:

Creatinine clearance (ml/min)

In case of intermittent high-flux hemodialysis:

As a rule, the I.M. route should be avoided, considering the patient's treatment with heparin. I.V. injection of Negaban is recommended, using water for injection or physiological saline as solvent: 1 g (I.V. injection) per 24 h of inter-dialytic session, preferably at the end of the hemodialysis (1 g q24 h, 2 g q48 h, 3 g q72 h).

In case of continuous peritoneal dialysis in ambulatory patients:

1 g Negaban I.M. every 24 hours.

These data are based on studies where creatinine clearance was used to estimate the degree of renal impairment.

Patients with impaired liver function

Limited experience in patients with impaired hepatic function has not indicated a need for a reduction in dosage.

Method of administration

Negaban may be administered by intravenous injection, intermittent or continuous intravenous infusion, or intramuscular injection.

Intravenous solutions: Negaban solutions should be administered by slow injection into the vein (3-4 minutes) or as an intravenous infusion over a period of 30-40 minutes. Continuous intravenous infusion of temocillin might be considered when therapeutic objectives are difficult to reach with intermittent administrations. A loading dose of 2 g should be administered before starting the continuous infusion.

Intramuscular injection: Negaban may be given intramuscularly after reconstitution. If pain is experienced at the site of I.M. injection, a sterile solution of lidocaine hydrochloride 0.5-1% may be used in place of water for injection.

For instructions on reconstitution of the medicinal product before administration, see section 6.6.

4.3 Contraindications

The use of Negaban is contraindicated in patients with a history of allergic reactions to any of the penicillins or any other type of beta-lactam drug.

4.4 Special warnings and precautions for use

Serious and occasionally fatal anaphylactic reactions have been reported in patients receiving therapy with penicillins. If an allergic reaction occurs during therapy with Negaban, the drug must be discontinued.

Cross-allergy with cephalosporins is frequent (10 to 15%).

In patients with kidney failure, the posology must be adapted to the degree of insufficiency, as recommended in Section 4.2. Posology and Method of Administration.

Bleeding manifestations have occurred in some patients receiving beta-lactam antibiotics. These reactions have sometimes been assessed with abnormalities of coagulation tests and are more likely to occur in patients with renal failure.

If bleeding manifestations occur, the antibiotic should be discontinued and appropriate therapy instituted.

As with any antibiotic, temocillin may be associated with induced pseudomembranous colitis, although animal studies have never shown any induction of Clostridium difficile infection. In case of severe, persistent diarrhoea, caution is recommended, Negaban must be discontinued and suitable therapy be initiated (eg oral metronidazole or oral vancomycin). Preparations which inhibit peristalsis are contra-indicated.

As with other antibiotics, the possibility of emergence of resistant organisms which might cause superinfections should be kept in mind, particularly during prolonged treatment. Microbiological follow-up may be required to detect any important superinfection. If this occurs, appropriate measures should be taken.

As with other penicillins, patients may experience neuromuscular excitability or convulsions if higher than recommended doses are given intravenously.

Periodic electrolyte determinations should be made in patients with low potassium reserves and the possibility of hypokalaemia should be kept in mind with patients who have potentially low potassium reserves and who are receiving cytotoxic therapy or diuretics. Modest elevations of indices of liver function may be observed.

Sodium content: approximately 5 mmol per vial.

4.5 Interaction with other medicinal products and other forms of interaction

None known.

4.6 Fertility, pregnancy and lactation


Animal studies with temocillin have shown no teratogenic effects. There is no experience of temocillin in human pregnancy. Therefore, its use in pregnancy cannot be recommended.


Trace quantities of penicillins can be detected in the milk of lactating mothers. Therefore, mothers should not breastfeed their infants while receiving temocillin.


In animal studies, no effects on fertility have been observed with temocillin (see Section 5.3).

4.7 Effects on ability to drive and use machines

None known.

4.8 Undesirable effects

Undesirable effects are typical of the injectable penicillins: they may include diarrhoea, pain at the site of I.M. injection, occasionally rash, either urticarial or erythematous.

Certain reactions such as fever, arthralgia or myalgia, sometimes develop more than 48 hours after the start of the treatment. In any case, discontinuance of treatment and recourse to another appropriate antibiotic therapy are essential.

In common with other ß-lactam antibiotics angioedema and anaphylaxis have been reported.

There is also a risk of phlebitis and thrombophlebitis with intravenous administration of ß-lactam antibiotics, although to a lesser extent in the case of Negaban.

In patients suffering from renal failure, neurological disorders with convulsions have been reported following the I.V. injection of high doses of penicillin.

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 on the website

4.9 Overdose

There have been no reported cases of overdosage. Dosages of up to 8 g daily have been administered to volunteers without untoward effects.

Negaban may be removed from the circulation by haemodialysis.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: ß-lactam antibacterials - penicillins (ATC code: J01CA17)

The product is an injectable antibiotic active in vitro against many aerobic gram-negative bacteria, with the notable exception of Pseudomonas aeruginosa and Acinetobacter spp.

Mechanism of action:

ß-lactam antibiotics act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls. ß-lactam antibiotics irreversibly bind to the active site of specific transpeptidases and carboxypeptidases known as Penicillin Binding Proteins (PBP), preventing peptidoglycan production.

Mechanism of resistance:

Temocillin is stable to most types of ß-lactamases, including most AmpC and Extended Spectrum ß-Lactamases. The only suspected mechanisms of resistance to temocillin are outer membrane impermeabilisation or active efflux.

ß-lactamase-producing Enterobacteriaceae resistant to 2nd or 3rd generation cephalosporins may be sensitive to Negaban.

Distribution: The protein serum binding rate is 85% in healthy volunteers.

Concentrations of temocillin in gall bladder bile at a mean of 2.4 hours after I.V. injection of 1 g were variable. Temocillin was not detected in the bile of 2 out of 10 patients but in some cases concentrations were considerably higher than those in serum. The mean concentration in gall bladder bile was 205 μg/ml. Concentrations of temocillin in prostate homogenate between 1 and 3 hours after I.M. injection of 1 g of temocillin ranged from 2.3-16 μg/ml (mean 8.25) compared with a mean serum concentration of 12.5 μg/ml.

In a series of studies, the penetration of temocillin into tissues was investigated by assaying either tissue fluid or homogenate for temocillin. Following I.V. injection of 1 g of temocillin, concentrations in the fluid of cantharidine-induced skin blisters reached a mean peak of 44.3 μg/ml at 3 hours. The mean half-life of temocillin in blister fluid was 4.0 hours.

Temocillin concentrations in peripheral lymph after a 1 g I.V. injection were of a similar order to those in blister fluid, reaching a mean peak of 30.6 μg/ml between 1.5 and 2 hours. The mean half-life of elimination from lymph was 4.4 hours. As was found in skin blisters, concentrations of temocillin in lymph were above the MIC of susceptible bacteria at 12 hours after administration.

Only a small proportion of temocillin passes into the cerebrospinal fluid.

Excretion: Temocillin is excreted unchanged mainly in the kidney. Excretion may be delayed in cases of kidney failure so the dosage must be reduced, depending on the degree of kidney failure shown by the creatinine clearance values.

5.3 Preclinical safety data

The non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, single and repeated dose toxicity, mutagenic toxicity and toxicity to reproduction and development. Fertility studies performed in rats administered temocillin subcutaneously showed no adverse effects on male and female fertility at 0.18 times the exposure levels achieved for the maximum recommended human intravenous daily dose.
