1. What Azactam is and what it is used for
The name of this medicine is Azactam. The active ingredient in Azactam is aztreonam.
Azactam is available in two strengths and each vial contains either 1g or 2g aztreonam as a powder for solution
for injection or infusion. Aztreonam is an antibiotic and a member of the family of medicines called monobactams.
Azactam also contains L-arginine.
Azactam is for the treatment of serious infections caused by bacteria which require an antibiotic injection.

Always tell your doctor or pharmacist about other medicines you may be taking or have recently taken including those
obtained without a prescription. Some medicines can have an effect on each others actions.
If you are pregnant or may become pregnant or are breast feeding, you should speak to your doctor before being treated
with Azactam.

The dose range of Azactam is 1 to 8g daily in equally divided doses. The usual
dose is 3 to 4g daily. The maximum recommended dose is 8g daily. The dosage
and route of administration should be determined by the susceptibility of the
causative organisms, severity of infection, and the condition of the patient.

Because of the serious nature of infections due to Pseudomonas
aeruginosa, a dose of 2g every 6 or 8 hours is recommended, at least for
initial therapy in systemic infections caused by this organism.
The intravenous route is recommended for patients requiring single doses
greater than 1g, or those with bacterial septicaemia, localised parenchymal
abscess (e.g. intra-abdominal abscess), peritonitis, meningitis or other severe
systemic or life-threatening infections.
Paediatric: The usual dose for patients older than one week is 30mg/kg/dose
every 6 or 8 hours. For severe infections in patients 2 years of age or older,
50mg/kg/dose every 6 or 8 hours is recommended. The recommended dose
for all patients in the treatment of infections due to P. aeruginosa is 50 mg/kg
every six to eight hours. The maximum daily paediatric dose should not exceed
the maximum recommended dose for adults. Dosage information is not yet
available for new-borns less than 1 week old.
Elderly: Renal status is a major determinant of dosage in the elderly; these
patients in particular may have diminished renal function. Serum creatinine
may not be an accurate determinant of renal status. Therefore, as with all
antibiotics eliminated by the kidneys, estimates of creatinine clearance should


Elderly patients normally have a creatinine clearance in excess of 30mL/min
and therefore would receive the normal recommended dose. If renal function is
below this level, the dosage schedule should be adjusted (see Renal Impairment).
Renal Impairment: Prolonged serum levels of aztreonam may occur in
initial usual dose, the dosage of aztreonam should be halved in patients with
estimated creatinine clearances between 10 and 30 mL/min/1.73 m2.
In patients with severe renal failure (creatinine clearance less than
10 mL/min/1.73 m2), such as those supported by hemodialysis, the usual dose
should be given initially. The maintenance dose should be one-fourth of the

or life-threatening infections, in addition to the maintenance doses, one-eighth
of the initial dose should be given after each hemodialysis session.

one to four doses a day. Maximum recommended dose is 8 g per day.
The usual daily dose in children older than one week is 30mg per kg of body weight given every 6 to 8 hours, but in
severe infections in patients two years of age or older this will be increased to 50mg per kg of body weight.
If you are given more Azactam than you should
It is unlikely that you will receive more Azactam than you should as it will be administered by injection into a muscle or
vein by a doctor, nurse or other suitably trained person. If this does happen you will be closely monitored.
As with all medicines, Azactam can cause unwanted side effects, although not everybody gets them.

Hepatic impairment:
A dose reduction of 20-25% is recommended for long-term treatment of
patients with chronic liver disease with cirrhosis, especially in cases of
alcoholic cirrhosis and when renal function is also impaired.
Azactam Powder for Solution for Injection or Infusion is supplied in 15mL vials.
Upon the addition of the diluent the contents should be shaken immediately and
vigorously. Vials of reconstituted Azactam are not intended for multi-dose use,
and any unused solution from a single dose must be discarded. Depending on
the type and amount of diluent, the pH ranges from 4.5 to 7.5, and the colour
may vary from colourless to light straw-yellow, which may develop a slight
pink tint on standing; however this does not affect the potency.
For intramuscular injections: For each gram of aztreonam add at least 3mL
Water for Injections Ph Eur or 0.9% Sodium Chloride BP and shake well.
Single-Dose Vial Size
Volume of Diluent to be added
Azactam is given by deep injection into a large muscle mass, such as the upper
outer quadrant of the gluteus maximus or the lateral part of the thigh.
For intravenous injection: To the contents of the vial add 6 to 10mL of Water
for Injections Ph Eur, and shake well. Slowly inject directly into the vein over
a period of 3 to 5 minutes.
For intravenous infusion: For each gram of aztreonam, add at least 3mL of
Water for Injections Ph Eur and shake well. Dilute this initial solution with an
50mL solution per gram of aztreonam). The infusion should be administered
over 20-60 minutes.
Appropriate infusion solutions include: 0.9% Sodium Chloride Injection
BP 5% Glucose Intravenous Infusion BP, 5% or 10% Mannitol Intravenous
Infusion BP, Sodium Lactate Intravenous Infusion BP, 0.9%, 0.45% or
0.2% Sodium Chloride & 5% Glucose I.V. Infusion BP, Compound Sodium
Chloride Injection BPC 1959 (Ringer’s Solution for Injection), Compound
Sodium Lactate Intravenous Infusion BP (Hartmann’s Solution for Injection).
A volume control administration set may be used to deliver the initial solution
of Azactam into a compatible infusion solution being administered. With use of
a Y-tube administration set, careful attention should be given to the calculated
volume of Azactam solution required so that the entire dose will be infused.
With intermittent infusion of Azactam and another drug via a common delivery
appropriate infusion solution compatible with both drug solutions. Except for the
antibiotics described below, the drugs should not be delivered simultaneously.
Reconstitution: Intravenous infusion solution of Azactam for Injection
prepared with 0.9% Sodium Chloride Injection BP or 5% Glucose Intravenous
Infusion BP, in PVC or glass containers, to which clindamycin phosphate,
gentamicin sulphate, tobramycin sulphate, or cephazolin sodium have been
added at concentrations usually used clinically, are stable for up to 24 hours
in a refrigerator (2-8°C). Ampicillin sodium admixtures with aztreonam in
0.9% sodium chloride injection BP are stable for 24 hours in a refrigerator
(2-8°C); stability in 5% Glucose Intravenous Infusion BP is eight hours under
refrigeration. Store the reconstituted solution at 2°C-8°C (under refrigeration)
for not more than 24 hours. Discard any unused solution.
If aztreonam and metronidazole are to be used together, they should be
administered separately as a cherry red colour has been observed after storage
of solutions containing combinations of the two products.
Any unused medicinal product or waste material should be disposed of in
accordance with local requirements.
