Azactam is usually given in a healthcare setting by intravenous (IV) injection or intramuscular (IM) injection. The route of administration depends on the severity of the infection, the patient’s condition, and the physician’s judgment.

Intravenous (IV) Injection:

For adults, the average dose of aztreonam for most infections is 1 to 2 grams given every 6 to 8 hours depending on the severity of the infection. The maximum dose for adults is 8 grams per day.

The drug is usually given over 30 minutes to 1 hour via an intravenous infusion.

High dosages are administered under medical guidance in severe infections or resistant organism infections.

 Intramuscular (IM) Injection:

Aztreonam can be administered via intramuscular injection for adults, typically 1 to 2 grams every 8 to 12 hours as needed based on the patient’s condition. Pediatric Use:

For pediatric patients, the dosing of aztreonam is based on the child’s weight as well as the type of infection being treated. This dosage is divided into a few doses that range between 30 mg/kg and 100 mg/kg per day.

It acts by inhibiting the synthesis of bacterial cell wall. More precisely, it binds to PBPs located in the bacterial cell wall, interfering with the final steps of peptidoglycan synthesis.

 Peptidoglycan is an essential component of the bacterial cell wall, which gives structural integrity to the organism. By inhibiting this synthesis, aztreonam causes the bacterial cell wall to weaken and eventually leads to cell lysis and death of the bacteria.

Azactam is most active against aerobic gram-negative bacteria, which have a unique outer membrane that protects them from certain antibiotics. Azactam can penetrate the outer membrane and bind to PBPs, effectively killing the bacteria.

Like all other medications, Azactam can also cause side effects. The side effects can range from mild to serious, depending on the nature of side effects. Some common side effects are listed below.

• Pain or redness at the injection site (for IM or IV administration)
• Rash or allergic reaction: This may include skin rash, itching, or swelling, especially if the patient is allergic to the drug.

Gastrointestinal: Nausea, vomiting, diarrhea, or abdominal pain.

Elevated liver enzymes: Azactam may cause a change in liver function, and patients may have an elevated level of liver enzymes.

Fever: Some patients may develop a mild fever.

Headache: A mild to moderate headache may occur in some patients.

Serious side effects, though rare, can include:

Severe allergic reactions (anaphylaxis): This is a rare but serious side effect, characterized by symptoms like difficulty breathing, swelling of the face or throat, and a rapid heartbeat. Immediate medical attention is necessary.

Clostridium difficile-associated diarrhea: This is a risk with almost all antibiotics and can cause severe, life-threatening diarrhea.

Severe skin reactions: Symptoms such as blistering, peeling skin, or severe rashes may require discontinuation of the drug.

Allergic Reactions: Azactam is to be used with caution in patients with a known allergy to beta-lactam antibiotics (penicillins, cephalosporins). The risk of cross-reactivity is low, but allergic reactions can still occur.

Renal Impairment: Dosage adjustment may be necessary in patients with renal impairment. Azactam is excreted mainly by the kidneys, so impaired renal function can result in increased drug levels and toxicity.

Liver Dysfunction: Azactam may cause impairment of liver function, and liver function tests should be monitored during treatment, especially in patients with pre-existing liver disease.

Superinfection: As with other broad-spectrum antibiotics, aztreonam may result in an overgrowth of resistant organisms, including Candida (yeast) or Clostridium difficile. Prolonged use should be monitored more closely for signs of superinfection.

Pregnancy and Breastfeeding: Azactam should be used during pregnancy only if clearly needed. It is excreted in breast milk, so caution should be exercised when administering the drug to breastfeeding mothers.

1. Aminoglycosides: Co-administration with aminoglycosides (e.g., gentamicin) can increase the risk of nephrotoxicity, so renal function should be monitored closely.
2. Probenecid: Concomitant use may decrease Azactam’s renal elimination, potentially increasing its serum levels and risk of toxicity.
3. Diuretics: Certain diuretics (e.g., furosemide) may also elevate the risk of nephrotoxicity when used with Azactam.
4. Anticoagulants: Azactam may increase the effects of anticoagulants, requiring more frequent monitoring of clotting parameters.

Always consult with a healthcare provider before combining medications.

The dose of Azactam (aztreonam) varies based on the patient’s condition, severity of infection, and response to the drug. For adults, a typical dose is from 1 to 2 grams every 6-8 hours depending on the nature of the infection, while for children, it’s up to 8 grams in a day.

In pediatrics, the typical dosing is between 30 mg/kg/day and 100 mg/kg/day given in divided doses.

Azactam is a prescription drug and must be prescribed by a healthcare professional. It is used in the hospital or clinical setting, especially for more serious infections that require intravenous or intramuscular administration.
