Aztreo: Introduction
Aztreo is an antibiotic that belongs to the monobactam class of medications. It is used to treat infections caused by certain bacteria including Pseudomonas aeruginosa, Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, and other susceptible organisms. It was the first monobactam antibiotic available on the market and is only used to treat gram-negative bacterial infections.Uses
Aztreo is used to treat infections caused by certain bacteria, including, but not limited to, urinary tract infections, respiratory tract infections, female genital tract infections, intraabdominal infections, and skin and soft tissue infections. It is also used to treat some Pseudomonas-related infections, including pneumonia and infections of burns, skin, and ulcers.Mechanism of Action
Aztreo works by inhibiting the plasmid-mediated production of β-lactamase, a key enzyme used in the production of cell wall components of bacterial cells. This prevents bacteria from fully forming its cell wall, weakening and destroying it. It is effective only against gram-negative bacteria and is not active against gram-positive and anaerobic bacteria.How Long Does It Take to Work?
Aztreo begins to work quickly and is generally effective within 24 hours. However, it may take up to 48 hours to be completely effective and start reducing symptoms of infection.Absorption
Aztreo is not well absorbed when taken orally and is usually only taken intravenously. Studies have shown that it has a bioavailability of 20-37% when administered as an intravenous injection.Route of Elimination
Aztreo is eliminated by the kidneys. It is principally eliminated by glomerular filtration and tubular secretion. Its elimination half-life ranges from 1.6 to 3.6 hours, but may be prolonged during impaired renal function.Dosage
Aztreo is available in 1-2 g vials and is usually administered by slow intravenous injection as a single dose therapy or as multiple doses, depending on the infection being treated. For infections caused by Pseudomonas aeruginosa, a single dose of 2 g administered internally every 8 to 12 hours is recommended. For infections caused by Escherichia coli a single-dose of 1-2 g administered internally every 12 hours is typically sufficient. It is important to follow your doctor’s instructions for the route, dosage, and frequency of administration for the best results and to avoid any potential side effects or complications.Administration
Aztreo should only be administered intravenously. It should be injected slowly over approximately three to five minutes and must not be mixed with any other solution. It should be used with caution in patients with renal impairment and the dosage should be adjusted in patients with severe renal impairment.Side Effects
Aztreo is generally considered to be well-tolerated, however, it can cause some side effects such as nausea, vomiting, diarrhea, abdominal pain, rash, and itching. It can also cause more serious side effects such as kidney damage, changes in urine color, and increased levels of liver enzymes.Toxicity
Aztreo is generally well-tolerated at the prescribed dose. However, it can be toxic in high concentrations, leading to the symptoms of anaphylaxis. Overdose of aztreonam should be considered if there are signs of an adverse drug reaction.Precautions
Aztreo should be used with caution in pregnant or breastfeeding women, patients with severe renal impairment, and those with a history of hypersensitivity reactions to β-lactam antibiotics.Interactions
Aztreo may interact with other drugs, such as other antibiotics, antifungal medications, antiviral medications, and diuretics. It is important to tell your doctor if you are taking any other medications before taking aztreonam.Disease Interaction
Aztreo may interact with certain diseases and medical conditions, such as kidney disorders, abnormal liver enzymes, diabetes, and impaired immune system. Aztreo should not be used in patients with a history of hypersensitivity reactions to β-lactam antibiotics.Drug Interactions
Aztreo may interact with other drugs. It has been shown to have an increased risk of adverse reactions when combined with warfarin, ciclosporin, and diuretics. Combining aztreonam with non-steroidal anti-inflammatory drugs (NSAIDs) may also increase the risk of certain adverse effects.Food Interactions
Aztreo should not be taken with alcohol or grapefruit juice as it can increase the risk of side effects. It should also be avoided if taking antacids, as these can interfere with the absorption of the medication.Pregnancy Use
Aztreo should be used with caution in pregnant or breastfeeding women. Animal studies have not shown any evidence of teratogenic effects with aztreonam but there is currently limited data on the use of aztreonam in pregnancy. It is recommended to consult your doctor before taking this medication if you are pregnant or breastfeeding.Lactation Use
Aztreo is excreted in breast milk in small amounts. It is recommended to consult your doctor before taking this medication if you are breastfeeding.Acute Overdose
An acute overdose of aztreonam is rare but may cause symptoms of anaphylaxis such as rash, hives, difficulty breathing, and throat tightness. Seek immediate medical attention if these symptoms occur.Contraindication
Aztreo should not be used in patients with a history of hypersensitivity reactions to β-lactam antibiotics. It should also not be used in patients with a history of anaphylaxis to penicillin, or to other β-lactams.Directions for Use
Aztreo should only be administered intravenously. It should be injected slowly over approximately three to five minutes and must not be mixed with any other solution. The dosage and frequency of administration should be adjusted in patients with severe renal impairment.Storage Conditions
Aztreo should be stored at room temperature (between 15-30°C). It must not be frozen or exposed to direct sunlight. It should be protected from moisture and any solution should not be stored for more than 24 hours at a temperature below 25°C.Volume of Distribution
The volume of distribution of aztreonam is approximately 0.2 L/kg. It is primarily distributed into the extracellular fluid and is not highly bound to plasma proteins.Half Life
The half-life of aztreonam in healthy adult males is approximately 1.6 to 3.6 hours. However, this may be prolonged in patients with severe renal impairment.Clearance
The clearance of aztreonam is approximately 9mL/min/kg in healthy adult males. However, this can be reduced in patients with renal impairment.Here you find in details version of Aztreo
