What is Corus 1020?
Corus 1020 inhalation is an antibiotic that is used to treat lung infections in patients with cystic fibrosis. The medicine is breathed into the lungs through the mouth to treat infections caused by the Pseudomonas aeruginosa bacteria.
Corus 1020 works by killing bacteria or preventing their growth. However, Corus 1020 will not work for colds, flu, or other virus infections.
Corus 1020 is available only with your doctor's prescription.
Corus 1020 indications
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Corus 1020 (Corus 1020 for injection, USP) and other antibacterial drugs, Corus 1020 should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
Corus 1020 is indicated for the treatment of the following infections caused by susceptible Gram-negative microorganisms:
Urinary Tract Infections (complicated and uncomplicated), including pyelonephritis and cystitis (initial and recurrent) caused by Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Enterobacter cloacae, Klebsiella oxytoca*, Citrobacter species*, and Serratia marcescens*.
Lower Respiratory Tract Infections, including pneumonia and bronchitis caused by Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Haemophilus influenzae, Proteus mirabilis, Enterobacter species, and Serratia marcescens*.
Septicemia caused by Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis*, Serratia marcescens*, and Enterobacter species.
Skin and Skin-Structure Infections, including those associated with postoperative wounds, ulcers, and burns, caused by Escherichia coli, Proteus mirabilis, Serratia marcescens, Enterobacter species, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Citrobacter species*.
Intra-abdominal Infections, including peritonitis caused by Escherichia coli, Klebsiella species including K. pneumoniae, Enterobacter species including E. cloacae*, Pseudomonas aeruginosa, Citrobacter species* including C. freundii*, and Serratia species* including S. marcescens*.
Gynecologic Infections, including endometritis and pelvic cellulitis caused by Escherichia coli, Klebsiella pneumoniae*, Enterobacter species* including E. cloacae*, and Proteus mirabilis*.
Corus 1020 is indicated for adjunctive therapy to surgery in the management of infections caused by susceptible organisms, including abscesses, infections complicating hollow viscus perforations, cutaneous infections, and infections of serous surfaces. Corus 1020 is effective against most of the commonly encountered Gram-negative aerobic pathogens seen in general surgery.
————————————
* Efficacy for this organism in this organ system was studied in fewer than 10 infections.
Concurrent Therapy
Concurrent initial therapy with other antimicrobial agents and Corus 1020 is recommended before the causative organism(s) is known in seriously ill patients who are also at risk of having an infection due to Gram-positive aerobic pathogens. If anaerobic organisms are also suspected as etiologic agents, therapy should be initiated using an anti-anaerobic agent concurrently with Corus 1020. Certain antibiotics (eg, cefoxitin, imipenem) may induce high levels of beta-lactamase in vitro in some Gram-negative aerobes such as Enterobacter and Pseudomonas species, resulting in antagonism to many beta-lactam antibiotics including Corus 1020. These in vitro findings suggest that such beta-lactamase-inducing antibiotics not be used concurrently with Corus 1020. Following identification and susceptibility testing of the causative organism(s), appropriate antibiotic therapy should be continued.

Corus 1020 dosage
Corus 1020 Dosage
Generic name: Corus 1020 1g
Dosage form: injection, powder, for solution
The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.
Dosage in Adult Patients
Corus 1020 may be administered intravenously or by intramuscular injection. Dosage and route of administration should be determined by susceptibility of the causative organisms, severity and site of infection, and the condition of the patient.
Type of Infection | Dose | Frequency (hours) |
---|---|---|
* Maximum recommended dose is 8 g per day. | ||
Urinary tract infections | 500 mg or 1 g | 8 or 12 |
Moderately severe systemic infections | 1 g or 2 g | 8 or 12 |
Severe systemic or life-threatening infections | 2 g | 6 or 8 |
Because of the serious nature of infections due to Pseudomonas aeruginosa, dosage of 2 g every six or eight hours is recommended, at least upon initiation of therapy, in systemic infections caused by this organism.
The intravenous route is recommended for patients requiring single doses greater than 1 g or those with bacterial septicemia, localized parenchymal abscess (eg, intra-abdominal abscess), peritonitis, or other severe systemic or life-threatening infections.
The duration of therapy depends on the severity of infection. Generally, Corus 1020 should be continued for at least 48 hours after the patient becomes asymptomatic or evidence of bacterial eradication has been obtained. Persistent infections may require treatment for several weeks. Doses smaller than those indicated should not be used.
Renal Impairment in Adult Patients
Prolonged serum levels of Corus 1020 may occur in patients with transient or persistent renal insufficiency. Therefore, the dosage of Corus 1020 should be halved in patients with estimated creatinine clearances between 10 and 30 mL/min/1.73 m2 after an initial loading dose of 1 or 2 g.
When only the serum creatinine concentration is available, the following formula (based on sex, weight, and age of the patient) may be used to approximate the creatinine clearance (Clcr). The serum creatinine should represent a steady state of renal function.
weight (kg) × (140−age)
Males: Clcr = ———————————————
72 × serum creatinine (mg/dL)
Females: 0.85 × above value
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 of 500 mg, 1 g, or 2 g should be given initially. The maintenance dose should be one-fourth of the usual initial dose given at the usual fixed interval of 6, 8, or 12 hours. For serious or life-threatening infections, in addition to the maintenance doses, one-eighth of the initial dose should be given after each hemodialysis session.
Dosage in the 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 be obtained and appropriate dosage modifications made if necessary.
Dosage in Pediatric Patients
Corus 1020 should be administered intravenously to pediatric patients with normal renal function. There are insufficient data regarding intramuscular administration to pediatric patients or dosing in pediatric patients with renal impairment.
Type of Infection | Dose | Frequency (hours) |
---|---|---|
* Maximum recommended dose is 120 mg/kg/day. | ||
Mild to moderate infections | 30 mg/kg | 8 |
Moderate to severe infections | 30 mg/kg | 6 or 8 |
CLINICAL STUDIES
A total of 612 pediatric patients aged 1 month to 12 years were enrolled in uncontrolled clinical trials of Corus 1020 in the treatment of serious Gram-negative infections, including urinary tract, lower respiratory tract, skin and skin-structure, and intra-abdominal infections.
Preparation of
Parenteral Solutions
General
Upon the addition of the diluent to the container, contents should be shaken immediately and vigorously. Constituted solutions are not for multiple-dose use; should the entire volume in the container not be used for a single dose, the unused solution must be discarded.
Depending upon the concentration of Corus 1020 and diluent used, constituted Corus 1020 yields a colorless to light straw yellow solution which may develop a slight pink tint on standing (potency is not affected).
Parenteral drug products should be inspected visually for particulate matter and discoloration whenever solution and container permit.
Admixtures with Other Antibiotics
Intravenous infusion solutions of Corus 1020 not exceeding 2% w/v prepared with Sodium Chloride Injection, USP 0.9% or Dextrose Injection, USP 5%, to which clindamycin phosphate, gentamicin sulfate, tobramycin sulfate, or cefazolin sodium have been added at concentrations usually used clinically, are stable for up to 48 hours at room temperature or 7 days under refrigeration. Ampicillin sodium admixtures with Corus 1020 in Sodium Chloride Injection, USP 0.9% are stable for 24 hours at room temperature and 48 hours under refrigeration; stability in Dextrose Injection, USP 5% is 2 hours at room temperature and 8 hours under refrigeration.
Corus 1020-cloxacillin sodium and Corus 1020-vancomycin hydrochloride admixtures are stable in Dianeal 137 (Peritoneal Dialysis Solution) with 4.25% Dextrose for up to 24 hours at room temperature.

Corus 1020 solutions at concentrations exceeding 2% w/v, except those prepared with Sterile Water for Injection, USP or Sodium Chloride Injection, USP, should be used promptly after preparation; the 2 excepted solutions must be used within 48 hours if stored at controlled room temperature or within 7 days if refrigerated.
Intravenous Administration
Bolus Injection: A bolus injection may be used to initiate therapy. The dose should be slowly injected directly into a vein, or the tubing of a suitable administration set, over a period of 3 to 5 minutes.
Infusion: With any intermittent infusion of Corus 1020 and another drug with which it is not pharmaceutically compatible, the common delivery tube should be flushed before and after delivery of Corus 1020 with any appropriate infusion solution compatible with both drug solutions; the drugs should not be delivered simultaneously. Any Corus 1020 infusion should be completed within a 20- to 60-minute period. With use of a Y-type administration set, careful attention should be given to the calculated volume of Corus 1020 solution required so that the entire dose will be infused. A volume control administration set may be used to deliver an initial dilution of Corus 1020 into a compatible infusion solution during administration; in this case, the final dilution of Corus 1020 should provide a concentration not exceeding 2% w/v.
Intramuscular Administration
The dose should be given by deep injection into a large muscle mass (such as the upper outer quadrant of the gluteus maximus or lateral part of the thigh). Corus 1020 is well tolerated and should not be admixed with any local anesthetic agent.
