Table 1. Recommended Cosyntropin for Injection Dose for Pediatric Patients Age Recommended Dose Volume of Reconstituted Solution Birth to less than 2 years 0.125 mg 0.5 mL 2 to 17 years 0.25 mg 1 mL
2.4Reconstitution Instructions • Aseptically reconstitute the lyophilized powder in the vial using 1 mL of 0.9% Sodium Chloride Injection, USP and gently swirl. • After reconstitution, the final concentration of cosyntropin for injection reconstituted solution is 0.25 mg/mL. • Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. The reconstituted cosyntropin for injection solution should be clear and colorless, and free of particulates.
If cosyntropin for injection solution is cloudy or contains particulates, do not administer. • If the cosyntropin for injection reconstituted solution is not used immediately, discard the unused cosyntropin for injection reconstituted solution.
2.5Administration Information • Cosyntropin for injection may be administered by intramuscular or intravenous injection. • Obtain blood sample for baseline serum cortisol. Obtain blood samples again for assessment of cortisol levels exactly 30 minutes and 60 minutes after administration of cosyntropin for injection.
2.6Interpretation of Plasma Cortisol Levels after Cosyntropin for Injection • Stimulated plasma cortisol levels of less than 18 mcg/dL at 30- or 60-minutes post cosyntropin for injection are suggestive of adrenocortical insufficiency. Cutoff values for exclusion of adrenocortical insufficiency may vary according to the assay used. Test results can be affected by concomitant medications and certain medical conditions [see Warnings and Precautions ( 5.2 )] .

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Hypersensitivity : reactions including anaphylaxis have been reported. Monitor patients for hypersensitivity reactions and treat as needed. ( 5.1 ) • Diagnostic Inaccuracies : Cortisol levels and subsequent diagnosis of adrenocortical insufficiency following cosyntropin for injection administration may be inaccurate if patients are on certain medications because of their effect on cortisol or cortisol binding globulin levels.
Any condition that elevates or lowers cortisol binding globulin levels may increase or decrease plasma total cortisol levels, respectively. ( 2.1 , 5.2 , 7 )
5.1Hypersensitivity to Cosyntropin for Injection Cosyntropin for injection hypersensitivity reactions including anaphylaxis have been reported. Monitor patients for hypersensitivity reactions and treat as needed.
5.2Diagnostic Inaccuracies Cortisol levels and subsequent diagnosis of adrenocortical insufficiency following cosyntropin for injection administration may be inaccurate if patients are on certain medications because of their effect on cortisol or cortisol binding globulin levels. Glucocorticoids and spironolactone may result in falsely elevated cortisol levels. Stop these drugs on the day of cosyntropin for injection testing.
Long-acting glucocorticoids may need to be stopped for a longer period before cosyntropin for injection testing [see Dosage and Administration ( 2.1 ) and Drug Interactions ( 7 )] . Estrogen-containing drugs increase cortisol binding globulin levels which can increase plasma total cortisol levels. To obtain accurate plasma total cortisol levels, stop estrogen containing drugs four to six weeks before cosyntropin for injection testing to allow cortisol binding globulin levels to return to levels within the reference range [see Dosage and Administration ( 2.1 ) and Drug Interactions ( 7 )] .
Alternatively, concomitant measurement of cortisol binding globulin at the time of testing can be done; if cortisol binding globulin levels are elevated, plasma total cortisol levels are considered inaccurate. Any condition that elevates or lowers cortisol binding globulin levels may increase or decrease plasma total cortisol levels, respectively. Cortisol binding globulin levels can be low in cirrhosis or nephrotic syndrome.
Measure cortisol binding globulin levels as necessary to ensure accuracy of interpretation of plasma total cortisol levels.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Available data from case reports over decades of use with cosyntropin during pregnancy have not identified an increased risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Unidentified adrenal insufficiency can result in adverse maternal or fetal outcomes (see Clinical Considerations) . The background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk for major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk Unidentified adrenal insufficiency during pregnancy can result in maternal and/or fetal death; therefore, the diagnosis of suspected adrenal insufficiency during pregnancy should not be delayed.
8.2Lactation Risk Summary There are no data on the presence of cosyntropin in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for cosyntropin for injection and any potential adverse effects on the breastfed infant from cosyntropin for injection or from the underlying maternal condition.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Cosyntropin exhibits the full corticosteroidogenic activity of natural ACTH. Various studies have shown that the biologic activity of ACTH resides in the N-terminal portion of the molecule and that the 1-20 amino acid residue is the minimal sequence retaining full activity. Partial or complete loss of activity is noted with progressive shortening of the chain beyond 20 amino acid residues.
For example, the decrement from 20 to 19 results in a 70% loss of potency. The pharmacologic profile of cosyntropin is similar to that of purified natural ACTH. It has been established that 0.25 mg of cosyntropin will stimulate the adrenal cortex maximally and to the same extent as 25 units of natural ACTH.
This dose of cosyntropin will produce maximal secretion of 17-OH corticosteroids, 17-ketosteroids and/or 17-ketogenic steroids.
12.2Pharmacodynamics Animal, human and synthetic ACTH (1-39) which all contain 39 amino acids exhibit similar immunologic activity. This activity resides in the C-terminal portion of the molecule and the 22-39 amino acid residues exhibit the greatest degree of antigenicity. In contrast, synthetic polypeptides containing 1-19 or fewer amino acids have no detectable immunologic activity.
Those containing 1-26, 1-24 or 1-23 amino acids have very little immunologic although full biologic activity. This property of cosyntropin assumes added importance in view of the known antigenicity of natural ACTH.
