Pruritus
Chronic pancreatitis
Hypersensitivity
Rash
Peripheral edema
Tachycardia

Postmarketing Reports

Warnings
Contraindications
Hypersensitivity to cosyntropin, synthetic ACTH, or to any excipients
Cautions
Use caution in patients with gastrointestinal disease, cardiovascular disease, hepatic disease, infections, myasthenia gravis, ocular disease, psychiatric disturbances, osteoporosis, renal disease, thyroid disease
Reactions including anaphylaxis are possible; monitor patients for hypersensitivity reactions and treat as needed
Diagnostic inaccuracies
- Accuracy of diagnosis can be complicated by concomitant medications taken by patient; any condition that elevates or lowers cortisol binding globulin levels may increase or decrease plasma total cortisol levels, respectively; for example, cortisol binding globulin levels can be low in cirrhosis or nephrotic syndrome
- Cortisone or hydrocortisone use might falsely elevate or, in a paradoxical response, lower plasma cortisol levels; spironolactone use may result in falsely elevated cortisol levels; patients receiving cortisone, hydrocortisone or spironolactone should omit their pre-test doses on the day selected for testing
- Use of synthetic glucocorticoid preparations (oral, inhaled, or injectable) might suppress plasma cortisol levels
- Use of estrogen-containing drugs increases cortisol binding globulin levels which can elevate plasma total cortisol levels; to ensure accuracy of plasma total cortisol levels, discontinue estrogen-containing drugs 4-6 weeks prior to testing to allow cortisol binding globulin levels to return to levels within reference range; alternatively, concomitant measurement of cortisol binding globulin at time of testing can be done; if cortisol binding globulin levels are elevated, plasma total cortisol levels are considered inaccurate
Pregnancy & Lactation
Pregnancy
Safety in pregnant women not established; there are no adequate and well controlled studies of cosyntropin in pregnant women; therapy should be used during pregnancy only if potential benefit justifies potential risk to fetus
Lactation
Not known whether cosyntropin is excreted into human milk; because many drugs are excreted in human milk and because of potential for serious adverse reactions in nursing infants from cosyntropin, caution should be exercised when treatment is administered to a nursing woman
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Mimics natural ACTH; stimulates adrenal cortex to secrete adrenal steroids (cortisone and hydrocortisone), androgenic substances, and aldosterone
Pharmacokinetics
Duration: IM: <4 hr
Onset: IM: 1 hr
Time to peak plasma concentration: Within 1 hr (IM, IV push)
Bioavailability: Well absorbed from parenteral route
Vd: 43%
Half-life: 7 min
Metabolism: Unknown
Excretion: Urine
Absorption: Rapid (IM)
Administration
IV Incompatibilities
Compatibility of cosyntropin for injection with other drugs depends on several factors (eg, concentration of the drugs, specific diluents used, resulting pH, temperature)
IV/IM Administration
Administer by IM or IV injection or by IV infusion
