Kenalog-40 and Mifepristone Tablets

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Using miFEPRIStone together with triamcinolone is generally not recommended. Combining these medications may significantly reduce the effects of triamcinolone. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

CONTRAINDICATED: Mifepristone is a potent antiglucocorticoid and may antagonize the effects of corticosteroids. In animals, mifepristone at dosages of 10 to 25 mg/kg inhibited the action of dexamethasone. In human, the antiglucocorticoid action occurred at dosages of 4.5 mg/kg or greater, as indicated by a compensatory elevation of adrenocorticotropic hormone (ACTH) and cortisol. The efficacy of chronic corticosteroid therapy, including inhaled corticosteroids, may be reduced for 3 to 4 days after a single dose of mifepristone. Pharmacokinetically, mifepristone may increase the plasma concentrations of corticosteroids by inhibiting their metabolism via CYP450 3A4. However, the clinical impact has not been studied. Dexamethasone, specifically, may also decrease the blood levels of mifepristone by inducing its metabolism via CYP450 3A4.

MANAGEMENT: The use of mifepristone is considered contraindicated in patients on long-term corticosteroid therapy. When intended for daily use to control hyperglycemia secondary to hypercortisolism in patients with endogenous Cushing's syndrome, mifepristone is also contraindicated in those patients who require systemic corticosteroids for serious medical conditions or illnesses, such as immunosuppression after organ transplantation. Because mifepristone is eliminated slowly from the body, drug interactions may be observed for a prolonged period following discontinuation (approximately 2 to 3 weeks if mifepristone had been administered chronically to steady state).
