      Drug Name Conjugated estrogens (topical) Budesonide
      Mechanism Increase serum cortisol-binding globulin concentration Corticosteroid
      Key Mechanism Factor 1
Factor Name Pharmacokinetics
Factor Description Alters the distribution of the drug, leading to changes in the plasma concentration of the drug and affecting the pharmacological effects.
      Mechanism Description
  • Decreased plasma concentration of Budesonide caused by Conjugated estrogens (topical) mediated increased concentration of serum thyroid-binding globulin

Recommended Action
      Management Patients treated concomitantly with an estrogen-containing drug may require lower dosages of corticosteroids or adrenocorticotropic agents. Pharmacologic response to these agents should be monitored more closely whenever an estrogen is added to or withdrawn from therapy in patients stabilized on their existing corticosteroid or adrenocorticotropic regimen, and the dosage(s) adjusted as necessary.
