Which steroid is supplied by Pfizer?

• A. Dexamethasone
• B. Betamethasone
• C. Hydrocortisone
• D. Methylprednisolone

Answer: (C)

Recognizing brand associations helps here: Pfizer is best known for hydrocortisone products, marketed as Cortef for oral use and Solu-Cortef for injection. Hydrocortisone (the endogenous glucocorticoid) is used for adrenal replacement and anti-inflammatory purposes, and its injectable form Solu-Cortef is a classic Pfizer product. The other steroids listed are produced by many manufacturers and are not uniquely linked to Pfizer in typical references, making hydrocortisone the best fit for “supplied by Pfizer.”
