Cortisone (DB14681): A Comprehensive Monograph on its Pharmacology, Clinical Utility, and Historical Significance

Executive Summary

Cortisone is a foundational glucocorticoid hormone that has profoundly shaped modern medicine since its therapeutic potential was first realized in the mid-20th century. This report provides an exhaustive analysis of Cortisone, integrating its physicochemical properties, historical context, complex pharmacology, clinical applications, and evolving regulatory status. Identified chemically as a pregnene-based steroid, Cortisone functions as a biologically inactive prodrug, requiring hepatic conversion to its active metabolite, cortisol (hydrocortisone), to exert its effects. This activation is part of an elegant physiological system of tissue-specific hormone regulation that is co-opted for therapeutic purposes.

The pharmacological actions of Cortisone are mediated through both slow, genomic pathways and rapid, non-genomic mechanisms. The classic genomic pathway involves the binding of cortisol to intracellular glucocorticoid receptors, which then translocate to the nucleus to modulate the transcription of a wide array of genes, ultimately suppressing the synthesis of pro-inflammatory mediators and promoting anti-inflammatory signals. These effects are responsible for the drug's potent, broad-spectrum anti-inflammatory and immunosuppressive activities, which form the basis of its use in a vast range of conditions, including endocrine, rheumatic, allergic, and autoimmune disorders.
