Glucocorticoids bind to the α-isoform only. Glucocorticoid receptors have two isoforms, α, and β.

Clinically, it is not possible to separate these effects.īeing small, lipophilic substances, glucocorticoids readily pass the cell membrane by diffusion and enter the cytoplasm of the target cells, where most of their action is mediated by binding to the intra-cytoplasmic glucocorticoid receptors. Most effects of glucocorticoids are via the genomic mechanisms, which takes time, while immediate effects via the non-genomic mechanisms can occur with high doses of glucocorticoids (such as pulse therapy). The anti-inflammatory and immunosuppressive effects of glucocorticoids are dose-dependent, with immunosuppressive effects seen mostly at higher doses. The pharmacological anti-inflammatory and immunosuppressive effects of glucocorticoids are extensive and can occur via genomic or non-genomic mechanisms. We have categorized and mentioned the most important and broad-spectrum indications below.Īnti-Inflammatory and Immunosuppressive Effects The list of indications of glucocorticoids is extremely long. Their actions are used medically for the treatment of various conditions indicated below. Glucocorticoids (GCs) are a group of drugs structurally and pharmacologically similar to the endogenous hormone cortisol with various functions like anti-inflammatory, immunosuppressive, anti-proliferative, and vaso-constrictive effects. Kendall, and Tadeusz Reichstein were awarded the Nobel Prize in Physiology or Medicine "for their discoveries relating to the hormones of the adrenal cortex, their structure, and biological effects." This case was published in 1949, and in 1950, Philip S. The patient was able to walk after three days of treatment. Philip S Hench published administered cortisone (called Compound E at that time) to a 29-year-old woman who was bed-ridden secondary to active rheumatoid arthritis. Endogenous cortisone was first isolated in 1935 and synthesized in 1944.

This activity reviews the must-know properties of this group of drugs, their broad indications and contraindications, ways of administration, adverse event profile, practical aspects of the pharmacokinetics of different molecules, monitoring essentials, approach to maximize the benefit and minimize adverse effects, and clinically relevant drug-interactions pertinent for all specialists whether used in isolation or administered by an interprofessional team.Ĭorticosteroids are hormone mediators produced by the cortex of adrenal glands that are further categorized into glucocorticoids (major glucocorticoid produced by the body is cortisol), mineralocorticoids (major mineralocorticoid produced in the body is aldosterone), and androgenic sex hormones. Corticosteroids are used across all medical specialties. Corticosteroids constitute a double-edged sword - significant benefit with a low incidence of adverse effects can be expected if used in proper dosage and for a limited duration however, wrong dose and/or duration and unmindful withdrawal after prolonged administration can have catastrophic effects. They are used in a plethora of conditions, commonly called steroid-responsive disorders and dermatoses. Corticosteroids are hormone mediators produced by the cortex of adrenal glands that further categorize into glucocorticoids, mineralocorticoids, and androgenic sex hormones.
