Glucocorticoids are a class within the corticosteroid family. Glucocorticoids are chemically and functionally similar to endogenous cortisol. There are a wide array of indications, which primarily benefit from the antiinflammatory and immunosuppressive effects of this class of drugs. These medications are also used for conditions requiring physiologic glucocorticoid replacement. Despite their extensive use, glucocorticoids can produce many and varied adverse effects and should be used judiciously. Because of their immunosuppressive effect, these medications may predispose individuals to infection and should be avoided in those with uncontrolled infectionsInfectionsInvasion of the host organism by microorganisms or their toxins or by parasites that can cause pathological conditions or diseases.Chronic Granulomatous Disease.

Endogenous glucocorticoids are:
Derived from cholesterolCholesterolThe principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils.Cholesterol Metabolism (which is synthesized from acetyl-CoAAcetyl-CoAAcetyl CoA participates in the biosynthesis of fatty acids and sterols, in the oxidation of fatty acids and in the metabolism of many amino acids. It also acts as a biological acetylating agent.Citric Acid Cycle)
Secreted from the zona fasciculataZona FasciculataThe wide middle zone of the adrenal cortex. This zone produces a series of enzymes that convert pregnenolone to cortisol (hydrocortisone) via 17-alpha-hydroxyprogesterone.Adrenal Glands: Anatomy

GluconeogenesisGluconeogenesisGluconeogenesis is the process of making glucose from noncarbohydrate precursors. This metabolic pathway is more than just a reversal of glycolysis. Gluconeogenesis provides the body with glucose not obtained from food, such as during a fasting period. The production of glucose is critical for organs and cells that cannot use fat for fuel.

Translocation to the nucleusNucleusWithin a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (cell nucleolus). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the endoplasmic reticulum. A cell may contain more than one nucleus.The Cell: Organelles → bindBINDHyperbilirubinemia of the Newborn to specific DNADNAA deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).DNA Types and Structure sequences (glucocorticoid response elements) → result in either:
