• Glucocorticoids such as cortisol affect carbohydrate, fat, and protein metabolism, and have anti-inflammatory, immunosuppressive, anti-proliferative, and vasoconstrictive effects.{{cite journal | vauthors = Liu D, Ahmet A, Ward L, Krishnamoorthy P, Mandelcorn ED, Leigh R, Brown JP, Cohen A, Kim H | display-authors = 6 | title = A practical guide to the monitoring and management of the complications of systemic corticosteroid therapy | journal = Allergy, Asthma, and Clinical Immunology | volume = 9 | issue = 1 | pages = 30 | date = August 2013 | pmid = 23947590 | pmc = 3765115 | doi = 10.1186/1710-1492-9-30 | doi-access = free }} Anti-inflammatory effects are mediated by blocking the action of inflammatory mediators (transrepression) and inducing anti-inflammatory mediators (transactivation). Immunosuppressive effects are mediated by suppressing delayed hypersensitivity reactions by direct action on T-lymphocytes. Anti-proliferative effects are mediated by inhibition of DNA synthesis and epidermal cell turnover. Vasoconstrictive effects are mediated by inhibiting the action of inflammatory mediators such as histamine.
• Mineralocorticoids such as aldosterone are primarily involved in the regulation of electrolyte and water balance by modulating ion transport in the epithelial cells of the renal tubules of the kidney.

Synthetic pharmaceutical drugs with corticosteroid-like effects are used in a variety of conditions, ranging from hematological neoplasms{{cite journal | vauthors = Faggiano A, Mazzilli R, Natalicchio A, Adinolfi V, Argentiero A, Danesi R, D'Oronzo S, Fogli S, Gallo M, Giuffrida D, Gori S, Montagnani M, Ragni A, Renzelli V, Russo A, Silvestris N, Franchina T, Tuveri E, Cinieri S, Colao A, Giorgino F, Zatelli MC | display-authors = 6 | title = Corticosteroids in oncology: Use, overuse, indications, contraindications.

Dexamethasone and its derivatives are almost pure glucocorticoids, while prednisone and its derivatives have some mineralocorticoid action in addition to the glucocorticoid effect. Fludrocortisone (Florinef) is a synthetic mineralocorticoid. Hydrocortisone (cortisol) is typically used for replacement therapy, e.g. for adrenal insufficiency and congenital adrenal hyperplasia.{{cn|date=June 2024}}

Topical formulations are also available for the skin, eyes (uveitis), lungs (asthma), nose (rhinitis), and bowels. Corticosteroids are also used supportively to prevent nausea, often in combination with 5-HT₃ antagonists (e.g., ondansetron).{{cn|date=June 2024}}

Typical undesired effects of glucocorticoids present quite uniformly as drug-induced Cushing's syndrome. Typical mineralocorticoid side-effects are hypertension (abnormally high blood pressure), steroid induced diabetes mellitus, psychosis, poor sleep, hypokalemia (low potassium levels in the blood), hypernatremia (high sodium levels in the blood) without causing peripheral edema, metabolic alkalosis and connective tissue weakness.{{cite book| vauthors = Werner R |title=A massage therapist's guide to Pathology |publisher=Lippincott Williams & Wilkins |location=Pennsylvania |year=2005 |edition=3rd }} Wound healing or ulcer formation may be inhibited by the immunosuppressive effects.

Patients' response to inhaled corticosteroids has some basis in genetic variations. Two genes of interest are CHRH1 (corticotropin-releasing hormone receptor 1) and TBX21 (transcription factor T-bet). Both genes display some degree of polymorphic variation in humans, which may explain how some patients respond better to inhaled corticosteroid therapy than others.{{cite journal | vauthors = Tantisira KG, Lake S, Silverman ES, Palmer LJ, Lazarus R, Silverman EK, Liggett SB, Gelfand EW, Rosenwasser LJ, Richter B, Israel E, Wechsler M, Gabriel S, Altshuler D, Lander E, Drazen J, Weiss ST | display-authors = 6 | title = Corticosteroid pharmacogenetics: association of sequence variants in CRHR1 with improved lung function in asthmatics treated with inhaled corticosteroids | journal = Human Molecular Genetics | volume = 13 | issue = 13 | pages = 1353–1359 | date = July 2004 | pmid = 15128701 | doi = 10.1093/hmg/ddh149 | doi-access = free }}{{cite journal | vauthors = Tantisira KG, Hwang ES, Raby BA, Silverman ES, Lake SL, Richter BG, Peng SL, Drazen JM, Glimcher LH, Weiss ST | display-authors = 6 | title = TBX21: a functional variant predicts improvement in asthma with the use of inhaled corticosteroids | journal = Proceedings of the National Academy of Sciences of the United States of America | volume = 101 | issue = 52 | pages = 18099–18104 | date = December 2004 | pmid = 15604153 | pmc = 539815 | doi = 10.1073/pnas.0408532102 | doi-access = free | bibcode = 2004PNAS..10118099T }} However, not all asthma patients respond to corticosteroids and large sub groups of asthma patients are corticosteroid resistant.{{cite journal | vauthors = Peters MC, Kerr S, Dunican EM, Woodruff PG, Fajt ML, Levy BD, Israel E, Phillips BR, Mauger DT, Comhair SA, Erzurum SC, Johansson MW, Jarjour NN, Coverstone AM, Castro M, Hastie AT, Bleecker ER, Wenzel SE, Fahy JV | display-authors = 6 | title = Refractory airway type 2 inflammation in a large subgroup of asthmatic patients treated with inhaled corticosteroids | journal = The Journal of Allergy and Clinical Immunology | volume = 143 | issue = 1 | pages = 104–113.e14 | date = January 2019 | pmid = 29524537 | pmc = 6128784 | doi = 10.1016/j.jaci.2017.12.1009 }}

A study funded by the Patient-Centered Outcomes Research Institute of children and teens with mild persistent asthma found that using the control inhaler as needed worked the same as daily use in improving asthma control, number of asthma flares, how well the lungs work, and quality of life.

• Cardiovascular: Corticosteroids can cause sodium retention through a direct action on the kidney, in a manner analogous to the mineralocorticoid aldosterone. This can result in fluid retention and hypertension.
• Metabolic: Corticosteroids cause a movement of body fat to the face and torso, resulting in "moon face", "buffalo hump", and "pot belly" or "beer belly", and cause movement of body fat away from the limbs. This has been termed corticosteroid-induced lipodystrophy. Due to the diversion of amino-acids to glucose, they are considered anti-anabolic, and long term therapy can cause muscle wasting (muscle atrophy).{{cite journal | vauthors = Hasselgren PO, Alamdari N, Aversa Z, Gonnella P, Smith IJ, Tizio S | title = Corticosteroids and muscle wasting: role of transcription factors, nuclear cofactors, and hyperacetylation | journal = Current Opinion in Clinical Nutrition and Metabolic Care | volume = 13 | issue = 4 | pages = 423–428 | date = July 2010 | pmid = 20473154 | pmc = 2911625 | doi = 10.1097/MCO.0b013e32833a5107 }} Besides muscle atrophy, steroid myopathy includes muscle pains (myalgias), muscle weakness (typically of the proximal muscles), serum creatine kinase normal, EMG myopathic, and some have type II (fast-twitch/glycolytic) fibre atrophy.{{cite journal | vauthors = Rodolico C, Bonanno C, Pugliese A, Nicocia G, Benvenga S, Toscano A | title = Endocrine myopathies: clinical and histopathological features of the major forms | journal = Acta Myologica | volume = 39 | issue = 3 | pages = 130–135 | date = September 2020 | pmid = 33305169 | pmc = 7711326 | doi = 10.36185/2532-1900-017 }}

The corticosteroids are synthesized from cholesterol within the adrenal cortex. Most steroidogenic reactions are catalysed by enzymes of the cytochrome P450 family. They are located within the mitochondria and require adrenodoxin as a cofactor (except 21-hydroxylase and 17α-hydroxylase).{{cn|date=June 2024}}

Aldosterone and corticosterone share the first part of their biosynthetic pathway. The last part is mediated either by the aldosterone synthase (for aldosterone) or by the 11β-hydroxylase (for corticosterone). These enzymes are nearly identical (they share 11β-hydroxylation and 18-hydroxylation functions), but aldosterone synthase is also able to perform an 18-oxidation. Moreover, aldosterone synthase is found within the zona glomerulosa at the outer edge of the adrenal cortex; 11β-hydroxylase is found in the zona fasciculata and zona glomerulosa.{{cn|date=June 2024}}

In general, corticosteroids are grouped into four classes, based on chemical structure. Allergic reactions to one member of a class typically indicate an intolerance of all members of the class. This is known as the "Coopman classification".{{cite book | vauthors = Rietschel RL |title=Fisher's Contact Dermatitis, 6/e |publisher=BC Decker Inc |location=Hamilton, Ont |year=2007 |page=256 |isbn=978-1-55009-378-0 }}{{cite journal | vauthors = Coopman S, Degreef H, Dooms-Goossens A | title = Identification of cross-reaction patterns in allergic contact dermatitis from topical corticosteroids | journal = The British Journal of Dermatology | volume = 121 | issue = 1 | pages = 27–34 | date = July 1989 | pmid = 2757954 | doi = 10.1111/j.1365-2133.1989.tb01396.x | s2cid = 40425526 }}

{{Main|Topical steroid}}

For use topically on the skin, eye, and mucous membranes.

Topical corticosteroids are divided in potency classes I to IV in most countries (A to D in Japan). Seven categories are used in the United States to determine the level of potency of any given topical corticosteroid.

For nasal mucosa, sinuses, bronchi, and lungs.{{cite web|url=http://www.webmd.com/asthma/guide/asthma_control_with_anti-inflammatory-drugs |title=Asthma Steroids: Inhaled Steroids, Side Effects, Benefits, and More |publisher=Webmd.com |access-date=2012-11-30}}

Tadeusz Reichstein, Edward Calvin Kendall, and Philip Showalter Hench were awarded the Nobel Prize for Physiology and Medicine in 1950 for their work on hormones of the adrenal cortex, which culminated in the isolation of cortisone.{{cite journal | vauthors = Kendall EC | title = The development of cortisone as a therapeutic agent | journal = Antibiotics & Chemotherapy (Northfield, Ill.) | volume = 1 | issue = 1 | pages = 7–15 | date = April 1951 | pmid = 24540604 | doi = | url = http://nobelprize.org/nobel_prizes/medicine/laureates/1950/kendall-lecture.pdf |archive-url=https://web.archive.org/web/20170415234708/http://www.nobelprize.org/nobel_prizes/medicine/laureates/1950/kendall-lecture.pdf | archive-date = 15 April 2017 |url-status=dead }}

Initially hailed as a miracle cure and liberally prescribed during the 1950s, steroid treatment brought about adverse events of such a magnitude that the next major category of anti-inflammatory drugs, the nonsteroidal anti-inflammatory drugs (NSAIDs), was so named in order to demarcate from the opprobrium.{{cite journal | vauthors = Buer JK | title = Origins and impact of the term 'NSAID' | journal = Inflammopharmacology | volume = 22 | issue = 5 | pages = 263–267 | date = October 2014 | pmid = 25064056 | doi = 10.1007/s10787-014-0211-2 | hdl-access = free | s2cid = 16777111 | hdl = 10852/45403 }}

Lewis Sarett of Merck & Co. was the first to synthesize cortisone, using a 36-step process that started with deoxycholic acid, which was extracted from ox bile.{{cite patent | inventor = Sarett LH | gdate = 1947 | title = Process of Treating Pregnene Compounds | country = US | number = 2462133 }} The low efficiency of converting deoxycholic acid into cortisone led to a cost of US$200 per gram in 1947. Russell Marker, at Syntex, discovered a much cheaper and more convenient starting material, diosgenin from wild Mexican yams. His conversion of diosgenin into progesterone by a four-step process now known as Marker degradation was an important step in mass production of all steroidal hormones, including cortisone and chemicals used in hormonal contraception.{{cite journal | vauthors = Marker RE, Wagner RB | title = Steroidal sapogenins | journal = Journal of the American Chemical Society | volume = 69 | issue = 9 | pages = 2167–2230 | date = September 1947 | pmid = 20262743 | doi = 10.1021/ja01201a032 | bibcode = 1947JAChS..69.2167M }}

In 1952, D.H. Peterson and H.C. Murray of Upjohn developed a process that used Rhizopus mold to oxidize progesterone into a compound that was readily converted to cortisone.{{cite journal |vauthors=Peterson DH, Murray HC |title=Microbiological Oxygenation of Steroids at Carbon 11 |journal=J. Am. Chem. Soc. |volume=74 |issue=7 |pages=1871–2 |year=1952 |doi=10.1021/ja01127a531 |bibcode=1952JAChS..74.1871P }} The ability to cheaply synthesize large quantities of cortisone from the diosgenin in yams resulted in a rapid drop in price to US$6 per gram{{when|date=August 2023}}, falling to $0.46 per gram by 1980. Percy Julian's research also aided progress in the field.{{cite patent | inventor = Julian L, Cole JW, Meyer EW, Karpel WJ | gdate = 1956 | title = Preparation of Cortisone | country = US | number = 2752339 }} The exact nature of cortisone's anti-inflammatory action remained a mystery for years after, however, until the leukocyte adhesion cascade and the role of phospholipase A2 in the production of prostaglandins and leukotrienes was fully understood in the early 1980s.{{Citation needed|date=July 2024}}
