Amcinonide is a synthetic glucocorticoid receptor agonist that mimics the metabolic, anti-inflammatory, and immunosuppressive activity of the natural glucocorticoids. Amcinonide interacts with specific corticosteroid receptors and was internalized, which leads to binding of DNA and modification of gene expression. This results in synthesis of anti-inflammatory mediators while inhibiting synthesis of inflammatory mediators. Consequently, an overall reduction in chronic inflammation and autoimmune reactions are achieved.
Amcinonide is a Corticosteroid. The mechanism of action of amcinonide is as a Corticosteroid Hormone Receptor Agonist.

FDA Label


5 Pharmacology and Biochemistry
5.1 Pharmacology

Amcinonide is a topical corticosteroid. The topical corticosteroids constitute a class of primarily synthetic steroids used as anti-inflammatory and antipruritic agents. Amcinonide reduces or inhibits the actions of chemicals in the body that cause inflammation, redness, and swelling. The mechanism of anti-inflammatory activity of the topical corticosteroids is unclear. Various laboratory methods, including vasoconstrictor assays, are used to compare and predict potencies and/or clinical efficacies of the topical corticosteroids. There is some evidence to suggest that a recognizable correlation exists between vasoconstrictor potency and therapeutic efficacy in man. When in an ointment form, amcinonide also helps the skin maintain moisture.


5.2 MeSH Pharmacological Classification

Glucocorticoids

A group of CORTICOSTEROIDS that affect carbohydrate metabolism (GLUCONEOGENESIS, liver glycogen deposition, elevation of BLOOD SUGAR), inhibit ADRENOCORTICOTROPIC HORMONE secretion, and possess pronounced anti-inflammatory activity. They also play a role in fat and protein metabolism, maintenance of arterial blood pressure, alteration of the connective tissue response to injury, reduction in the number of circulating lymphocytes, and functioning of the central nervous system. (See all compounds classified as Glucocorticoids.)

5.5 Absorption, Distribution and Excretion

Absorption

Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin increase percutaneous absorption.


Route of Elimination

Corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile.


5.6 Metabolism/Metabolites

Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys.


5.7 Mechanism of Action

The mechanism of the anti-inflammatory activity of the topical steroids, in general, is unclear. However, corticosteroids are thought to act by the induction of phospholipase A2 inhibitory proteins, collectively called lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor, arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2. Amcinonide has affinity for the glucocorticoid receptor. It has weak affinity for the progesterone receptor, and virtually no affinity for the mineralocorticoid, estrogen, or androgen receptors.
