National Library of Medicine's Medical Subject Headings online file (MeSH, 1999)


Nasal corticosteroids are used in some patients for prophylaxis of seasonal rhinitis. This form of therapy is generally reserved for patients who have consistently demonstrated a need for nasal corticosteroids to control seasonal rhinitis syndromes. Antihistamines and decongestants are considered primary therapies for this disorder. Dexamethasone nasal aerosol is less frequently used because its use results in a significantly higher incidence of systemic adverse effects with no additional benefit over other nasal corticosteroids. /NOT included in US product labeling/

4.3 Drug Warning

Dexamethasone improves the cure rate of childhood acute lymphoblastic leukemia (ALL) but causes physical and behavioral adverse events. The objective of the current study was to determine the effect of dexamethasone exposure on sleep and fatigue in pediatric patients with acute lymphoblastic leukemia. One hundred pediatric patients with low-risk or standard-risk acute lymphoblastic leukemia were enrolled on 1 of 3 protocols (St. Jude Total XV, Children's Oncology Group [COG] 9904, or COG 9905) at 3 institutions. The mean age of the cohort was 9.24 +/- 3.23 years (range, 5.03-18.14 years). The majority of patients were white (79%) males (62%) with standard-risk acute lymphoblastic leukemia (63%). The cohort was divided into 4 subgroups: St. Jude low-risk, St. Jude standard-risk, COG low-risk, and COG standard-risk. Patients wore a wrist actigraph to monitor sleep activity during 2 consecutive 5-day periods: During the first period, they did not receive dexamethasone; and, during the second period, they did. Patients and their parents completed fatigue instruments on Days 2 and 5 of each period, and parents completed sleep diaries. Actual sleep minutes, sleep duration, total daily nap minutes, and fatigue increased significantly during the dexamethasone treatment for 3 to 4 of the subgroups. Total daily nap minutes increased significantly for both standard-risk groups during the dexamethasone treatment. Parents reported significant increases in their child's nighttime awakenings, restless sleep, and nap time during dexamethasone treatment.Dexamethasone treatment during continuation therapy for childhood acute lymphoblastic leukemia significantly and adversely altered sleep and fatigue, confirming that sleep and fatigue are behavioral responses to dexamethasone.

Dexamethasone inhalation is not recommended for use in asthma because it has demonstrated a significantly higher incidence of systemic effects with no additional benefit over other inhaled corticosteroids. The high ratio of systemic glucocorticoid activity to local anti-inflammatory activity of inhaled dexamethasone may be due to its greater water solubility and longer metabolic hal life after absorption relative to the other inhaled corticosteroids.

5 Pharmacology and Biochemistry
5.1 Pharmacology

Corticosteroids bind to the glucocorticoid receptor, inhibiting pro-inflammatory signals, and promoting anti-inflammatory signals. Dexamethasone's duration of action varies depending on the route. Corticosteroids have a wide therapeutic window as patients may require doses that are multiples of what the body naturally produces. Patients taking corticosteroids should be counselled regarding the risk of hypothalamic-pituitary-adrenal axis suppression and increased susceptibility to infections.


5.2 MeSH Pharmacological Classification

Anti-Inflammatory Agents

Substances that reduce or suppress INFLAMMATION. (See all compounds classified as Anti-Inflammatory Agents.)


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.)


Antineoplastic Agents, Hormonal

Antineoplastic agents that are used to treat hormone-sensitive tumors. Hormone-sensitive tumors may be hormone-dependent, hormone-responsive, or both. A hormone-dependent tumor regresses on removal of the hormonal stimulus, by surgery or pharmacological block. Hormone-responsive tumors may regress when pharmacologic amounts of hormones are administered regardless of whether previous signs of hormone sensitivity were observed. The major hormone-responsive cancers include carcinomas of the breast, prostate, and endometrium; lymphomas; and certain leukemias. (From AMA Drug Evaluations Annual 1994, p2079) (See all compounds classified as Antineoplastic Agents, Hormonal.)

5.5 Absorption, Distribution and Excretion

Absorption

Absorption via the intramuscular route is slower than via the intravenous route. A 3mg intramuscular dose reaches a Cmax of 34.66.0ng/mL with a Tmax of 2.01.2h and an AUC of 11338ng\*h/mL. A 1.5mg oral dose reaches a Cmax of 13.96.8ng/mL with a Tmax of 2.00.5h and an AUC of 33150ng\*h/mL. Oral dexamethasone is approximately 70-78% bioavailable in healthy subjects.


Route of Elimination

Corticosteroids are generally eliminated predominantly in the urine. However, dexamethasone is <10% elminated in urine.


Volume of Distribution

A 1.5mg oral dose of dexamethasone has a volume of distribution of 51.0L, while a 3mg intramuscular dose has a volume of distribution of 96.0L.


Clearance

A 20mg oral tablet has a clearance of 15.7L/h. A 1.5mg oral dose of dexamethasone has a clearance of 15.64.9L/h while a 3.0mg intramuscular dose has a clearance of 9.91.4L/h.


Absorbed into aqueous humor, cornea, iris, choroid ciliary body, and retina. Systemic absorption occurs, but may be significant only at higher dosages or in extended pediatric therapy. /Corticosteroids (Ophthalmic)/

Dogs (mixed-breed) were administered dexamethasone alcohol or dexamethasone 21-isonicotinate as a solution iv or im (1 mg/kg bw), or dexamethasone 21-isonicotinate as a suspension im (0.1 or 1 mg/kg bw). Plasma concentrations were determined with HPLC up to 120 hours after treatment. The elimination half-life after iv administration was 120-140 minutes for both formulations. Following im administration, absorption was rapid with peak plasma concentrations at 30-40 minutes for both solutions. Bioavailability after im administration was 100% for dexamethasone alcohol but 40% for dexamethasone 21-isonicotinate. After im administration of dexamethasone 21-isonicotinate as a suspension, dexamethasone was not detected in plasma, suggesting a long absorption phase

5.6 Metabolism/Metabolites

Dexamethasone is 6-hydroxylated by CYP3A4 to 6- and 6-hydroxydexamethasone. Dexamethasone is reversibly metabolized to 11-dehydrodexamethasone by corticosteroid 11-beta-dehydrogenase isozyme 2 and can also be converted back to dexamethasone by Corticosteroid 11-beta-dehydrogenase isozyme 1.


Male Wistar albino rats were administered (3)H-dexamethasone orally at a dose of 1.14 nmol/kg bw. Thirty-one percent of the administered radioactivity was excreted in the urine within 4 days (most of it within the first 24 hours) as unconjugated metabolites. Unchanged dexamethasone accounted for 14%, 6-hydroxydexamethasone for 7.4%, and 20-dihydrodexamethasone for 1.1% of the urine radioactivity.

5.8 Mechanism of Action

The short term effects of corticosteroids are decreased vasodilation and permeability of capillaries, as well as decreased leukocyte migration to sites of inflammation. Corticosteroids binding to the glucocorticoid receptor mediates changes in gene expression that lead to multiple downstream effects over hours to days. Glucocorticoids inhibit neutrophil apoptosis and demargination; they inhibit phospholipase A2, which decreases the formation of arachidonic acid derivatives; they inhibit NF-Kappa B and other inflammatory transcription factors; they promote anti-inflammatory genes like interleukin-10. Lower doses of corticosteroids provide an anti-inflammatory effect, while higher doses are immunosuppressive. High doses of glucocorticoids for an extended period bind to the mineralocorticoid receptor, raising sodium levels and decreasing potassium levels.


Corticosteroids diffuse across cell membranes and complex with specific cytoplasmic receptors. These complexes then enter the cell nucleus, bind to DNA, and stimulate transcription of mRNA and subsequent protein synthesis of enzymes ultimately responsible for anti-inflammatory effects of topical application of corticosteroids to the eye. In high concentrations which may be achieved after topical application, corticosteroids may exert direct membrane effects. Corticosteroids decrease cellular and fibrinous exudation and tissue infiltration, inhibit fibroblastic and collagen-forming activity, retard epithelial regeneration, diminish postinflammatory neovascularization and reduce toward normal levels the excessive permeability of inflamed capillaries. /Corticosteroids (Otic)/

Thomson/Micromedex. Drug Information for the Health Care Professional. Volume 1, Greenwood Village, CO. 2007., p. 911


Glucocorticoids are capable of suppressing the inflammatory process through numerous pathways. They interact with specific intracellular receptor proteins in target tissues to alter the expression of corticosteroid-responsive genes. Glucocorticoid-specific receptors in the cell cytoplasm bind with steroid ligands to form hormone-receptor complexes that eventually translocate to the cell nucleus. There these complexes bind to specific DNA sequences and alter their expression. The complexes may induce the transcription of mRNA leading to synthesis of new proteins. Such proteins include lipocortin, a protein known to inhibit PLA2a and thereby block the synthesis of prostaglandins, leukotrienes, and PAF. Glucocorticoids also inhibit the production of other mediators including AA metabolites such as COX, cytokines, the interleukins, adhesion molecules, and enzymes such as collagenase. /Glucocorticoids/

Corticosteroids diffuse across cell membranes and complex with specific cytoplasmic receptors. These complexes then enter the cell nucleus, bind to DNA (chromatin), and stimulate transcription of messenger RNA (mRNA) and subsequent protein synthesis of various inhibitory enzymes responsible for the anti-inflammatory effects of topical corticosteroids. These anti-inflammatory effects include inhibition of early processes such as edema, fibrin deposition, capillary dilatation, movement of phagocttes into the area, and phagocytic activities. Later processes, such as capillary production, collagen deposition, and keloid formation also are inhibited by corticosteroids. The overall actions of topical corticosteroids are catabolic. /Corticosteroids (topical)/
