4.2 Drug Indication

There are 3 formulations of mometasone furoate with various indications. The inhaler is indicated for prophylaxis of asthma in patients 4 years. The nasal spray is indicated for treating nasal symptoms of allergic rhinitis in patients 2 years, treating symptoms of nasal congestion from seasonal allergic rhinitis in patients 2 years, treating nasal polyps in patients 18 years, and prophylaxis of seasonal allergic rhinitis in patients 12 years. The ointment is indicated for symptomatic treatment of dermatitis and pruritis in patients 2 years.


FDA Label


Seasonal and perennial allergic rhinitis


5 Pharmacology and Biochemistry
5.1 Pharmacology

Mometasone is a synthetic corticosteroid with an affinity for glucocorticoid receptors 22 times higher than that of [dexamethasone]. Mometasone furoate also has a lower affinity to mineralocorticoid receptors than natural corticosteroids, making it more selective in its action. Mometasone furoate diffuses across cell membranes to activate pathways responsible for reducing inflammation.


5.2 MeSH Pharmacological Classification

Anti-Inflammatory Agents

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


Dermatologic Agents

Drugs used to treat or prevent skin disorders or for the routine care of skin. (See all compounds classified as Dermatologic Agents.)


Anti-Allergic Agents

Agents that are used to treat allergic reactions. Most of these drugs act by preventing the release of inflammatory mediators or inhibiting the actions of released mediators on their target cells. (From AMA Drug Evaluations Annual, 1994, p475) (See all compounds classified as Anti-Allergic Agents.)


5.3 FDA Pharmacological Classification
5.3.1 Pharmacological Classes
Corticosteroid Hormone Receptor Agonists [MoA]; Corticosteroid [EPC]; Corticosteroid Hormone Receptor Agonists [MoA]
5.4 Absorption, Distribution and Excretion

Absorption

The mean time to peak concentration is 1.0 to 2.5 hours. Bioavailability has been reported as <1% but studies of repeat doses of inhaled corticosteroids suggest a bioavailability of 11%. The 0.1% ointment may have a bioavailability of 0.7%.


Route of Elimination

For an inhaled dose, approximately 74% is excreted in the feces and 8% is excreted in the urine.


Volume of Distribution

Steady state volume of distribution of 152L.


Clearance

The clearance rate of mometasone furoate is not readily available, though it may be close to 90L/h.


5.5 Metabolism/Metabolites

Metabolism of mometasone furoate is largely performed hepatically by cytochrome P450 3A4 producing a number of metabolites. Some of these metabolites include free mometasone and 6-beta-hydroxy-mometasone furoate.


5.6 Biological Half-Life

The terminal half life of an inhaled dose is approximately 5 hours though it has been reported as 5.8 hours by other sources.


5.7 Mechanism of Action

In asthma, mometasone is believed to inhibit mast cells, eosinophils, basophils, and lymphocytes. There is also evidence of inhibition of histamine, leukotrienes, and cytokines. Corticosteroids diffuse across cell membranes into the cytosol of cells where they bind to glucocorticoid receptors to produce their activity. Mometasone furoate has a particularly high receptor affinity compare to other corticosteroids, 22 times higher than that of [dexamethasone]. Mometasone furoate binding to a glucocorticoid receptor causes conformational changes in the receptor, separation from chaperones, and the receptor moves to the nucleus. Once at the nucleus, receptors dimerize and bind to a DNA sequence known as the glucocorticoid response element which either increases expression of anti-inflammatory molecules or inhibits expression of pro-inflammatory molecules (such as interleukins 4 and 5). Mometasone furoate also reduces inflammation by blocking transcription factors such as activator-protein-1 and nuclear factor kappa B (NF-kappaB).
