Mometasone furoate is used in the treatment of inflammatory skin disorders (such as eczema and psoriasis) (topical form), allergic rhinitis (such as hay fever) (topical form), asthma (inhalation form) for patients unresponsive to less potent corticosteroids, and penile phimosis. In terms of steroid strength, it is more potent than hydrocortisone, and less potent than dexamethasone.
Some low-quality evidence suggests the use of mometasone for symptomatic improvement in children with adenoid hypertrophy.
Mometasone is used to alleviate inflammation and itchiness in skin conditions that respond to treatment with glucocorticoids such as psoriasis and atopic dermatitis
Nasal mometasone is used in adults (including the elderly) and children over 2 years to diminishing the symptoms such as hay fever (seasonal allergic rhinitis) and other allergies (perennial rhinitis), including nasal congestion, discharge, pruritus, and sneezing and to treat nasal polyps.
Mometasone furoate can be used with formoterol for the treatment of asthma, due to its anti-inflammatory properties.
It reduces inflammation by causing several effects:Reversing the activation of inflammatory proteins
Activating the secretion of anti-inflammatory proteins
Stabilizing cell membranes
Decreasing the influx of inflammatory cells
In addition to the glucocorticoid properties of mometasone furoate, it is a very potent agonist of the progesterone receptor as well as a partial agonist of the mineralocorticoid receptor.
Mometasone, like other corticosteroids, possesses anti-inflammatory, antipruritic, and vasoconstrictive properties. For allergies, corticosteroids reduce the allergic reactions in various types of cells (mastocytes and eosinophils) that are responsible for allergic reactions. Mometasone and other corticosteroids circulate in the blood easily, crossing cellular membranes and binding with cytoplasmic receptors, resulting in the transcription and synthesis of proteins. It also inhibits the actions of the enzyme cytochrome P450 2C8 which participates in the activity of monooxygenase.
The inflammation is reduced in decreasing the liberation of hydrolace acids of leukocytes, the prevention of the accumulation macrophages in the sites of inflammation, the interference with adhesion of leukocytes to capillary walls, the reduction of the permeability of the capillary membranes and consequently edema, the reduction of complementary components, inhibition of histamine and kinin liberation, and interference with scar tissue formation. The proliferation of fibroblasts and collagen deposits are also reduced. It is believed that the action of corticosteroid anti-inflammatory agents are bound to inhibitive proteins of phospholipase A2, collectively called lipocortins. The lipocortins, in turn, control the biosynthesis of potent mediators of inflammation as the prostaglandins and leukotrienes, inhibiting the liberation of the molecular precursors of arachidonic acid. Intranasal mometasone alleviates symptoms such as rhinorrhea aquosa, nasal congestion, nasal drip, sneezing, and pharyngeal itching. Topical administration applied to skin reduces the inflammation associated with chronic or acute dermatosis.
Extensive metabolic hepatic metabolism to multiple metabolites occurs. No principal metabolites are detectable in plasma. After in vitro incubation, one of the minor metabolites formed is furoate 6β-hydroxymometasone. In human hepatic microsomes, the formation of these metabolites is regulated by CYP3A4.
