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 hydrolase 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 is also reduced. It is believed that the action of corticosteroid anti-inflammatory agents is 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. Although mometasone furoate does not have significant systemic immunomodulatory effects, it can be considered a local immunosuppressive drug because clinical studies have shown reductions (vs. baseline ) in neutrophils (a white blood cell) in the nasal mucosa. It could be also considered an antihistamine along with its glucocorticoid effects because it significantly reduces histamine and eosinophil cationic protein levels.
Mometasone, also known as mometasone y 3 s, is a steroid medication used to treat certain skin conditions, hay fever, and asthma. Specifically it is used to prevent rather than treat asthma attacks. It can be applied to the skin, inhaled, or used in the nose. Mometasone furoate, not mometasone, is used in medical products.Common side effects when used for asthma includes asthma and thrush. It is therefore recommended to rinse the mouth after use. Long term use may increase the risk for glaucoma and cataracts. Common side effects when used in the nose includes upper respiratory tract infections and nose bleeds. Common side effects when applied on the skin include acne, skin atrophy, and itchiness. It works by decreasing inflammation.Mometasone furoate was patented in 1981 and came into medical use in 1987. It is on the World Health Organizations List of Essential Medicines. It is available as a generic medication. In 2017, it was the 197th most commonly prescribed medication in the United States, with more than two million prescriptions. Medical uses
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.
