It is likely that much of the mechanism for the anti-allergic and anti-inflammatory effects of mometasone furoate lies in its ability to inhibit the release of mediators of allergic reactions. Mometasone furoate significantly inhibits the release of leukotrienes from leucocytes of allergic patients. In cell culture, mometasone furoate demonstrated high potency in inhibition of synthesis and release of IL-1, IL-5, IL-6 and TNFα; it is also a potent inhibitor of leukotriene production. In addition, it is an extremely potent inhibitor of the production of the Th2 cytokines, IL-4 and IL-5, from human CD4+ T-cells.

An allergy occurs when the body reacts to foreign particles it can't tolerate. These particles, such as tree pollen or dust mites, are called antigens, or allergens, and are normally harmless. But the immune system of a person with allergies views the allergens as harmful. Following the body’s first contact with an allergen, white blood cells produce antibodies that prepare the immune system for the same allergen the next time it enters the body. Antibodies attach themselves to cells such as basophils and mast cells. Later contact with even a small amount of the allergen triggers the cells to release chemicals such as leukotrienes, prostaglandins, and histamine. When these chemicals are released, they attach to the receptors of nearby cells. The binding causes swelling of nasal blood vessels and inflammation of membranes. This results in common allergy symptoms such as: • sneezing • itchiness • watery nose • and congestion Normally to reduce inflammation, the brain signals the adrenal glands to produce a hormone called cortisol. Cortisol works against allergens by acting on receptors in the cytoplasm of various cells. Once bound, cortisol-receptor complex enters into the nucleus. There it binds to the DNA and prevents the creation of proteins responsible for the release of inflammatory chemicals. As a result, when the allergen binds to the antibodies on the cell, the cell is not triggered to release inflammatory chemicals. Sometimes cortisol is not able to control the immune system response. In this case, nasal corticosteroids, synthetically-produced hormones similar to cortisol, may be prescribed. When inhaled, they bind to receptors and the complex works in the same way as cortisol. Therefore, when the allergen binds to the antibodies on the cell, the inflammatory chemicals are not released. As a result, the immune system’s response is decreased and symptoms are reduced. While effective, corticosteroids are not right for everyone and can cause minor as well as serious side effects, so a corticosteroid therapy should only be started under the care and guidance of a physician.

Single dose intranasal administration of 220 micrograms of Nasacort Allergy or Triamcinolone Nasal Spray in normal adult subjects and in adult patients with allergic rhinitis demonstrated minimal absorption of triamcinolone acetonide. The mean peak plasma concentration was approximately ng/mL (range to 1 ng/mL) and occurred at hours post dose. The mean plasma drug concentration was less than ng/mL at 12 hours and below the assay detection limit at 24 hours. The average terminal half life was hours. Dose proportionality was demonstrated in normal subjects and in patients following a single intranasal dose of 110 micrograms or 220 micrograms Nasacort Allergy or Triamcinolone Nasal Spray. Following multiple doses in paediatric patients, plasma drug concentrations, AUC, C max and T max were similar to those values observed in adult patients.
