Metasafe
Metasafe Uses, Dosage, Side Effects, Food Interaction and all others data.
Metasafe is a corticosteroid drug that can be used for the treatment of asthma, rhinitis, and certain skin conditions. It has a glucocorticoid receptor binding affinity 22 times stronger than dexamethasone and higher than many other corticosteroids as well. Metasafe is formulated as a dry powder inhaler, nasal spray, and ointment for its different indications.
Mometasone is a synthetic corticosteroid with an affinity for glucocorticoid receptors 22 times higher than that of dexamethasone. Metasafe also has a lower affinity to mineralocorticoid receptors than natural corticosteroids, making it more selective in its action. Metasafe diffuses across cell membranes to activate pathways responsible for reducing inflammation.

Uses
Metasafe is a corticosteroid used to treat asthma, allergic rhinitis, nasal congestion, nasal polyps, dermatitis, and pruritus.
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.
Metasafe is also used to associated treatment for these conditions: Allergic Rhinitis (AR), Asthma, Dermatitis, Dermatitis, Eczematous caused by superficial Fungal skin infection, Moderate to Severe Plaque Psoriasis, Polyps, Nasal, Pruritus, Psoriasis, Psoriasis, Moderate to Severe, Seasonal Allergies, Skin Diseases, Eczematous, Skin Infections
How Metasafe works
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. Metasafe has a particularly high receptor affinity compare to other corticosteroids, 22 times higher than that of dexamethasone. Metasafe 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). Metasafe also reduces inflammation by blocking transcription factors such as activator-protein-1 and nuclear factor kappa B (NF-kappaB).
Toxicity
Overdose with a mometasone furoate inhaler may occur with chronic overuse. Symptoms of chronic overuse may present as hypercorticism and adrenal suppression, and patients may not require any more treatment than monitoring.
In animal studies of pregnancy, some fetal toxic effects were seen at or above the maximum recommended human dose, though rodents are more sensitive to these effects than humans. The benefits and risks of use should be considered in pregnant patients
It is unknown if mometasone furoate is excreted in breast milk but other corticosteroids are and therefore caution should be exercised when administering to nursing mothers.
Safety and effectiveness in pediatric populations has been established through clinical trials, though there may be a reduction in expected growth of about 1cm per year depending on the dose and duration of treatment. Pediatric patients should be titrated to the lowest effective dose for mometasone furoate inhalers.
A trial of geriatric patients showed no difference in safety or efficacy compared to younger patients, however patients of an even greater age may still be more sensitive to mometasone furoate.
The use of a mometasone furoate inhaler in moderate or severe hepatic impairment rarely leads to detectable plasma concentrations though caution may be prudent with increasing degrees of severity.
The effects of mometasone furoate in renal impairment, and across gender and race have not been studied.
Food Interaction
No interactions found.Volume of Distribution
Steady state volume of distribution of 152L.
Elimination Route
["\"Official drug label\" href=\"#label-reference","Label<\/a> but studies of repeat doses of inhaled corticosteroids suggest a bioavailability of 11%. The 0.1% ointment may have a bioavailability of 0.7%.<\/p>\n"]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.
Clearance
The clearance rate of mometasone furoate is not readily available, though it may be close to 90L/h.
Elimination Route
For an inhaled dose, approximately 74% is excreted in the feces and 8% is excreted in the urine.
