Nasal Steroid Preparations
Avamist 27.5 mcg/spray is a synthetic trifluorinated corticosteroid with potent anti-inflammatory activity. Like other corticosteroids Avamist 27.5 mcg/spray is found to have a wide range of actions on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, lymphocytes) and mediators (e.g.- histamine, eicosanoids, leukotrienes, cytokines) involved in inflammation.
Dosage of Avamist 27.5 mcg/spray
Avamist 27.5 mcg/spray Nasal Spray:
Adults & Children over 12 years: 2 sprays in each nostril once a day. In some cases 2 sprays into each nostril twice daily, not exceeding 4 sprays.
Children under 12 years (2-11 Years): 1 spray in each nostril once a day. Patients should use Avamist 27.5 mcg/spray nasal spray at regular intervals as directed since its effectiveness depends on its regular use.
Children (under 2 years of age): There are no data to recommend use of Avamist 27.5 mcg/spray Nasal Spray for the treatment of seasonal or perennial allergic rhinitis in children under 2 years of age.
Avamist 27.5 mcg/spray Inhalation Capsule: should be administered as 1 inhalation once daily by the orally inhaled route. Avamist 27.5 mcg/spray should be used at the same time every day. Do not use Avamist 27.5 mcg/spray more than 1 time every 24 hours.
Adults and Adolescents Aged 12 Years and Older: The starting dosage for Avamist 27.5 mcg/spray should be based upon patients' asthma severity.
The usual recommended starting dose for adults and adolescents aged 12 years and older not on an inhaled corticosteroid (ICS) is 100 mcg.
For other adults and adolescents aged 12 years and older, the starting dose should be based on previous asthma drug therapy and disease severity.
For adults and adolescents aged 12 years and older who do not respond to Avamist 27.5 mcg/spray 100 mcg after 2 weeks of therapy, replacement with Avamist 27.5 mcg/spray 200 mcg may provide additional asthma control.
If a dosage regimen of Avamist 27.5 mcg/spray fails to provide adequate control of asthma, the therapeutic regimen should be re-evaluated and additional therapeutic options, e.g., replacing the current strength of Avamist 27.5 mcg/spray with a higher strength, initiating an ICS and long- acting beta 2 -agonist (LABA) combination product, or initiating oral corticosteroids, should be considered.The highest recommended daily dose in adults and adolescents aged 12 years and older is 200 mcg. After asthma stability has been achieved, it is desirable to titrate to the lowest effective dosage to help reduce the possibility of side effects.Pediatric Patients Aged 5 to 11 Years: The recommended dosage for children aged 5 to 11 years is 50 mcg administered once daily
