Description
Curator's Comment: description was created based on several sources, including, http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2763756/

Deflazacort is a glucocorticoid developed for the treatment of different inflammatory and immune conditions. The drug is rapidly metabolized to an active metabolite, 21-hydroxy-deflazaxort that may cross the blood brain barrier. Deflazacort acts by suppressing inflammatory response.

Sample Use Guides

In Vivo Use Guide
The usual dose for most conditions, including rheumatoid arthritis is half to three tablets each day, the dose for severe asthma may be up to 8 or 12 tablets each day.
Route of Administration: Oral
In Vitro Use Guide
Phytohaemagglutinin stimulated peripheral blood lymphocytes, NK and K cells were incubated with different concentrations of the drug (0, 1.2, 6.0, 24, 60, 240, and 600 x 10(-7) M) and the immunosuppressive effect was measured. Deflazacort suppressed the cells in a dose dependent way.
