Higher doses of inhaled beclomethasone (more than 1000 mcg/day) may result in more absorption into the body. This may decrease bone formation and increase bone breakdown (resorption), resulting in weak bones and a risk of fractures . Even higher doses (more than 1500 mcg/day in adults and 400 mcg/day in children) may suppress the adrenal glands and impair their ability to make natural glucocorticoid. Patients with such suppression (which can be identified by testing) need increased amounts of glucocorticoid orally or by the intravenous route during periods of high physical stress since higher amounts of glucocorticoids are needed by the body to fight physical stress.
The first isolation and structure identifications of prednisone and prednisolone were done in 1950 by Arthur Nobile .    The first commercially feasible synthesis of prednisone was carried out in 1955 in the laboratories of Schering Corporation, which later became Schering-Plough Corporation , by Arthur Nobile and coworkers.  They discovered that cortisone could be microbiologically oxidized to prednisone by the bacterium Corynebacterium simplex. The same process was used to prepare prednisolone from hydrocortisone .
