Corticosteroids decrease bone formation and increase bone resorption both through their effect on calcium regulation (., decreasing absorption and increasing excretion) and inhibition of osteoblast function. This, together with a decrease in the protein matrix of the bone secondary to an increase in protein catabolism , and reduced sex hormone production, may lead to inhibition of bone growth in pediatric patients and the development of osteoporosis at any age. Special consideration should be given to patients at increased risk of osteoporosis (., postmenopausal women) before initiating corticosteroid therapy.
