    Abstract:
    Inhaled glucocorticoids (IGs) are today the first-line treatment for bronchial asthma. The systemic effects of inhaled glucocorticoids, such as suppressing the hypothalamic-pituitary-adrenal axis, are generally less than those with oral glucocorticoids. However, there is a long-term risk of adverse effects on bone. The objective of this piece was to review the published data on the effects of IGs on bone metabolism markers and bone mineral density in adults and in pediatric patients. The reviewed studies do not provide uniform results. Nevertheless, in general they suggest that IGs can affect metabolism and bone mineral density, especially: 1) when high doses are administered (more than 400 micrograms/day in children and more than 800 micrograms/day in adults), 2) in pediatric patients, in whom growth in stature can also be affected, 3) in patients whose intake of calcium and vitamin D is inadequate, and 4) in postmenopausal women not undergoing hormone replacement therapy. In general, at therapeutically equivalent doses, beclomethasone has a greater deleterious effect on bone than does budesonide, which in turn has more of an effect than does fluticasone. In addition to the obvious precaution of using the lowest effective dose, other proposed preventive measures include: 1) adequate instruction on the use of aerosols, 2) the use of large volume spacer devices, 3) rinsing the mouth after administering IGs, and 4) dietary adjustments or supplements in order to ensure an adequate intake of calcium and vitamin D.
