Abstract
- A single dose of 2.5 mg prednisone leads to a significant transient decrease in serum osteocalcin, which is only demonstrated by frequent serum sampling. The aim of the present study was to evaluate whether a single dose of inhaled beclomethasone dipropionate causes transient changes in serum osteocalcin, indicating a systemic effect on bone cells. In a double-blind, placebo controlled, cross-over design we evaluated the effects of single doses of 250 μg and 1000 μg beclomethasone on the circadian rhythm in serum osteocalcin. Fifteen normal subjects aged 2 3-38 years were studied twice with an interval of one week with hourly blood sampling from 16.30 until 1 7.00 the following day; 1000 μg beclomethasone, but not 250 μg, suppressed serum cortisol by 14.4±6.7% (p=0.03). Neither of the beclomethasone doses significantly altered the time pattern of serum osteocalcin. We conclude that a single inhaled dose of beclomethasone in the therapeutical range does not acutely influence osteoblastic activity as judged from serial measurements of serum osteocalcin.
