Medication Summary

Growth hormone may be used to treat short stature associated with Noonan syndrome. A randomized, double-blind, multicenter trial from Japan, by Ozono et al, reported that children with Noonan syndrome–associated short stature can achieve increased height through a 104-week regimen of somatropin administered at doses of 0.033 mg/kg/day or 0.066 mg/kg/day. The report found that the higher dose had a greater effect on height, with the estimated change in the height standard deviation score being 1.47 for the higher dose, compared with 0.84 for the lower dose. The safety profile for both doses was considered favorable. [27]
