State medical board regulation of compounding in physician offices.

 These findings suggest that the incidence of adverse events associated with in-office compounding is low, and that this may be limiting the propensity of state medical and osteopathic boards to implement strict regulations, such as USP compounding standards, that would further restrict such compounding. Therefore, regulatory agencies and legislators would better serve their mission by reallocating resources to ensure the integrity of other aspects of the drug supply chain.
