What percentage of ephedrine HCl is exempt from being classified as a dangerous drug?

The classification of ephedrine HCl as a dangerous drug is based on its concentration in a formulation. Specifically, in New Mexico, products containing ephedrine HCl are not considered dangerous drugs if they contain 0.5% or less of the active ingredient. This delineation reflects regulatory consideration of safety and the potential for abuse associated with higher concentrations of ephedrine.

In this context, if a product contains more than 0.5% ephedrine HCl, it would be classified as a dangerous drug, subjecting it to stricter regulatory controls. Therefore, the choice that states ≤0.5% is the limit below which ephedrine HCl is exempt from this classification accurately captures the regulatory threshold. Understanding these limits is crucial for pharmacists to ensure compliance with state law and to provide appropriate counsel regarding drug products containing ephedrine.
