Method for formulating healthcare products with enhanced stability

摘要

A method is disclosed for formulating healthcare products, including solid pharmaceutical compositions, while avoiding instability caused ba interaction of the active ingredient with excipients. The method comprises the steps of: (a) selecting an active ingredient that loses stability or potency upon interaction with pharmaceutical excipients; and (b) depositing the active ingredient, preferably electrostatically, as a dry powder substantially free of excipients, onto a pharmaceutically acceptable polymer substrate.
