Buffer components also can be beneficial as counterions in stabilization of tiny-molecule drug products. The weak acid or weak base parts that make up a buffer can act as counterions to develop salt formulations for drug molecules that them selves behave as weak acids or bases in aqueous solutions. The use of a weak acid or foundation for a counterion for drug molecules is often called saltification.
