English to Spanish Medical Medical: Pharmaceuticals Brochure for patients

Text:
"This drug comes as a tablet, granules (mini-tablets), or liquid that is taken by mouth"
Context: brochure for patients
Target language: US Spanish
My translation: "gránulos"
Client's question:
"The European Pharmacopoeia distinguishes between pilules (gránulos) and granules (granulados). Could you confirm that gránulos is ok for “granules” in U.S. Spanish?"

My question for Proz:
In this context, which is the right translation according to the USA Pharmacopoeia: gránulos or granulado?
