written instructions from a physician to a pharmacy for the preparation and issuance of a medicine and also containing directions on how to administer the medicine. Prescriptions are written according to definite forms and rules. A simple prescription is written for a single medicinal substance, and a compound prescription is written for a medicine that consists of two or more ingredients. A prescription is a legal document, since it makes it possible to verify whether a medicine has been prepared correctly.
