a. Discussion. Drugs are compounded into various types of preparations
depending upon the physical characteristics of the drugs, the purpose for which
intended, and the method by which they are to be administered. Some drugs are
prepared in more than one form and may therefore be administered in several ways.
b. Solid Preparations.

Capsule. A drug placed in a gelatin container (figures 2-1C and D).

opening and which melts or dissolves at body temperature (figure 2-1B).
