Typically in the pharmaceutical industry, drug products exist in two dosage forms, solid and liquid dosage forms. Included in solid dosage forms are tablets, pellets, pills, beads, spherules, etc. These solid dosage forms are often coated for various reasons, such as odor or taste masking, prevention from moisture, light and/or air, protection from destruction by gastric acid or gastric enzymes, enhanced mechanical strength, aesthetics or controlled release including controlling release sites and/or release rate.
