The delivery of any medication that is absorbed through the gastrointestinal tract
Capsule
Capsules contain liquid, dry or beaded medication in a soluble casing. For maximum effectiveness, the patient must swallow them whole
Tablet
Tablets comprise medicated powder compressed into a small, solid disc. Typically, tablets may be scored to permit breaking in halves or quarters when lesser dosages are required
Pills
Pills, comprising medicated powder compressed into a small disc, are the same as tablets. in the past, the term pill was used to denote a solid medication taken by mouth. over time, tablet has become the accepted term
Enteric-coated/time-release capsules and tablets
These forms of medication release the drug gradually as layers of the capsule or tablet slowly erode. Time-release capsules or tablets must be swallowed whole
Elixirs
Elixirs are liquid medication combined with alcohol or placed in a sweetened fluid
Emulsions
Emulsions are medications combined with a fat or an oil emulsifier
