ABSTRACT
Various types of formulations, both aqueous and nonaqueous, have been placed under the rubric of “liquid oral preparations,” including solutions, suspensions, and emulsions. These formulations are primarily employed to enhance the oral bioavailability of a therapeutic, or eliminate the need for a patient to swallow a tablet or capsule. This entry is focused on the applications and limitations of oral solution drug delivery as well as the manufacture and raw materials of the drug product.
