ABSTRACT
Compared to conventional tablets and capsules, oral liquid dosage forms including solutions, syrups, suspensions, elixirs, or concentrates offer unique advantages to many patients. For example, liquids may provide better patient compliance for those with swallowing difficulties and better dosage control versus a fixed tablet dose. However, there are also a number of ‘‘challenges’’ surrounding the formulation and development of these forms. This chapter presents a brief description of some of the typical areas of challenges and opportunities for liquid formulations, the market justification for overcoming these challenges, and some of the typical excipients used to develop solutions, syrups, and suspensions.
