Application of Sequential Design of Experiments to Develop Ibuprofen (400 mg) Tablets by Direct Compression

Abstract

A strategy based on sequential design of experiments (screening, optimization and confirmation) was used to develop a tablet formulation of ibuprofen (400 mg) that is manufactured by direct compression. This formulation has a high content of ibuprofen (76%), in spite of the poor flowability of the drug substance. Sequential design of experiments proved to be an effective and efficient strategy in formulation development.
