Abstract

An aqueous oral liquid pharmaceutical composition system with reduced propensity for agglomeration and phase separation which is particularly amendable to the suspension of one or more pharmaceutical actives that are substantially insoluble in water. The oral liquid pharmaceutical composition may further comprise pharmaceutical actives that are soluble in water and dissolve in the aqueous medium. In the composition of the invention both suspended and any dissolved active agents are distributed homogeneously.
