The invention relates to a liquid vehicle that can be used to create suspensions and/or solutions of liquid or powdered medications. The vehicle is thixotropic and has improved stability and rheologic characteristics. Vehicles of the invention include an aqueous medium and a suspending agent comprising a polysaccharide having at least 50% glucose repeating saccharide units and at least 90% alpha linkages. The polysaccharide can be a starch, modified starch, or glycogen. The aqueous medium and individual components of the vehicle provide a palatable and easily ingested drug preparation. The invention also provides a vehicle containing an aqueous medium, suspending agent comprising a polysaccharide having at least 50% glucose repeating saccharide units and at least 90% alpha linkages, buffer, and artificial sweetener, the combined suspending vehicle having a pH of about 3 to about 10 and an osmolality of 300 mOmsol or less.
