A aqueous suspension preparations of hardly soluble drugs containing water soluble polymers at a concentration within a range from the concentration at which the decrease in the surface tension of the liquid preparations is initiated to the concentration at which such decrease is terminated. These preparations can be easily redispersed and undergo neither aggregation of the dispersed particles nor caking. The excellent redispersibility of these preparations makes them useful as injections, eye drops, nasal drops, drugs for internal use, lotions, etc.
