Abstract:
1. A method for improving redispersibility of an aqueous suspension of a hardly soluble drug, comprising: adding a hardly soluble drug to an aqueous medium comprising about 0.1 w/v % to about 10 w/v % polyvinylpyrrolidone and about 0.05 w/v % to about 1.0 w/v % anionic polysaccharide selected from the group consisting of alginic acid and salts thereof, chondroitin sulfate and salts thereof, pectin, and xanthan gum; and mixing the hardly soluble drug with the aqueous medium to form an aqueous suspension of the hardly soluble drug, wherein the suspension exhibits reduced adherence or absorption of the hardly soluble drug to plastic and the hardly soluble drug redisperses into the suspension with agitation.
