Abstract
A preparation which can improve the dissolution property of a poorly water soluble drug even when the drug is contained in the preparation at a high content is provided.
When an addition amount of nicotinic acid amide and/or urea is 0.1 to 10% by weight in a solid preparation containing a poorly water soluble drug, and a water-soluble polymer, even a poorly water soluble drug, particularly a drug having a high content can be dissolved out from the preparation by an almost all amount.
