Zusammenfassung:	PURPOSE:To obtain a base for solid drug reparation, capable of freely controlling the release of the drug and having both rapid-releasing and slow-releasing activity to a drug, by dissolving a pH-dependent enteric polymer under specific condition in a polyalkylene glycol which is solid at room temperature. CONSTITUTION:The objective base can be produced by dissolving (A) a pH- dependent enteric polymer (e.g. cellulose acetate phthalate) having the following characteristics in (B) a polyalkylene glycol (e.g. polyethylene glycol) which is solid at room temperature, preferably at
