PRODUCTION OF BICARBONATE-CONTAINING MEDICINAL LIQUID PREPARATION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a bicarbonate-containing medicinal liquid preparation efficiently containing a prescribed amount of a bicarbonate without dispersion. SOLUTION: This method for producing a bicarbonate-containing medicinal liquid preparation comprises introducing carbon dioxide-containing gas into a preparing tank space part so that carbonic acid in a residual medicinal liquid and carbon dioxide in the preparing tank space part maintain an equilibrium relationship and continuously introducing the carbon dioxide-containing gas into the preparing tank while continuously packing the medicinal liquid in the tank into a vessel during the introduction into the tank space part, in the preparing tank in which the medicinal liquid is decreased by being packed into the vessel during production process of the bicarbonate-containing medicinal liquid preparation.
