  • Publication number: 20220125745
    Abstract: The present invention relates to a pharmaceutical composition for administration in combination with a drug that causes acidosis. Acidosis occurs due to disrupted acid-base balance caused in a case where a large amount of acid is produced and accumulated in the body. There are many cases where acidosis occurs as a side effect associated with drugs for treating various diseases, which poses problems. The pharmaceutical composition of the present invention not only allows the intended purpose, for which a drug that causes acidosis is administered, to be maintained but also has a remarkable effect in decreasing the concentration of acid accumulated in an organism due to administration of the drug that causes acidosis. Thus, the pharmaceutical composition is expected to be widely used in the fields of medicine and health.
