Process of preparing aqueous suspension of chloramphenicol palmitate

摘要

An aqueous suspension of chloramphenicol palmitate is prepared by melting chloramphenicol palmitate previously alone, mixing the melt with a hot aqueous solution containing one or more dispersing agents, cooling the dispersion, and then warming the same to prepare a bitterless aqueous suspension containing extremely fine and uniform alpha-type crystals of chloramphenicol palmitate having a high bioactivity.
