The invention provides a dipyridamole emulsion which comprises the following components in parts by weight: 1-2.5 parts of dipyridamole, 5-75 parts of emulsifier, 0.1-15 parts of a co-emulsifier, 25-150 parts of oil, 250-500 parts of water, 0.5-1 part of a sweetening agent, 1-2 parts of an aromatic and 0.25-0.5 part of a preservative. The dipyridamole emulsion provided by the invention has the advantages of uniform texture, good stability, improved drug dissolution, easiness in absorption by the human body and high bioavailability. After high-pressure homogenization, the particle size of the emulsion is small in uniform distribution, the emulsion has good stability, the dissolution of dipyridamole is remarkably improved, and the oral bioavailability is enhanced; and flavoring agents such as the sweetening agent and the aromatic also can be added into the emulsion, so that disagreeable tastes of the drug can be effectively covered, and multiple tastes provide multiple options for children. Through a sterilization process, a little or no preservative can be added, so that the quality of the finished product of the emulsion is improved, and the safety of pediatric drugs is further enhanced.
