Testing the volume of injection in container is to ensure that the nominal content of a container can be administered to the patient. The method to test the volume of injection in container is described in European Pharmacopeia (EP) and United States Pharmacopeia (USP). However there is no method to test the volume of injection in Korean Pharmacopeia (KP). So we surveyed the method practiced by 53 pharmaceutical companies in Korea by a questionnaire and tested commercially available injections by discharged volume. As the result, we agreed with the International Conference on Harmonization (ICH) test method for discharged volume. It was suggested that the ICH test method for discharged volume of injection in container would be adopted.
