Abstract

The invention discloses a detection method of relevant substances of ibuprofen injection. The relevant substances comprise arginine. A high performance liquid chromatography method is used for detection; the relevant substances are subjected to qualitative or quantitative detection. The detection conditions comprise a detector being an ELSD detector, a chromatographic column being an alkyl silanebonded silica gel column or an amino column, flowing phases including an organic phase and a water phase at the volume ratio of (50 to 70):(50 to 30) (preferably 65:35). By using the method provided by the invention, the relevant substance of the arginine can be accurately monitored; the guarantee is provided for the quality and safety of the ibuprofen injection.

Description

technical field [0001] The invention relates to the field of drug-related substances, in particular to a method for detecting related substances of ibuprofen injection. Background technique [0002] Ibuprofen injection is produced by Cumberland Pharmaceuticals in the United States. It was approved by the FDA in June 2009. Its product name is "CALDOLOR", and it has not entered the Chinese market. People with pain and people with fever. At present, South Korea is in the state of registration, and Australia and Canada are in the state of pre-registration. The prescription is protected by a patent, and the injection is composed of ibuprofen and arginine with a molar ratio of 1:0.92. There are two listed specifications (1) 4ml: 400mg (2) 8ml: 800mg. The usage and dosage in the instructions are intravenous infusion. The dosage should not exceed 3200mg / day. The drug must be diluted before intravenous infusion. Dilute to a final concentration of not more than 4mg / ml. 1. Analg...
