Abstract

The invention provides a method for detecting a cyclosporine pharmaceutical preparation, which comprises the following steps of: 1) treating the cyclosporine pharmaceutical preparation with a diluent to obtain a cyclosporine pharmaceutical preparation solution to be detected; and (2) detecting the cyclosporine pharmaceutical preparation solution to be detected obtained in the step (1) through using a gel chromatography exclusion method, wherein a chromatographic column adopted in the gel chromatography exclusion method detection is formed by connecting at least two water-soluble GPC chromatographic columns in series. The method can effectively separate povidone, OP-40 and polyoxyethylene hydrogenated castor oil, has the outstanding advantages of being good in stability, easy and convenient to operate, rapid, high in efficiency, good in sensitivity and the like, can achieve effective separation when the concentration of povidone, OP-40 and polyoxyethylene hydrogenated castor oil is low, and can provide a basis for further research on specific properties of any two or three of povidone, OP-40 and polyoxyethylene hydrogenated castor oil, such as cyclosporin eye drops.

Description

technical field [0001] The invention relates to the field of analysis and detection in medicinal chemistry, in particular, the invention relates to a method for detecting cyclosporine pharmaceutical preparations and auxiliary materials thereof. Background technique [0002] Povidone, polyvinylpyrrolidone (polyvinyl pyrrolidone), referred to as PVP, is a non-ionic polymer compound. As a synthetic water-soluble polymer compound, PVP has film-forming, cohesive, and hygroscopic properties. It also has excellent solubility and physiological compatibility, because it is soluble in both water and most organic solvents, with low toxicity and good physiological compatibility. It is closely related to people's health in medicine, food and cosmetics. favored in the field. In addition, PVP has excellent physiological inertia, does not participate in human metabolism, has excellent biocompatibility, and does not cause any irritation to skin, mucous membranes, eyes, etc. Pharmaceutical-...
