Embodiment Construction

[0036] A liquid chromatography analysis method for detecting ziprasidone content in blood of the present invention, it comprises the following steps:

[0037] (1) Calibration of standard solution

[0038] (a) Preparation of standard working solution:

[0039]Accurately weigh 10mg of ziprasidone standard substance and place it in a 10mL volumetric flask, dissolve it with 10mL of methanol to obtain standard stock solution A, the concentration of its ziprasidone is 1000ug / mL, and use standard stock solution A with a water content of Dilute with 50% methanol solution, use ziprasidone solutions containing 300, 400, 800, 1600, 3200, 6400 and 12800ng / mL respectively as the standard working solution, and store at -80°C;

[0040] (b) Preparation of internal standard working solution

[0041] Accurately weigh 10 mg of verapamil standard substance in a 10 mL test tube, dissolve with 10 mL of methanol to obtain internal standard stock solution B, whose verapamil concentration is 1000 ug...

Abstract

The invention discloses a liquid chromatographic analysis method for detecting the ziprasidone content in blood. The method includes the following steps of: calibrating a standard solution by using ahigh performance liquid chromatograph and an FLD detector, fitting to obtain a standard curve equation of y=a*x+b, taking a to-be-detected blood sample, and after the to-be-detected blood is processed, detecting the to-be-detected sample by using the high performance liquid chromatograph and the FLD detector similarly to obtain a to-be-detected blood y value, substituting the to-be-detected bloody into the standard curve equation, and calculating the relative concentration x of ziprasidone in the to-be-detected blood sample. Since the concentration of the internal standard working fluid is known, the concentration of ziprasidone drugs in the to-be-detected blood is calculated. According to the scheme of the invention, the serum is subjected to sample injection after liquid-liquid extraction and concentration, the sample is detected by using the FLD detector, and the detection method has low detection limits and high specificity, and is more favorable for monitoring the blood concentration of ziprasidone in the bodies of patients during clinical treatment.

Description

technical field [0001] The invention relates to the technical field of clinical blood drug concentration monitoring of psychotropic drugs, in particular to a method for detecting the concentration of antipsychotic drug ziprasidone in blood. Background technique [0002] Schizophrenia is a clinical syndrome composed of a group of symptoms, and it is a multifactorial disease. Although the current understanding of its etiology is not very clear, the role of individual psychological susceptibility and adverse factors in the external social environment on the occurrence and development of the disease has been recognized by everyone. Both susceptibility quality and external adverse factors may cause the occurrence of the disease through the joint action of internal biological factors, and the pathogenesis factors of different patients may be more important in one aspect. [0003] Ziprasidone is an atypical antipsychotic that is structurally distinct from phenothiazine or butylpht...
