Abstract

The invention provides a kit for detecting anti-depressant drugs in serum and plasma by liquid chromatography tandem mass spectrometry. The kit comprises drug standard substances, drug internal standardization compounds, drug extraction compositions, negative plasma and a diluent. The drug standard substances comprise amfebutamone, oxybupropion, citalopram, Escitalopram, venlafaxine, O-desmethylvenlafaxine, duloxetine, fluoxetine, norfloxetine, fluvoxamine, mirtazapine, paroxetine, sertraline and trazodone. The drug internal standardization compounds comprise amfebutamone-d9, oxybupropion-d6,citalopram-d6, venlafaxine-d6, O-desmethylvenlafaxine-d6, duloxetine-d3, fluoxetine-d6, norfloxetine-d6, fluvoxamine-d4, mirtazapine-d3, paroxetine-d6, sertraline-d3 and trazodone-d6. The drug extraction compositions comprise, by volume, 60% of methanol solution, 20% of acetonitrile solution, 10% of isopropyl alcohol solution and 10% of purified water. The diluent comprises 50 % of methanol waterfluid. The kit can be used for simultaneous detection of the anti-depressant drugs and active metabolites, the detection time is short, and flux is high.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a liquid chromatography tandem mass spectrometry kit for detecting antidepressant drugs and its application. The kit is suitable for using tandem mass spectrometry to detect antidepressant drugs and their metabolites. Background technique [0002] Antidepressive drugs refer to a group of psychotropic drugs mainly used to treat mental illness with depression as the prominent symptom. There are two common types of antidepressant drugs: monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants. (TCA) and tetracyclic antidepressants. However, improper use of antidepressants can cause side effects such as drowsiness, dry mouth, blurred vision, constipation, rapid heartbeat, difficulty urinating, and postural hypotension, and may also cause serious cardiovascular side effects, urinary retention, and intestinal paralysis. , severe cases even directly lead to acute poisoning o...
