- Establishment of UPLC-MS/MS(Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry) analysis method for amphotericin B in plasma. Due to various factors such as small sample size, low drug concentration, endogenous substance interference, and individual differences that affect the determination of in vivo samples, in order to ensure the reliability of the method, it is necessary to validate the method while establishing an in vivo sample analysis method.
By systematically optimizing plasma sample pretreatment, chromatographic conditions, and mass spectrometry conditions, and conducting methodological investigations on specificity, minimum quantification limit, minimum detection limit, linear range, accuracy, precision, matrix effects, stability system, etc., an accurate, rapid, and highly sensitive UPLC-MS/MS method is established.
- Study on the pharmacokinetic characteristics of amphotericin B liposomes in patients with severe invasive fungal infections undergoing plasma exchange therapy using traditional Chinese medicine Research subjects: The research subjects of this project are patients with severe invasive fungal infections receiving plasma exchange therapy. Plan to include 10 people.
When the patient's dosage is stable, collect 4mL of intravenous blood from the EDTA-K2(Ethylenediaminetetraacetic acid dipotassium salt) collection tube within 1 hour before the administration of liposomal amphotericin B before plasma exchange, immediately after infusion, 1 hour, 6 hours, 12 hours after infusion, 5 minutes before and immediately after plasma exchange, immediately after the next infusion after plasma exchange, and 24 hours. Subsequent pharmacokinetic studies will be conducted.
