Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Chemistry and Pharmaceutical Analysis Candidate: Kristýna Švarcová Consultant: RNDr. Martin Mžik, Ph.D. Supervisor: doc. PharmDr. Radim Kučera, Ph.D. Title: LC-HRMS analysis of selected drugs in biological material II. Anxiety disorders affect up to 25 % of the population in their life, the lifetime prevalence is 13,6 %. Insomnia affect at least one third of the population in their life, the prevalence is 15-40 %. Drugs used to treat anxiety and insomnia easily cross the blood-brain barrier and affect the CNS. It is therefore necessary to determine the correct dosing schedule and monitor treatment. The result is optimization of treatment, reduction of side effects and increased patient adherence to treatment. The rapid qualitative and quantitative analysis for urgent cases of intoxication is also needed. This diploma thesis deals with development and optimization of an extraction method for selected benzodiazepines (alprazolam, bromazepam, diazepam, chlordiazepoxide, clonazepam, midazolam, oxazepam) and zolpidem in human serum. Subsequently, the whole analytical method was validated for use in clinical practice using the UHPLC-HRMS. Protein precipitation with acetonitrile was the most suitable sample preparation...

LC-HRMS analysis of selected drugs in biological material I.
Tomanová, Jana ; Kučera, Radim (advisor) ; Váňová, Nela (referee)
Charles Univesity, Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Chemistry and Pharmaceutical Analysis Candidate: Jana Tomanová Supervisor: doc. PharmDr. Radim Kučera, Ph.D. Consultant: PharmDr. Vít Šesták, Ph.D. Title of the Diploma Thesis: LC-HRMS analysis of selected drugs in biological material I. High performance liquid chromatography is one of the most widespread separation analytical techniques. It is used in various medical, pharmaceutical and industrial laboratories. It uses different affinities of the substances in the analysed mixture to the mobile and stationary phases. Mass spectrometry is one of the instrumental techniques by which charged particles are separated in the gas phase based on the mass- to-charge ratio. Nowadays, great emphasis is placed on the fact that the individual analytical methods which are being developed are subsequently validated according to a guideline issued by national or international authorities. Validation is a process that verifies that a method is suitable for its intended use. In this thesis, the conditions for the determination of warfarin in patient's serum by means of mass spectrometer with LTQ XL linear ion trap were optimized and validated. The optimization of the method was based on the already developed and validated...
