Stanovení inhibičního vlivu vybraných cílených protinádorových léčiv na aktivitu ABC lékových efluxních transportérů / The assessment of inhibitory effects of selected targeted anticancer drugs on the activity of ABC drug efflux transportersJurčáková, Júlia January 2021 (has links)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Júlia Jurčáková Supervisor: RNDr. Jakub Hofman PhD. Title of diploma thesis: The assessment of inhibitory effects of selected targeted anticancer drugs on the activity of ABC drug eflux trasporters. Lung cancer is the leading cause of death within oncological diseases. Non-small cell lung carcinoma (NSCLC) accounts for about 85% of all lung cancer, and its major subtypes include adenocarcinoma and squamous cell carcinoma. In addition to surgery, radiotherapy and chemotherapy, the use of targeted low-molecular substances, which target tumor cells with higher specificity, has recently been used in treatment. The two main causes of death in cancer patients are the formation of metastases and the development of multidrug resistance (MDR). This may also be caused by overexpression of the efflux transporters. ATP-binding cassette (ABC) transporters are groups of transmembrane pumps that use energy in the form of ATP to transfer a wide range of substrates. In particular, P-glycoprotein (ABCB1), breast cancer-resistance protein (ABCG2) and multidrug resistance-associated protein 1 (ABCC1) are associated with MDR. Inhibition of these transporters increases the amount of cytostatic substrate within the...

Léčba ischemické choroby dolních končetin / Treatment of lower extremity peripheral artery diseaseJuhász, Jan January 2019 (has links)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology and Toxicology Student: Jan Juhász Supervisor: Prof. MUDr. Radomír Hrdina, CSc. Title of diploma thesis: Treatment of lower extremity peripheral artery disease The lower extremities ischemia is a disease caused most often by atherosclerosis during which the lumen in lower limb arteries becomes narrow. Its prevalence is increasing, especially in the developed countries. The disease can be asymptomatic and symptomatic. The symptoms are very unpleasant and decrease patient's quality of life. Advanced stages of the disease may be life threatening. Therefore, it is vital to timely and correctly diagnose the illness. During the therapy, it is possible to use pharmacological as well as non-pharmacological procedures, and, preferably, a combination of the two types of treatment. The pharmacotherapy can be divided into several parts. The prevention of atherosclerotic complications makes use of preventive measures and antiplatelet therapy to reduce the cardiovascular risk. The symptoms therapy focuses on improving patients' quality of life by prescribing the vasoactive medications cilostazol, naftidrofuryl or pentoxifylin. The critical limb ischemia therapy uses prostaglandin analogues alprostadil, iloprost, limaprost or...

Studium struktury a segmentové dynamiky farmaceutických materiálů na bázi tuhých disperzí léčiv v polymerních matricích pomocí NMR spektroskopie pevného stavu. / Solid-state NMR study of structure and segmental dynamics of pharmaceutical materials based on the solid dispersions of drugs in polymer matrices.Policianová, Olívia January 2014 (has links)
Highly-exact structural characterization is the crucial step in the development and manufacturing process of pharmaceutical materials. Their structural composition is, however, often very complex and hardly identifiable. The eligible way for obtaining definite structural interpretation of these systems appears the high-resolution solid-state nuclear magnetic resonance (ssNMR) spectroscopy. For this purpose the reliable tool - the ssNMR toolbox for comprehensive characterization of various pharmaceutical solids is described. The rigorous optimization of ssNMR techniques is carried out on enormous number of measured samples containing active pharmaceutical ingredients (APIs) with systems ranging from APIs formulated in solid dispersions to pure forms revealing extensive molecular disorder. In this study the influence of polymeric matrix on the creation of solid dispersion type susceptible for finely tuned controlled drug release is likewise discussed. The distinction between variable structural alignments of API molecules in 3D dimension of complicated pharmaceutical solids is allowed via simple strategy - factor analysis applied to hardly describable ssNMR spectra (13 C CP/MAS NMR and 19 F MAS NMR). The results of this ssNMR investigation contribute to better understanding of solid dispersion...

Přechod léčiv s obsahem pseudoefedrinu do skupiny OTC s omezením. / Switching medicines containing pseudoephedrine in OTC group limitedKoníčková, Veronika January 2011 (has links)
Goals: Prepare a case study on the transition to the new OTC medicines groups with restrictions. To evaluate the positives and negatives, which brought the introduction of the group - with OTC restrictions. Pick up generally applicable principles and specify non-functional parts of the system. Method: For data processing method was applied theoretical research. Literature was searched in the database of the Czech National Library - Klementinum, WHO database, TRIBUNE and interfaces of News portals. The instrumental case study was processed for a detailed insight into the issues. The case study is also based on the analysis of the legal framework of the Czech Republic. The documents provided by SÚKL are used for financial analysis. As another method the stakeholder analysis was used - analysis of opinions of people involved in the drug policy. Results: The case study shows that switching medicines containing PSE to the limited group of OTC to prevent producers of drugs buing drugs in Czech pharmacies, but it did not reduce the amount of drugs produced in the country. Producers started to import precursors from abroad. The whole new system established in 2009 was correct in principle, but failed in practice. State Institute for Drug Control or other stakeholders in drug policy have not been able to resolve the ensuing complications.

Řízené uvolňování léčiv z biodegradabilních hydrogelů. / Controlled Drug Release from Biodegradable Hydrogels.Oborná, Jana January 2018 (has links)
This dissertation is focused on the controlled release of drugs from a biodegradable amphiphilic hydrogel based on hydrophobic poly(lactic acid), poly(glycolic acid) and hydrophilic poly(ethylene glycol) (PLGA-PEG-PLGA, ABA) and its modification with itaconic anhydride (ITA). The resulting ,-itaconyl(PLGA-PEG-PLGA) copolymer is referred to as ITA/PLGA-PEG-PLGA/ITA or ITA/ABA/ITA. Itaconic acid provides reactive double bonds and a functional carboxyl group at the ends of the PLGA-PEG-PLGA copolymer chain, thereby rendering the modified ITA/ABA/ITA copolymer less hydrophobic and offering the possibility of forming a carrier for hydrophilic drug substances. These functional copolymers are thermosensitive and change in the external environment (e.g. temperature) causes a sol-gel phase transition due to the formation of micellar structure. The bioactive substances can thus be mixed with a copolymer which is in a low viscous phase (sol phase) and subsequently the mixture can be injected into patient's body at the target site where it forms a gel at 37 °C. This hydrogel becomes a drug depot, which gradually releases the active substance. Prediction of the substance’s release profile from the hydrogel is an effective tool to determine the frequency of administration, potentially enhancing efficacy, and assessment of side effects associated with dosing. The analgesic paracetamol and the sulfonamide antibiotic sulfathiazole were used as model drugs, representing hydrophilic and hydrophobic substances, respectively. The active substances had a significant effect on the resulting hydrogel stiffness. Type of solvent, incubation medium and nanohydroxyapatite also influenced on the gel stiffness and subsequent stability of the hydrogel-drug system. Controlled release of drugs took place in simulated conditions of the human body. Verification of Korsmeyer-Peppas (KP) drug-release model is also discussed in this thesis. The KP model was found suitable for simulating the release of sulfathiazole from ABA and ITA/ABA/ITA hydrogels. On the contrary, the performance of KP model was not suitable for describing the release of paracetamol from the ABA hydrogels. Therefore, a new regression model suitable for both buffered simulated media and water has been proposed. The proposed model fitted better the release of both sulfathiazole and paracetamol from composite material prepared from ABA hydrogel and nanohydroxyapatite.
