This bachelor thesis deals with occurrence of pharmaceuticals in aquatic organisms. Sources of pharmaceuticals in recipients are treated effluents from sewage treatment plants. The mostly found in surface water and aquatic organisms are antibiotics, psychoactive pharmaceuticals, antihistamines, painkillers and cardiovascular pharmaceuticals. The occurrence of 20 selected pharmaceuticals at 10 localities affected by treated effluents from sewage treatment plants was studied in several types of matrices, in juvenile fish, plasma and muscle of adult common chub (Squalius cephalus), zebra mussel (Dreissena polymorpha) and benthic organisms. Based on the results, the highest concentrations of pharmaceuticals were found in benthic organisms and zebra mussels. The highest number of pharmaceuticals was found in benthic organisms (18 of 20 analysed) and 3 pharmaceuticals were found at all localities. The lowest number of pharmaceuticals was found in plasma and muscle of adult fish. Bílina Ústí nad Labem and Svratka Židlochovice belong to the most polluted localities. These rivers have low flows and treated wastewater from sewage treatment plants are less diluted therefore the concentration of pharmaceuticals in aquatic organisms is higher.

Drug interactions of cardiovascular drugs and their analysis in the patients of community pharmacy II.
Skořepová, Lenka ; Malý, Josef (advisor) ; Babica, Jan (referee)
Drug interactions of cardiovascular drugs and their analysis in the patients of community pharmacy II. Author: Lenka Skořepová1 Tutor: PharmDr. Josef Malý, Ph.D.1 1 Department of Social and Clinical Pharmacy, Charles university in Prague, Faculty of Pharmacy in Hradec Králové Introduction: Drug interactions are a major cause of toxicity, side effects of drugs and increase the risk of harm to the patient. The pharmacist has an indispensable role in the process of minimizing risks and resolving of drug interactions. Objectives: The aim of the thesis was to carry out a research focused on drug interactions of selected groups of cardiovascular drugs and to describe their management in clinical practice, which could be used during dispensing medicine. Then was evaluated occurrence of these drug interactions in pharmacotherapy of community pharmacy patients. Methods: With the help of selected databases were described individual drug interactions of ACEI and created their management in clinical practice. Sample of patients of community pharmacy was screened for drug interactions. The data were processed by retrospective analysis. For 12 patients with drug interactions were processed case reports and tested solution of drug interactions with using of described management of drug interactions during the...

Drug interactions of cardiovascular drugs and their analysis in the patients of community pharmacy
Vávrová, Zuzana ; Malý, Josef (advisor) ; Matoulková, Petra (referee)
Drug interactions of cardiovascular drugs and their analysis in the patients of community pharmacy Author: Zuzana Vávrová1 Tutor: PharmDr. Josef Malý, Ph.D.1 1 Department of Social and Clinical Pharmacy, Charles University in Prague, Faculty of Pharmacy in Hradec Králové Introduction: Drug interactions represent a serious health problem and they cause many hospitalizations. Although their identification and documentation received a considerable attention, they remain unrecognized for many patients. Objectives: The goal of the thesis was to analyze serious drug interactions between cardiovascular drugs, to describe their management in clinical practice, which is useful during dispensation, and to evaluate occurrence of these drug interaction in a community pharmacy. Methodology: The information was gained from several databases and compared, and afterwards management of major drug interactions of betablockers and calcium channel blockers was created. Patients of a community pharmacy were screened for these drug interactions. The data were processed by frequency analysis. Results: In the theoretical part, 94 drug interactions were analysed. The total number of patients who received betablockers or calcium channel blockers in the community pharmacy was 525. Serious drug interactions described in this...

Occurence of beta-blockers and calcium channel blockers in aquatic environment and their influence on fish
BERANOVÁ, Petra
The aim of this bachelor thesis was to make an overview of distribution of beta-blockers and calcium channel blockers, their occurrence in aquatic environment and their impact on fish. Analysis of data obtained from the website of the State Instiute for Drug Control, which was carried out in Excel revealed, that 53 643 kilograms of beta-blockers and 24 472 kilograms of calcium channel blockers was distributed in the Czech Republic in 2011. Metoprolol, acebutlol and atenolol reached the largem volume of distribution among aktive ingredients in the group of beta-blockers. Verapamil, amlodipin and diltiazem were TOP 3 calcium channel blockers. These drugs are generally the most sold in the world and they can be found in surface waters in the Czech Republic and worldwide at concentrations rating from tens to hundreds ng.l-1 . The reason for this is the low removal rate of beta-blockers and calcium channel blockers in wastewater treatment plants, which ranges from 11 to 76%. Toxicity tests on fish with metoprolol, propranolol, atenolol, verapamil and diltiazem have shown the effect of this pharmaceuticals on e.g., reduction of fecundity, hatchability or heart rate. Various histopatological changes on the liver and heart or malformations of early developmental stages of fis have been also reported. The lowest concentrations of the tested substances at which these effects were observed, ranged mostly from values g.l-1 to mg.l-1, i.e. these concentrations were higher than those commonly found in surface waters. However, some effects were observed also at environmentally relevant concentrations. Due to prolong-term exposure on the organisms beta-blockers and calcium channel blockers may represent a threat to aquatic ecosystems. A solution could be to improve the mechanism for removal of pharmaceuticals in the sewage treatment plants.
