Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Technology Candidate Mgr. Sylva Klovrzová Consultant doc. PharmDr. Zdeňka Šklubalová, Ph.D. Title of Thesis Formulation of propranolol pediatric oral preparations. The theoretical part of this thesis is focused on the specific needs of the pediatric population in relationship to the administration of a medicine, the dosage form and excipients, the use of which should follow guidances of the European Medicines Agency (EMA). Liquid dosage forms, especially oral solutions and suspensions, are described in more detail. Additionally, the requirements on the physical, chemical and microbiological stability are reviewed. In the experimental section we studied the previously published liquid formulations with propranolol hydrochloride obtained from commercial tablets. Their physical stability and pH were observed during a 1-3 month period. No tested formulation complied completely with all the requirements of trials, including optimal composition, stability and palatability of preparations. Three new formulations of suspensions and nine new formulations of solutions of propranolol in a concentration range of 2-8 mg/ml were therefore proposed. The formulations were stabilized with buffering agents and either..
