The Department of Pharmaceutical Sciences was established as a part of the Faculty of Pharmacy by a decision of the Academic Board of MU-Plovdiv from March 2005. Its purpose is to provide students with education in the following disciplines: „Pharmacognosy“, „Pharmaceutical chemistry and analysis“, „Pharmaceutical technology and Biopharmacy“, „Social pharmacy and Pharmaceutical legislation“. The first Department Council was held in March 2008, when Assoc. Prof. Margarita Kassarova, PhD was elected as the first Head of the Department. In 2014, as a result of the increasing number of the academic staff and the heterogeneous profile of the disciplines, the sections Pharmacognosy and Pharmaceutical chemistry were separated from the Department and formed a new structural unit within the Faculty of Pharmacy and in 2024 Section „Social pharmacy and Pharmaceutical legislation“ formed a new Department of Organization and economics of pharmacy.

Currently, the Department of Pharmaceutical Sciences consists of the section Pharmaceutical technology and Biopharmacy with academic staff of 9 people, who take part in the teaching of 6 disciplines.


Academic standarts


Exam syllabus

The Department of Pharmaceutical Sciences takes part in the education of Pharmacy students from the Faculty of Pharmacy and Pharmacy technicians from the Medical College, Medical University-Plovdiv. The academic staff of the Department participate in the teaching of the following disciplines:

  • Pharmaceutical technology – part I;
  • Pharmaceutical technology – part II;
  • Biopharmacy and pharmacokinetics;
  • Pharmaceutical calculations;
  • Technology of medical cosmetics;
  • Drug delivery systems.

For the students’ training in each discipline, the Department has a number of specialized, modernly equipped laboratories – Laboratory for pharmaceutical technology, Laboratory for solid dosage forms, Laboratory for sterile forms, Laboratory for Biopharmacy.
The laboratories are equipped with state-of-the-art equipment for practical exercises and scientific research, which is a prerequisite for generating highly educated and competent specialists in the field of Pharmacy.
The Department is a base for postgraduate training of Master Pharmacists in the specialization „Pharmaceutical Technology and Biopharmacy”.
The Department is a base for training of PhD students in the accredited doctoral program: „Pharmaceutical technology and Biopharmacy”.

The research focus of the Departmentis on improving the effectiveness of drug substances by incorporating them into innovative drug delivery systems. Micro- and nanocarriers technology is an up-to-date approach to overcome the biopharmaceutical limitations of the drugs and the physiological barriers, associated with the administration route and the site of drug absorption.

Phytopreparations are also a field of research in the Section. The influence of technological factors on the extraction of biologically active substances and their incorporation into convenient dosage forms are being studied.

Another research area of the Section is the preparation of semi-solid dosage forms for topical application: hydrogels, organogels, emulgels and bigels with high stability and improved biopharmaceutical properties.

To conduct valuable research, the Department of Pharmaceutical Sciences has three scientific laboratories with state-of-the-art research equipment – Scientific laboratory in Pharmaceutical technology, Laboratory for standardization of phytoproducts at the Technological Center for Emergency Medicine, as well as Laboratory for innovative drug carriers for targeted drug delivery established within the Competence Center PERIMED.

The academic staff of the Department has published in the recent years more than 150 articles in international and national journals, 58 of which have an impact factor. Тhe scientific works have been cited by foreign authors more than 500 times. The results from the research work of the Department have been presented at 219 scientific forums, 72 of which were abroad. The Department has participated in many scientific projects, 3 of which with national funding and 2 with European funding.
