The Department was established as a part of the Faculty of Pharmacy by a decision of the Academic Board of MU-Plovdiv from March 2005 with the name Department of Pharmaceutical sciences.
Its purpose is to provide students with education in the following disciplines: „Pharmaceutical technology and Biopharmacy“, „Social pharmacy and Pharmaceutical legislation“, „Pharmacognosy“, „Pharmaceutical chemistry and analysis“. 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 of Pharmaceutical sciences 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.
In 2025, the Department of Pharmaceutical Sciences was renamed to Department оf Pharmaceutical Technology аnd Biopharmacy. The academic staff consists of 8 people, who take part in the teaching of 6 disciplines.

Research
The research focus of the Department of Pharmaceutical Technology and Biopharmacy is 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 department. The influence of technological factors on the extraction of biologically active substances and their incorporation into convenient dosage forms are being studied.
In recent years, research has concentrated on several new directions. Various methods are being explored to mask the unpleasant taste of medicinal substances, enhancing their acceptance among specific patient populations. Additionally, models for orodispersible tablets are being developed as a modern innovation in the industry. The encapsulation of essential oils within polymer microstructures to improve their physical stability is also investigated. Developing innovative drug carriers for targeted cancer therapy also represents a promising new direction.
Another research area of the department 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.
The academic staff of the Department of Pharmaceutical Technology and Biopharmacy has published in the recent years more than 150 articles in scientific journals, 50% 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 more than 200 scientific forums. The Department has participated in many scientific projects, 3 of which with national funding and 2 with European funding.
