In 2006, the Department of Pharmacology and Drug Toxicology was established as an integral unit of the Faculty of Pharmacy at the Medical University of Plovdiv. The first head of the department was Associate Professor Lyudmil Peychev, MD, PhD.
Habilitated lecturers in drug toxicology and pharmacotherapy were Professor Margarita Karaivanova, MD, DSc, and Associate Professor Yanko Iliev, MD, PhD. Subsequently, the first assistant-professors were appointed: Nina Doncheva, MD (2007), Anita Mihailova, MD (2009), Mihaela Shishmanova-Doseva, PharmD (2009).
Since 2007, Veneta Zhelyazkova (holder of Master degree in Chemistry), has been appointed to the department to manage the majority of the experimental work.
With the increasing volume of teaching responsibilities, the demand for additional staff grew accordingly. Consequently, in 2012, Elisaveta Apostolova PharmD, Mariyan Topolov MD, and Vesela Kokova PharmD were appointed as assistant-professors. From 2015 to 2017, under Article 68 of the Labour Code, Kremena Saracheva PharmD and Liliya Vasileva PharmD served as assistants within the department. In 2017, Kremena Saracheva PharmD was retained as an assistant-professor on permanent contract.
Since 2021, according to a decision of the Faculty Council of the Faculty of Pharmacy, (Protocol No. 2/10.02.2021), subsequently ratified by the Academic Council (Protocol No.2/18.02.2021), the department has been renamed as Department of Pharmacology, Toxicology, and Pharmacotherapy.
In April 2022, Chief Assistant Professor Elisaveta Apostolova was conferred the academic title of “Associate Professor” and since April 2024, she has been the head of the department. Additionally, in January 2024, Chief Assistant Professor Vesela Kokova was also conferred the academic title of “Associate Professor.”
Pursuant to Rector’s Order No.R3651/11.12.2023, Kristina Stavrakeva PharmD has been appointed as a regular PhD student under the supervision of Associate Professor Apostolova.
As of December 2023, Sevdalina Andonova has joined the department as a medical laboratory technician.
Recently, the academic staff of the department consists of 8 lecturers, including 3 habilitated members, 5 Chief Assistants Professors holding PhDs, and 1 PhD candidate.
Faculty members are engaged in the teaching of 6 disciplines: pharmacology (in both Bulgarian and English lenguage), clinical pharmacology (in both Bulgarian and English lenguage), pharmacokinetics, drug toxicology, pharmacotherapy, and clinical homeopathy. Additionally, there is ongoing collaboration with students on scientific projects for the investigation of biologically active substances.

The Department of Pharmacology and Drug Toxicology has been established in 2006 with Head of the Department prof. Ludmil Peychev, MD, PhD, MHM.
Five different disciplines – General Pharmacology, Pharmacokinetics, Drug Toxicology, Pharmacotherapy and Clinical Homeopathy are being taught by the academic staff of the Department.
The pharmacology course is included in the academic program for medicine, dental medicine, pharmacy, nursery, midwifery. Many students participate in the research of biologically active substances under the guidance of their teachers.
Members of the academic staff are engaged in 10 research projects, supported by Medical University-Plovdiv and the Ministry of Education and Science of Bulgaria.

Science & Research
The academic staff of the department conducts research in the following primary scientific domains:
• Research in neuropsychopharmacology,
• Investigation of the analgesic and anti-inflammatory activities of natural and synthetic substances,
• Study of the effects of natural and synthetic substances on learning, memory, and cognitive functions in models of neurodegenerative diseases,
• Experimental research on obesity and prediabetes,
• Evaluation of the potential hepatoprotective effects of natural bioactive substances,
• Exploration of the neuroprotective effects of bioactive substances from natural and synthetic sources,
• Examination of the acute and chronic toxicity of newly synthesized compounds from natural and synthetic origins.
Over the past five years, the department has achieved significant results in the scientific field (Table 1). The academic staff of the department has contributed to the publication of 72 scientific articles, with 41 published in journals with impact factor. Scientific presentations and reports totaled 98 and 45 of them were presented on international forums. The department has collaborated on the writing of 18 textbooks and practical manuals, and 6 monographs. Additionally, 2 habilitations for associate professorship were completed (E. Apostolova and V.
