pharm1The especially advanced possibilities of complex pharmaceutical research are exploited at the Faculty of Pharmacy, University of Szeged since its different institutes represent the whole area of pharmaceutical research from the synthesis or isolation of biologically active compounds through their pharmacological or biopharmaceutical investigations to their formulation. Students can join different fields of pharmaceutical research according to their interests, at the same time gain wide-ranging knowledge on other fields as well on the available courses. The scientific parts of each program are introduced separately although they represent a single unit.

Pharmaceutical technology is one of the most dynamically developing fields of pharmaceutical sciences. Its importance lies primarily in the fact that however promising a drug is, it can be used in therapy only in an appropriate form, that is after formulation. Proper formulation is the prerequisite to bioavailability. Thus pharma­ceutical technology is not only a modern, important and interesting applied science but it is also responsible for the success of therapy to a great extent.
There are two basic research directions in modern pharmaceutical technology today:
1. to improve the properties (mainly solubility) of the active ingredient,
2. to plan new drug delivery systems (therapeutic systems) with better bioavailability

Based on this, the doctoral program also consists of two major elements: the improvement of drug properties with solubilization, microencapsulation, molecular encapsulation and spherical crystallization, and the planning of new solid and semi-solid drug delivery systems.

Research programmes
(A) Improvement of the properties of drugs with incorporation in micro- and nanoforms, the planning of new colloidal drug delivery systems

Supervisor: Prof. Tamás Paál CSc

pharm6Courses
The optional courses advertised by the Institute are partly related to the research fields investigated in our Institute (e.g. pharmaceutical rheology, stability of disperse and coherent systems, modern solid and colloidal drug delivery systems), and partly to the main directions of development of pharmaceutical technology (e.g. therapeutic systems). The primary principle in organizing optional courses has been (so far) to enable the students to collect the necessary credit points by the end of the second year so that they can devote all their energy to writing their thesis and publications during the last year.
We took care to provide the student with the possibility to continue his/her student research topic and to make use of the methodology and expertise in approach already acquired, and another consideration was that the work load of the assistant consultants should be uniform, if possible.

Pharmaceutical rheology (I. Erős, E. Csányi, K. Hódi)
A two-semester course, with 15 x 2 hours per semester. The rheological properties of major dosage forms (colloidal solutions, emulsions, suspensions, creams, gels, ointments, powders), modern examinations methods (e.g. creep test, elasticity measurement) and the rheological aspects of important technological operations (mixing, grinding, pressing) are presented in the lectures.

Stability and stabilization of disperse and coherent systems(I. Erős,. P. Szabó-Révész,. K. Hódi, Z. Aigner)
The course lasts for 1 semester, 15 x 3 hours. The most important topics of the lectures are: thermodynamic and kinetic stability, stability of the dispersity degree on and distribution, stability and stabilization of composed preparations, decomposition-selective analytical methods, HPLC, DSC, execution of accelerated stability examinations, determination of expiry.

Relationship between pharmaceutical technology and therapeutic effect(I. Erős,. K. Hódi,. P. Szabó-Révész)
It is a two-semester course, 15 x 3 hours per semester. The following major topics are dealt with during the course: the LADMER system, technological possibilities of prolonged release, technological possibilities of controlled release, technological solutions of targeting drugs, technological solutions of pulsatile release, therapeutic systems for systemic use (infusion systems, transdermal therapeutic systems, oral therapeutic systems, rectal therapeutic systems, implantable pumps), therapeutic systems for local use (ocular therapeutic systems, uterine therapeutic systems), biological computers.
