Selected methods of pharmaceutical technology

The subject enables students interested in the employment in pharmaceutical industry to get more profound theoretical and practical knowledge in the field of some of the specialized manufacturing and control procedures of pharmaceutical technology. The methods included in the subject are related to the evaluation of incoming raw materials, preparation of intermediate products, or manufacture of final medicinal preparations and their evaluation. The orientation of the subject links up with other subjects enabling specialization of students for pharmaceutical technology.
