Laboratory Course in Galenical Pharmacy

Abstract

The students gain knowledge on excipients, the preparation of simple dosage forms under consideration of basic quality assurance requirements, on quality control of medicaments and pharmacopoeial requirements. This enables them to analyse and understand simple galenical problems, to study them experimentally, and to evaluate and present the data in a scientific format.

Objective

„Introductory stations“: The students dispose of knowledge on pharmaceutical excipients, preparation methods for simple important dosage forms, and related quality assurance and quality control aspects. With this knowledge, the students are able to prepare simple dosage forms under basic quality assurance measures and to control the galenical quality of the medicaments. The students also possess knowledge on relevant pharmacopoeial requirements and on contents of formularies and excipients handbooks. „Mini project“: The students are able to comprehend and analyse basic galenical problems in their context. The students are also able to use data and information from the literature and other resources to develop a relevant experimental plan for solving experimentally basic galenical problems under consideration of quality assurance issues. The students are finally able to present and evaluate the experiments and data in a scientifically sound oral presentation and written report (publication style).
