Description: Aims:
To introduce students to the physico-chemical characteristics of drugs and allied entities. To explain how these are relevant to their in vivo actions, their analytical quantification in medicines and biological fluids and in the design of medicinal products.
To introduce students to the concept of dosage forms, brands and generics and orphan drugs.
To introduce students to the ADME processes and the concepts of bioavailability and therapeutic window.
To give the student practical experience of using a variety of analytical instruments to explore selected pharmaceutical applications; to develop data handling and interpretation skills.

Learning Outcomes:
After completing this unit, the student will be able to:
* Have knowledge of what constitutes a medicine, the requirement for different dosage forms and how the production and quality of medicines is regulated.
* Describe the solution properties of drugs and how factors such as thermodynamics, chemical kinetics and pH affect the properties of medicines and their constituent components.
* Describe the factors which influence the release of a drug from its dosage form and its subsequent absorption, distribution, metabolism and elimination from the body and of how pharmacokinetic modelling can be used to optimize drug therapy.
* Explain the role of dosage forms in ensuring drug release and performance and in therapy individualization.
* Explain how the fate and concentration of drugs in the body can be modelled and predicted using basic pharmacokinetic models.
* Use of spectroscopic data in chemical structure elucidation and problem-solving.

Skills:
Scientific and practical skills (T/F/A)
Study skills, handling information, working with others (T/F)
Problem solving (T/F/A).
