The discipline that focuses on the quality aspects of medicines and aims to assure fitness for purpose of medicinal products is Pharmaceutical chemistry. It is the study of drugs, and also involves its development in various stages such as drug discovery, delivery, absorption, metabolism, and more. Pharmaceutical chemistry usually has its work in a lab which has elements of medical analysis, pharmacology, pharmacokinetics, and pharmacodynamics. It is the chemistry which involves cures and remedies for disease, analytical techniques, pharmacology, metabolism, quality assurance, and drug chemistry. The development of this field will enable us to contribute to life-saving remedies and enhance the speed of delivery of new medications. The other branches of study that are important for understanding the effects that drugs have on the body are pharmacokinetics, pharmacodynamics and drug metabolism.
