Pharmaceutical Sciences is a dynamic and interdisciplinary field that aims to integrate fundamental principles of physical and organic chemistry, engineering, biochemistry, and biology to understand how to optimize delivery of drugs to the body and translate this integrated understanding into new and improved therapies against human disease. Drug Discovery and Design deals with the design and synthesis of new drug molecules. This category includes specialized fields of study such as medicinal chemistry, combinatorial chemistry, structural biology, identification of biological targets, and assay development to test drug candidates.

Drug Delivery is concerned with the design of dosage forms — such as tablets, injections or patches — that will deliver the drug to the site of action in a patient. The purpose is to ensure that the drug arrives in the right concentration and at the right time. Specialty fields within Drug Delivery include pharmaceutics, biomaterials, and pharmacokinetics.Pharmaceutical science is the study of the formulation, development and manufacture of new drugs. ... Pharmaceutical science encompasses chemistry, biochemistry, pharmacology, toxicology and physiology. It looks at how different drugs act on the human body and how their healing effects can be safely used.The skills that pharmaceutical scientists acquire aren't only relevant in the pharmaceutical and medical sectors. They are just as useful the food, agriculture, chemical, or cosmetics industries. Some of these career paths require a PhD, but not all of them. Many can be pursued with a Bachelor's degree only.
