About this book
- Supports integrated pharmacy eduaction, so that students learn in a professionally relevant contract from day one.
- Focuses on the fundamental ideas that first year students need to fully grasp before progressing with more advanced study.
- Material clearly demonstrates connections between scientific concepts and principles and how they are applied to pharmacy.
- Written by subject experts and edited by academics with a wealth of teaching experience.
Taking medication is a common occurrence for many people, whether it is to soothe an aching head, regulate blood sugars, or to treat life threatening conditions, such as HIV or cancer. In the UK alone, over 900 million prescriptions are dispensed every year. Overseeing all of this are pharmacists: experts in medicines and their use.
The Integrated Foundations of Pharmacy series supports those who are at the beginning of their journey to become a pharmacist. The reader will begin to understand how a drug molecule is made; the process that turns it into a medicine; the role the pharmacist has when dispensing that medicine; and what happens in the body when it is taken. Most importantly, the series shows how each of these aspects are integrated, reflecting the most up-to-date teaching practices.
Pharmaceutics: the science of medicine design explores the different forms that medicines can take, and demonstrates how being able to select the best form - be it a tablet, injectable liquid, or an inhaled gas - requires an understanding of how chemicals behave in different physical states.
