Dispensing Pharmacy: This book is written by R M Mehta. You can download it freely in pdf format. Pharmaceutics II is the second course in a two course sequence designed to educate pharmacy students in the various dosage forms used to administer drugs to patients. Pharmaceutics is the discipline of pharmacy that deals with all facets of the process of turning a new chemical entity (NCE) into a medication able to be safely and effectively used by patients in the community. Pharmaceutics is the science of dosage form design. The work of pharmaceutical scientists doesn’t just help relatively healthy people maintain their wellbeing; it gives people with serious illnesses the chance to regain their health. It is, in short, a potentially life-changing career.
