Pharmaceutical Sciences
Textbook Exam Questions
Course Introduction
Pharmaceutical Sciences is an interdisciplinary field that encompasses the discovery, development, formulation, delivery, and evaluation of drugs and therapies used in health care. The course covers core topics such as medicinal chemistry, pharmacology, pharmaceutics, pharmacokinetics, and drug regulatory affairs. Students will explore how drugs interact with biological systems, the design and formulation of dosage forms, drug safety and efficacy evaluation, and the regulatory pathways required for bringing new medicines to market. Emphasis is placed on integrating scientific principles with practical applications in drug development and patient care, preparing students for careers in pharmaceutical research, clinical practice, or industry.
