2026-27 Edition

Pharmaceutical Sciences, B.S.

The Bachelor of Science (B.S.) in Pharmaceutical Sciences is housed in the UC Irvine Department of Pharmaceutical Sciences, a pioneering program designed to train undergraduates in the art of discovering new medicines and deploying them into the clinic. After completing comprehensive background training in basic biology, chemistry, and mathematics, majors continue on to advanced training in organic chemistry, molecular and cellular biology, human genetics and physiology, and biochemistry. Starting in their third year, majors take very deep dives into the topics that define contemporary drug discovery and clinical implementation: medicinal chemistry, molecular pharmacology, and biologics. Supplementing these core areas are a variety of electives and experiential learning opportunities to acquire advanced knowledge in high-throughput experimentation, structure-activity relationship studies, cellular analytics, and cutting-edge OMIC technologies. Most graduates of this program pursue advanced degrees, such as the Ph.D., M.D., or Pharm.D., and pursue careers in biomedical research and professional healthcare, while others seek employment in the public and private sectors after graduation.

Specialization in Medicinal Pharmacology

The specialization in medicinal pharmacology within the B.S. degree provides added flexibility to students who are training for healthcare-related careers, such as medicine, pharmacy, physician associate, and nursing. The specialization can also be used as preparation for research-oriented careers such as drug development. The first three years of the program are similar to the pharmaceutical sciences major and is composed of a foundational study of biology, chemistry, physics, and math. The core of the program begins in the third year and is constructed around courses in molecular pharmacology and pharmacotherapy. These courses provide fundamental instruction in drug mechanisms of action and the clinical use of drugs in the treatment of disease and provide synergistic training in other pharmaceutical sciences courses that can be taken as electives. The program also includes instruction in human anatomy, physiology and microbiology, emphasizing the basic understanding of human health and disease. Students receive instruction in drug development with an accompanying experiential learning in our medicinal chemistry laboratory. Finally, the specialization is designed to provide students with a greater flexibility in scheduling required classes, and they will have access to a large variety of electives allowing them to personalize their educational experience. This specialization allows students to develop a solid preparation for healthcare-focused professional schools or for research-oriented graduate programs.

Undergraduate Honors. Honors at graduation, e.g., cum laude, magna cum laude, summa cum laude, are awarded to approximately the top 16 percent of the graduating seniors. To be eligible for honors, a general criterion is that students must have completed at least 72 units in residence at a University of California campus. For more information, please visit the Latin Honors page.

Students may be admitted to the Pharmaceutical Sciences major upon entering the University as freshmen, via change of major petition, or as transfer students from other colleges and universities.

Information about change-of-major policies is available in the Department of Pharmaceutical Sciences office and at the UC Irvine Change of Major Criteria website.

Transfer Students: All applicants must have completed the following required courses with a grade of B- or better in all courses: one year of general chemistry with laboratory equivalent to UC Irvine's CHEM 1A-CHEM 1B-CHEM 1C and CHEM 1LC-CHEM 1LD AND one year of organic chemistry with laboratory equivalent to UC Irvine’s CHEM 51A-CHEM 51B-CHEM 51C and CHEM 51LB-CHEM 51LC-CHEM 51LD. Transfer students must also complete two years of biology courses equivalent to UC Irvine’s BIO SCI 93, BIO SCI 94, BIO SCI 97. Moreover, all transfer applicants must have a cumulative GPA of 3.0 or better. Additional courses that are recommended, but not required: BIO SCI 98BIO SCI 99. one year of calculus and one year of calculus-based physics.

Pharmaceutical Sciences undergraduate students may remain in the general major or select the Medicinal Pharmacology specialization. The two options differ in their upper-division course requirements listed below, with Medicinal Pharmacology offering courses with a greater focus on the health science professions. To select the specialization, contact the Pharmaceutical Sciences Student Affairs Office.
