To pursue an MSc in Pharmacy, you would need to:
* Apply to an MSc Pharmacy program: You will need to meet the specific entry requirements of the program, which will likely include a relevant undergraduate degree (often a Bachelor of Pharmacy, BSc in Pharmaceutical Sciences, or a closely related field). A BSc in Biotechnology might be considered, but you may need to demonstrate additional relevant coursework or experience to compensate for the missing foundational pharmacy knowledge. This may involve taking bridging courses or having significant relevant work experience.
* Meet the prerequisite coursework: Most MSc Pharmacy programs require specific undergraduate courses in chemistry (organic, inorganic, analytical, physical), biology, pharmacology, and potentially others. Your BSc in Biotechnology may have some overlap, but it is unlikely to fulfill all requirements. You might need to take additional courses to satisfy these prerequisites before being considered for admission.
In short, you don't "change" your degree; you apply for a new, different degree. Your BSc in Biotechnology may help you, but it won't automatically qualify you for an MSc in Pharmacy. Contact universities offering the MSc Pharmacy program directly to inquire about their specific entry requirements and see if your background is considered suitable. They will be able to advise you on the best path forward.
