Pharmaceutical engineering is a branch of pharmaceutical science and technology that involves development and manufacturing of products, processes, and components in the pharmaceuticals industry (i.e. drugs & biologic). While developing pharmaceutical products involves many interrelated disciplines (e.g. medicinal chemists, analytical chemists, clinicians, chemical engineers, biomedical engineers, etc.), the specific sub field of "pharmaceutical engineering" has only emerged recently as a distinct engineering discipline. This now brings the problem-solving principles and quantitative training of engineering to complement the other scientific fields already involved in drug development.
