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 & biologics).

While developing pharmaceutical products involves many interrelated disciplines (e.g. medicinal chemists, analytical chemists, clinicians/pharmacologists, pharmacists, chemical engineers, biomedical engineers, etc.), the specific subfield 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.
