Ann C. Tunstall tells how an idea, a thorough research, and the need to cure a disease lead to the creation of a new drug, which is later on tested for its effects; however, despite the need for the medicine, its creator faces time and money as the main obstacles for development, since a great investment of both elements have to be carried out in order to prove its effectiveness.

As she addresses the need to innovate in this field, she also mentions differences between the development of medical equipment and drugs, stating that though both bear great importance, the first implies fewer difficulties in implementation due to its external use.

In her opinion, an optimum elaboration environment requires scientific knowledge along with plenty resources to conduct tests on the safety and adequacy of medical products. Finally, Tunstall states the importance of the scientific and commercial points of view in this area.
