Something new every day: Defining innovation and innovativeness in drug therapy

The word innovation comes from the Latin noun innovatio, derived from the verb innovare, to introduce [something] new. It can refer either to the act of introducing something new or to the thing itself that is introduced. In terms of commerce, it is defined in the Oxford English Dictionary as the action of introducing a new product into the market; a product newly brought on to the market, a definition that illustrates both aspects of the word meaning. Innovativenessg is the property of being an innovation. Here I identify several different types of innovativeness in drug therapy, including structural, pharmacological or pharmacodynamic, pharmaceutical, and pharmacokinetic innovativeness, and I stress the over-riding importance of clinical innovativeness, which should result in a better benefit to harm balance at an affordable cost.Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins.
