The developer of a new molecule will get regulatory approval for the medicine and a patent to protect their invention.
Branded or innovative medicines are new medicines. A new medicine comes about through the research and development of a new chemical molecule. They’ll then manufacture and sell it, or give permission for others to do so.
When a company develops a new medicine, the brand name is chosen by the developer and is usually something that’s easy for patients and healthcare professionals to recognise and pronounce, it will start with a capital letter and the generic name will be a more scientific sounding name which won’t start with a capital letter.
