Etymology

Mifepristone is a made-up drug name that hints at its job: the -pristone part sounds like the hormone 'progesterone', which the drug blocks, and the mi- start can help you remember it is a modified form that changes that hormone's action. So, this name reminds you that mifepristone works by acting against 'progesterone'.
