Analeptic

An analeptic, in medicine, is a central nervous system stimulant medication. The term analeptic may also refer specifically to a respiratory analeptic (for example, doxapram), a drug that acts on the central nervous system to stimulate the breathing muscles, improving respiration.

Historically, the term has referred to "a restorative, or remedies proper to restore the body, when wasted or emaciated by disease or hunger."
