sedative
Meaning: A drug or substance that promotes calm or induces sleep by reducing irritability or excitement.
Sedatives work by depressing the central nervous system and are commonly prescribed for anxiety, insomnia, and before medical procedures. The term can be used as both a noun and an adjective. It is important to distinguish sedatives from anaesthetics: sedatives reduce awareness and anxiety, whereas anaesthetics eliminate sensation entirely.
