What is the definition or description of: sedative?

Drugs which Sedate : A sedative is a class of drug which induces sedation. Depending on the dosage and person, these drugs can have an anti-anxiety effect, induce sleep, and even unconsciousness.

Relaxation meds: A sedative is a medication that induces calm, relaxation, and usually, decreases anxiety. Sedatives - especially at higher doses - can induce sleep. The sleep-inducing attribute is more correctly called "hypnotic". Not surprisingly, most medications produce more than one specific effect. Therefore, one sedative may dominate in the reduction of anxiety and another in inducing sleepiness.
