Definition for Sedative
From Biology Forums Dictionary
» Redirected from Tranquilizer
A sedative or tranquilizer is a substance that induces sedation by reducing irritability or excitement.
At higher doses it may result in slurred speech, staggering gait, poor judgment, and slow, uncertain reflexes. Doses of sedatives such as benzodiazepines, when used as a hypnotic to induce sleep, tend to be higher than amounts used to relieve anxiety, whereas only low doses are needed to provide a peaceful effect.
