Tranquilizers are a type of medication used to reduce anxiety, agitation, and stress. They work by calming the nervous system, helping individuals feel more relaxed. Commonly prescribed tranquilizers include benzodiazepines like diazepam and lorazepam, which can be effective for short-term relief of anxiety symptoms. These medications can also be used in certain medical procedures to help patients feel more at ease. However, they may cause side effects such as drowsiness or dizziness, and long-term use can lead to dependence. It's important to use tranquilizers under the guidance of a healthcare professional.
