Prazepam (brand name centrax) is a benzodiazepine medication that is used to treat anxiety and insomnia. It works by increasing the activity of a chemical called GABA in the brain, which helps to calm the nervous system. prazepam is a type of long-acting benzodiazepine, which means it stays in the body for a longer period of time compared to some other benzodiazepines.

Like other benzodiazepines, prazepam may cause side effects such as drowsiness, dizziness, and headache. It should be used only under the supervision of a healthcare provider and should not be combined with alcohol or other CNS depressants. People with a history of drug or alcohol abuse should avoid using prazepam as it can be habit-forming.
