Meprobamate is a medication that belongs to the class of drugs known as carbamates. It is primarily used as a mild tranquilizer and anxiolytic. Some common synonyms for meprobamate include Miltown, Equanil, and Meprospan. These drugs have similar effects as meprobamate, as they are all central nervous system depressants and work by increasing the activity of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. Meprobamate and its synonyms are often used to treat anxiety disorders and muscle spasms, although they have been known to cause side effects such as drowsiness, dizziness, and impaired coordination. It is important to use these drugs only under medical supervision.
