Meprobamate
（重定向自Equanil）
Meprobamate — marketed as Miltown by Wallace Laboratories and Equanil by Wyeth, among others — is a carbamate derivative used as an anxiolytic drug. It was the best-selling minor tranquilizer for a time, but has largely been replaced by the benzodiazepines due to their wider therapeutic index (lower risk of toxicity at therapeutically prescribed doses) and lower incidence of serious side effects.
