Afloqualone is a quinazolinone derivative primarily used as a muscle relaxant and sedative. It acts on the central nervous system to reduce muscle spasms and promote relaxation. Due to its anxiolytic and hypnotic properties, it has been employed in the treatment of anxiety and insomnia, though its use is limited in many countries due to potential for dependence and side effects. It may also be used in veterinary medicine for sedation and muscle relaxation in animals. Its application has declined over time with the development of safer alternatives.
