Bromisoval (INN), commonly known as bromovalerylurea, is a hypnotic and sedative of the bromoureide group discovered by Knoll in 1907 and patented in 1909.[1] It is marketed over the counter in Asia under various trade names (such as Brovarin[2]), usually in combination with nonsteroidal anti-inflammatory drugs.

Chronic use of bromisoval has been associated with bromine poisoning.[3][4][5][6]
Bromisoval can be prepared by bromination of isovaleric acid by the Hell-Volhard-Zelinsky reaction followed by reaction with urea.
