Burimamide is an antagonist at the H₂ and H₃ histamine receptors. At physiological pH, it is largely inactive as an H₂ antagonist,^[1] but its H₃ affinity is 100x higher. It is a thiourea derivative.

Burimamide was first developed by scientists at Smith, Kline & French (SK&F; now GlaxoSmithKline) in their intent to develop a histamine antagonist for the treatment of peptic ulcers.^[2] The discovery of burimamide ultimately led to the development of cimetidine (Tagamet).^[2]
