Ramatroban (INN) is a thromboxane receptor antagonist.^[1]

It is also a CRTH2 antagonist.^[2]

It is indicated for the treatment of coronary artery disease.^[3] It has also been used for the treatment of asthma.^[4]

It was developed by the German pharmaceutical company Bayer AG and is co-marketed in Japan by Bayer and Nippon Shinyaku Co. Ltd. under the tradename Baynas.
