It is only licensed for use in Japan and selected Southeast Asian countries. In Japan it is sold under the trade name Irribow.[3][4] and in India as Ibset . 'Elsewhere it is commonly sold under the trade name Nasea and in India as Nozia (150 μg/mL injection & 100 μg oral tablet).[5] While ramosetron itself may relief diarrhea for IBS patients, all the above tablets contain lactose, making them unsuitable for an IBS treatment in most cases.
