The invention relates to a split type suppository as well as a preparation method and a use thereof. The split type suppository comprises a suppository body with a groove and an expansion carrier which is mutually separated from the suppository body, wherein the suppository body mainly comprises active ingredients and a matrix; the groove is composed of a groove side wall and a groove bottom; the diameter of the cross section of the groove is 1/3-2/3 that of the cross section of the suppository body; and the length of the groove is 1/5-4/5 the length of the suppository body. The split type suppository provided by the invention not only can avoid the examination and approval of the drug administration agencies, but also can refrain the expansion carrier from adsorbing the active ingredients and the matrix in the suppository body due to splitting of the suppository body and the expansion carrier.
