Abstract

The invention belongs to the technical field of medicines, and specifically relates to prasugrel hydrobromide tablets and a preparation method thereof. The tablets and the preparation method are characterized in that: raw materials are pretreated or not pretreated before the preparation of the tablets, such that the raw materials contain a certain amount of an organic solvent; other auxiliary materials are added to the raw materials; and the materials are pressed into tablets, such that the prasugrel hydrobromide tablets are prepared. With the prasugrel hydrobromide tablets provided by the invention, the medicine stability is substantially improved, the dissolution rate and the bioavailability are good, and the adverse reaction of the medicine is reduced.
