The invention discloses a controlled-release preparation of a compound medicine containing furotriptan succinate and aspirin, and also discloses a preparation method of the controlled-release preparation of a compound medicine containing furotriptan succinate and aspirin. Compared with the prior art, the controlled-release preparation of the compound medicine of the present invention can release the medicine slowly and at a constant rate in a prescribed release medium, effectively improving the release degree and bioavailability of the controlled-release preparation of the compound medicine, and can be used when taking the medicine. Rapid release in the early stage produces efficacy, and in the later stage, it is released slowly and at a constant rate, maintaining normal blood drug concentration, maintaining drug efficacy for a long time without producing toxic and side effects, without causing drug accumulation and poisoning, improving efficacy, safety and rapidity. Meanwhile, the preparation method in the method of the present invention is suitable for scaled-up production. |
