  • Publication number: 20210251985
    Abstract: A lurasidone solid dispersion and a preparation method thereof. The solid dispersion includes a mixture of lurasidone, a pharmaceutical carrier and a plasticizer, in which the lurasidone is in a free base form. The lurasidone solid dispersion obtained by the preparation method has characteristics of high dissolution rate (over 30%) in partial neutral medium (such as pH 6.0), significantly increased bioavailability, and significantly reduced food effect, which overcomes the excessive medication limitation in the prior art, avoids the reduction or even inefficiency of the curative effect caused by improper medication of patients, ensures the normal exertion of the medication effect, thereby increases the flexibility and compliance of patients to take medicine.
