  • Publication number: 20230105701
    Abstract: Provided is a dissolution-enhanced olaparib composition, a preparation method therefor, a use thereof, and a medicament including the dissolution-enhanced olaparib composition. The dissolution-enhanced olaparib composition includes: olaparib; copovidone and a dissolution enhancer, wherein based on 100 parts by weight of olaparib, 100 or more and less than 200 parts by weight of copovidone, and 20 to 150 parts by weight of a dissolution enhancer. The dissolution-enhanced olaparib composition and the medicament prepared therefrom have controllable stability, increased oral absorption of the active ingredient, reduced excipient dosage, improved medication convenience, and are easy for industrial production.

  • Publication number: 20230080811
    Abstract: Provided are a long-acting ropivacaine pharmaceutical composition, a preparation method therefor and use thereof. The pharmaceutical composition comprises: ropivacaine; a pharmaceutical solvent; a pharmaceutical phospholipid; a pharmaceutical oil; and an efficacy enhancer, an optional antioxidant and an optional acid-base regulator. The pharmaceutical composition has a controllable release behavior and a sustained release effect, can significantly reduce the peak plasma concentration of the drug, maintain a stable plasma concentration in the body, prolong the effective treatment time, reduce the effective therapeutic dose, improve the utilization of the drug, and reduce the risk of neurotoxicity. The pharmaceutical composition has a long-acting analgesic effect and can be used for pain treatment.

  • Publication number: 20230054250
    Abstract: A non-aqueous sustained release drug delivery system, which contains, based on the total weight of the sustained release drug delivery system, about 0.1-20% of an active agent, about 0.5-50% of a drug solvent, about 1-98% of a drug sustained release agent, about 0.1-85% of a drug solubilizer, about 0.1-10% of an efficacy enhancer, about 0-1% of an antioxidant, and about 0-8% of an acid-base regulator. The non-aqueous sustained release drug delivery system can yield an improved sustained release effect, improve bioavailability, and enhance the therapeutic effect.
