The application relates to the technical field of biological medicine manufacturing, and discloses a controlled-release type preparation composition for realizing ovary function recovery, which comprises a core active unit, a moisturizing slow-release unit and a plant extract component. The core active unit is an anisotropic core-shell structure microcapsule with asymmetric charge distribution, which is composed of chitosan, polyglutamic acid and an internal compound, and a layer of outwardly radiating carboxyl brush-shaped molecular chain is distributed on the surface of the core active unit. The moisturizing slow-release unit comprises a polymer skeleton formed by rosmarinic acid and hyaluronic acid, and the polymer skeleton internally occludes elemene. The application utilizes a kinetic restriction mechanism to construct an anisotropic surface layer topology, avoids mucus protein adsorption, induces anti-inflammatory immune regulation by physically adapting mucosal receptors, the moisturizing slow-release unit firstly constructs a physical barrier to repair damage, and the core active unit is used to realize component graded controlled release.

Providing a controlled-release formulation containing dorotaberine or its salts, or an active substance with a similar tendency to degrade through oxidation / hydrolysis. [Solution] The present invention provides a controlled-release formulation containing dorotaberine or a salt thereof, or an active substance with a similar tendency to degrade through oxidation / hydrolysis. The present invention provides a once- or twice-daily controlled-release formulation of dorotaberine or a salt thereof that avoids fluctuations in plasma levels, reduces pill burden and side effects through a simplified dosing schedule, and consequently improves patient compliance. The present invention also provides a method for preparing a controlled-release formulation of dorotaberine or a salt thereof. The present invention further provides a controlled-release formulation of dorotaberine or a salt thereof for the treatment of at least one symptom of gastrointestinal, biliary, urinary, and gynecological disorders characterized by a spastic state of smooth muscle in a subject.
