  • Patent number: 9795585
    Abstract: The inventive subject matter relates to the use of L-butylphthalide in the manufacturing of medicaments for the prevention and treatment of cerebral ischemia-induced disease. Cerebral ischemia of the animals or human induces cerebral infarction, neurological deficit, memory disorder, cerebral edema, cerebral apoplexy, metabolic disorder of energy, changes of cerebral blood flow, and the like. The in vivo experiments show that L-butylphthalide can effectively reduce the above-mentioned adverse symptoms induced by cerebral ischemia.

  • Patent number: 8728518
    Abstract: The present invention relates to a novel drug delivery and release system, i.e. Self-emulsifying Drug Delivery System (SEDDS), of butylphthalide, to a preparation process thereof, and to a use thereof in a pharmaceutical formulation. The drug delivery system comprises as essential ingredients 1% to 65% of butylphthalide and 10% to 65% of a emulsifying agent, together with various excipients as required depending on the desired dosage forms. The present invention significantly increases the contact area between butylphthalide and the mucous membrane of the gastrointestinal tract, and therefore improves the absorptivity of the drug.

  • Patent number: 6583081
    Abstract: Zeolites exchanged with lithium, rubidium, cesium cations and trivalent cations are prepared by first partially, fully or excessively ion-exchanging a sodium-containing zeolite, a potassium-containing zeolite or a sodium- and potassium-containing zeolite with trivalent cations, then calcining the partially, fully or excessively trivalent cation-exchanged zeolite, and then ion exchanging the calcined zeolite with lithium rubidium, cesium cations, thereby replacing hydrogen and any sodium and/or potassium cations remaining in the zeolite with lithium, rubidium, cesium cations, whereby trivalent cations present in the zeolite will not be substantially replaced by the lithium ions.
