The present invention relates to a liposomal pharmaceutical preparation containing a multivalent ionic drug, a process for the preparation of the liposomal pharmaceutical preparation, and a use thereof in the treatment of diseases, in which the liposome has a size of about 30-80 nm, and the phospholipid bilayer has a phospholipid with a Tm higher than body temperature, so that the phase transition temperature of the liposome is higher than the body temperature.

Liposomal pharmaceutical preparation and method for manufacturing the same

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.

Butylphthalide self-emulsifying drug delivery system, its preparation and method and application

The present invention discloses a novel soft capsule of butylphthalide and a process for preparing the same. The soft capsule of butylphthalide is composed of a capsule wall material and a drug-containing oil, wherein the drug-containing oil is essentially composed of butylphthalide and a vegetable oil as the diluent in a weight ratio of about 1:0&#x2dc;10. The capsule wall material is composed of a capsule wall matrix, a plasticizer and water in a weight ratio of 1:0.2&#x2dc;0.4:0.8&#x2dc;1.3. The soft capsule of butylphthalide described in the present invention can mask the strong and special flavor of butylphthalide, and overcome the difficulties associated with formulating oily active ingredient into other oral formulation. The disintegration time of the soft capsule satisfies the requirement of Pharmacopoeia of P.R. China.
