  • Patent number: 11938220
    Abstract: Provided is an anesthetic composition for locally administering a local anesthetic agent to a subject in need thereof. The anesthetic composition has a lipid based complex prepared by hydrating a lipid cake containing a local anesthetic agent and a lipid mixture with an aqueous buffer solution at a pH higher than 5.5. Also provided is a method to prepare an anesthetic composition using a simpler and more robust for large-scale manufacture and for providing a high molar ratio of local anesthetic agent to phospholipid content as compared to the prior art. This anesthetic composition has a prolonged duration of efficacy adapted to drug delivery.

  • Publication number: 20230088661
    Abstract: Provided is a liposomal sustained-release composition for use in treatment of pulmonary disease. The liposomal sustained release composition comprises a liposome that includes a polyethylene glycol (PEG)-modified lipid and encapsulates a tyrosine kinase inhibitor. Tyrosine kinase inhibitor is stably entrapped in the liposome, and the resulting liposomal drug formulation can be aerosolized or nebulized for administration via inhalation. This aerosolized liposomal drug formulation yields consistent pharmacokinetic and pharmacodynamic profiles while achieving desired efficacy and safety.

  • Publication number: 20220211623
    Abstract: Provided is a liposomal sustained release composition of bronchodilator for use in treatment of pulmonary disease. The liposomal bronchodilator has a liposome containing a bronchodilator entrapped in the liposome. The bronchodilator has been stably encapsulated in the liposome, and the resulting liposomal bronchodilator is proven to be stably aerosolized or nebulized for administration via the inhalation route to treat a subject in need thereof.

  • Publication number: 20220071934
    Abstract: Provided is a pharmaceutical composition for use in treating postsurgical pain. The pharmaceutical composition comprises a lipid-based complex. The lipid-based complex comprises an amide-type anesthetic and at least one lipid, wherein a molar ratio of the amide-type anesthetic to the at least one lipid of the lipid-based complex is at least 0.5:1. The total amount of the amide-type anesthetic is at least 1.5 to 5 times of a standard therapeutic dose for treating postsurgical pain with the amide-type anesthetic to achieve an improved pain control with desired prolonged analgesic effect.
