  • Patent number: 9782343
    Abstract: The embodiments herein provide a nano-carrier system for delivering a long-acting injectable drug of morphine and a method of synthesising the same. The morphine entrapped nanoparticles are prepared using a lipid/phospholipid core which is coated by a polymer. The lipid and phospholipid are dissolved in organic solvent. This solution is transferred into an aqueous phase consisting of distilled water or a buffer. A solution of polymer is added drop wise. The drug entrapped nanoparticle formation is achieved by diffusion of the organic solvent within the aqueous solvent to obtain the nanoparticles. The drug gets entrapped within the nanoparticles via the anti-solvency effect of the aqueous matrix. The resulting drug nanocarriers are capable of releasing the drug in a slow rate upon injection. The synthesized drug carrying nanoparticles are cryopreserved stored for future administration. For better storage, the nanodispersion is dried to form a powder.

  • Patent number: 9370488
    Abstract: The embodiments herein provide a long-acting injectable drug (insulin) delivery nano-carrier system and a method of synthesizing the same. The insulin entrapped nanoparticles are prepared using a lipid/phospholipid core which is coated by a polymer. The lipid and phospholipid are dissolved in organic solvent. This solution is transferred into an aqueous phase consisting of distilled water or a buffer and dissolved insulin. A solution of polymer is added drop wise. The drug entrapped nanoparticle formation is achieved by diffusion of the organic solvent within the aqueous solvent to obtain the nanoparticles. The drug gets entrapped within the formed nanoparticles via the anti-solvency effect of the aqueous matrix. The resulting drug nanocarriers are capable of releasing the drug in a slow rate upon injection. The synthesized drug carrying nanoparticles are cryopreserved stored for future administration. For better storage the nanodispersion is dried to form a powder.
