Abstract
Oral preparations of microcapsules and nanoparticles including an inhibitor of the mammalian target of rapamycin. The preparations are intended to assist with the treatment and prevention of cancer, neurocognitive dysfunction, genetically predisposed disorders, and age-related disorders. The embodiments discussed address the present need for alternative preparations or manufacturing processes that ensure efficacy while improving other performance characteristics such as storage stability, biodistribution, dosage cost, etc.
Claims6
A microparticle pharmaceutical preparation, comprising:
- a) an enteric coating comprising a solid excipient matrix, said solid excipient matrix comprising a polymer composition that remains intact when exposed to acidic conditions of the alimentary canal of an animal and that disintegrates in near-neutral to basic conditions of targeted portions of said alimentary canal, said polymer composition comprising a copolymer of methacrylic acid and methyl methacrylate;
- b) nanoparticles dispersed within said solid excipient matrix, said nanoparticles comprising:
- 1) a micelle-inducing compound, said micelle-inducing compound comprising sodium cholate;
- 2) a pharmaceutically active core comprising rapamycin or an analog of rapamycin;
- c) said micelle-inducing compound naturally inducing formation of micelles, said micelles having properties that promote stability of said rapamycin or said analog of rapamycin when said nanoparticles are dispersed within said solid excipient matrix.
