Process for preparing solid lipid sustained release nanoparticles for delivery of vitamins

摘要

The present invention relates to a simple and convenient process for preparing solid lipid sustained release nanoparticles for delivery of drugs/vitamins, preferably fat soluble vitamins and more specifically Vitamin D₃ and retinoic acid (RA). The process involves microemulsion technique. The nanoparticles of Vitamin D₃ and RA obtained by the process of the present invention have utility in treatment of diseases like tuberculosis. Use may be extended to other diseases like AMD, diabetic retinopathy, cancers, hyperpigmentation, acne, and osteoporosis.
