  • Osteoclast is a multinucleated cell produced by differentiation and fusion of hematopoietic cells and has a bone substrate degradation function. In the bone metabolism, it plays a role of absorbing bone in contrast to osteoblast that newly creates bone. The maintenance of bone mass and morphology depends on the balance of the formation and absorption that the both cells perform, and when osteoclast is activated to promote bone absorption, the balance is broken and reduced bone mass, and morphological destruction and deformation occur.

Abstract

La présente invention concerne une dispersion solide renfermant (i) un médicament, (ii) des excipients, (iii) des plastifiants et (iv) des composés à libération contrôlée de médicaments. Selon cette invention, la solubilité de médicament insoluble ou peu soluble peut être améliorée et une fonction de contrôle de la libération de médicaments peut être fournie simultanément dans un processus d'élaboration unique. Ladite invention a également pour objet une dispersion solide possédant une composition uniforme permettant la libération soutenue de médicaments.
