| 摘要 |
<p>The invention concerns a method for making particles containing at least an active principle, said particles being formed by an assembly of molecular complexes each consisting of a molecule of active principle inserted in a host molecule. The method is characterised in that it comprises steps which consist in: placing in a pressurised chamber (1) at least an active principle and a host molecule powder, or a mixture thereof; introducing in said chamber (1) a fluid, consisting of a liquefied gas or a fluid at supercritical pressure, for a time interval sufficient for diffusing the active principle within the powder of the host molecule and for forming an active principle/host molecule complex, and in recovering the powder consisting of the active principle/host molecule complex.</p> |
