Excipient comprising particles of lipids, particles of lipid-like (lipoid) materials or mixtures of said particles, said particles having a diameter of between 10 nm and 10 mum and being solid at room temperature. Said excipient allows, thanks to its solid core, the controlled release of active substances over a longer period, the introduction of hydrophilic drugs into the solid core and a relatively rapid decomposition, this without the formation of toxic secondary products. |
