Methods for enhancing the release and/or absorption of poorly water soluble active agents are described herein. The method involves dissolving, melting, or suspending a poorly water soluble active agent in one or more molten fatty acids, conjugated fatty acids, (semi-) solid surfactants of high HLB value, and/or hydrophilic polymers. The molten active agent mixture is then suspended and homogenized in a hydrophilic or lipophilic carrier to form microparticles suspended in the hydrophilic or lipophilic carrier. The particles suspended in the hydrophilic or lipophilic carrier can be encapsulated in a hard or soft gelatin or non-gelatin capsule. It is believed that the microparticles produced by the method described above will exhibit enhanced dissolution profiles. In vitro release studies of formulations containing cilostazol and fenofibrate showed 100% dissolution of cilostazol in 15 minutes and over 90% dissolution of fenofibrate in 35 minutes.

La présente invention concerne des procédés pour augmenter la libération et/ou l'absorption d'agents actifs faiblement hydrosolubles. Le procédé met en uvre la dissolution, la fusion ou la suspension d'un agent actif faiblement hydrosoluble dans un ou plusieurs acides gras fondus, acides gras conjugués, tensioactifs (semi-) solides ayant un indice HLB élevé, et/ou polymères hydrophiles. Le mélange d'agent actif fondu est ensuite mis en suspension et homogénéisé dans un véhicule hydrophile ou hydrophobe pour former des microparticules en suspension dans le véhicule hydrophile ou hydrophobe. Les particules en suspension dans le véhicule hydrophile ou hydrophobe peuvent être encapsulées dans une capsule de gélatine molle ou non-gélatine. Il est estimé que les microparticules produites par le procédé décrit ci-dessus présenteront des profils de dissolution améliorés. Des études de libération in vitro de formulations contenant du cilostazol et du fénofibrate indiquent 100 % de dissolution de cilostazol en 15 minutes et plus de 90 % de dissolution de fénofibrate en 35 minutes.
