Abstract:
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.
