Impact of fillers on dissolution kinetic of fenofibrate dry foams.

Dry foam technology reveals the opportunity to improve the dissolution behavior of poorly soluble drugs tending to agglomeration due to micronization. In this study, the impact of fillers on the manufacturability, the properties of dry foams and granules as well as the dissolution kinetics of dry foam tablets was investigated using fenofibrate as a model compound. Different maltodextrins and dried glucose syrups, a maltodextrin-phosphatidylcholine complex, isomalt and a 1:1 mixture of mannitol/glucose syrup were used as filler.

Influence of process parameters and equipment on dry foam formulation properties using indomethacin as model drug.

Dry foam technology was developed to overcome insufficient oral bioavailability of poorly soluble and wettable active pharmaceutical ingredients (APIs). It is intended to enable a faster and more efficient dissolution by avoiding API agglomeration and floating of non-wetted API particles. The aim of this study was to investigate the influence of process parameters, such as paste water content and type of equipment used on dry foam morphology, granule characteristics and dissolution behavior of the corresponding tablets using indomethacin as model compound.

Rational formulation development and in vitro assessment of SMEDDS for oral delivery of poorly water soluble drugs.

The aims of this study were to formulate a self-microemulsifying drug delivery system (SMEDDS) by a rational formulation approach using mixture experimental design and to derive general concepts that make the development of such systems more feasible. Various types of oils and surfactants were systematically combined and the phase behaviour upon dilution with simulated gastric fluid examined by construction of phase diagrams. The systems solubilising the highest amount of simulated gastric fluid in the continuous microemulsion area were selected for investigation and optimisation of drug solubility.
