The aim of the current study is the evaluation of a recently optimized SEDDS, composed of Solutol HS15 and medium chain glycerides, and self-emulsifying pellets by means of ESR. Tempol-benzoate (TB)-loaded SEDDS were produced and electron spin resonance (ESR) spectroscopy was used to evaluate the diluted self-emulsifying mixtures. Moreover, ESR in vitro(More)
The aim of the current study was the development of a new pellet based self-emulsifying (SE) drug delivery system for the oral delivery of poorly soluble drugs. Furthermore, we wanted to investigate the influence of physiological dilution media and enzymatic digestion on the solubilization capacity of the formulation for the model drug Progesterone.

MRI is a powerful and non-invasive method to follow the fate of oral drug delivery systems in humans. Until now, most MRI studies focused on monolithic dosage forms (tablets and capsules). Small-sized multi-particulate drug delivery systems are very difficult to detect due to the poor differentiation between the delivery system and the food. A new approach(More)
The purpose of the current study is to investigate the feasibility of producing solid self-emulsifying pellets using the extrusion/spheronization technique. Pellets were made from a mixture of C18 partial glycerides, Solutol HS15 and microcrystalline cellulose. Pellets with good physical properties (size, shape, friability) and self-emulsifying properties(More)
