This study was undertaken to evaluate the biopharmaceutical properties of cyclosporine A (CsA)-loaded nano-matrix particles for inhalation. Nano-matrix particles of CsA with mannitol (nCsAm) were prepared by a flash nano-precipitation technique employing a multi-inlet vortex mixer and evaluated in terms of physicochemical properties, anti-inflammatory(More)
PURPOSE The present study aimed to develop an inhalable self-micellizing solid dispersion of tranilast (SMSD/TL) using poly[MPC-co-BMA] to improve the therapeutic potential and safety. METHODS The safety of poly[MPC-co-BMA] in lungs was assessed using rat lung epithelium-derived L2 cells. SMSD/TL and respirable powder of SMSD/TL (SMSD/TL-RP) were prepared(More)
Meloxicam (MEL) shows a slow onset of action in severe pain patients due to delayed gastric motility. This study aimed to develop an amorphous solid dispersion (ASD) of MEL to achieve rapid oral absorption in severe pain patients. ASD formulations of MEL with hydroxypropylmethylcellulose (ASD-MEL/HPMC) and polyacrylates and polymethacrylates (ASD-MEL/EUD)(More)
The aim of this study is to enhance the antihypothermic action of ginger extract (GE) employing a solid dispersion (SD) approach. The prepared SD of GE (GE/SD) was characterized in terms of physicochemical and pharmacokinetic properties. The antihypothermic action of GE samples was evaluated in a rat model of hypothermia. GE/SD exhibited improved(More)
