Itraconazole nanosuspension for oral delivery: Formulation, characterization and in vitro comparison with marketed formulation

BACKGROUND AND THE PURPOSE OF THE STUDY Itraconazole is a poorly water soluble drug which results in its insufficient bioavailability. The purpose of the present study was to formulate Itraconazole in a nanosuspension to increase the aqueous solubility and to improve its formulation related parameters, dissolution and hence oral bioavailability. METHODS Itraconazole nanosuspension was prepare...

Cyclosporine A-Nanosuspension: Formulation, Characterization and In Vivo Comparison with a Marketed Formulation

Cyclosporine A-nanosuspensions were prepared using zirconium oxide beads as a milling media, Poloxamer 407 as a stabilizer and distilled water as an aqueous medium using the Pearl Milling technique. The optimized formulation was characterized in terms of particle size distribution, surface morphology, drug-surfactant interaction, drug content, saturation solubility, osmolarity, and stability. T...

Enhanced Antihypertensive Activity of Candesartan Cilexetil Nanosuspension: Formulation, Characterization and Pharmacodynamic Study

The objective of the present investigation was to enhance the oral bioavailability of practically insoluble Candesartan cilexetil [CC] by preparing nanosuspension. The nanosuspension was prepared by media milling using zirconium oxide beads and converted to solid state by spray drying. The spray dried nanosuspension of CC [SDCN] was evaluated for particle size, zeta potential, saturation solubi...

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
