frequent dosing of the potent anti-androgen, flutamide, is necessary to reach a therapeutic level for the treatment of prostatic carcinoma. sustained delivery of the drug could reduce the adverse effects such as gastrointestinal disorders and improve patient compliance. in the present study sustained-release matrix tablets of flutamide were prepared by direct compression method using different ...

the aim of this investigation was to design and develop nanoemulsions (nes) as novel ophthalmic delivery systems for brinzolamide (bzd). phase behavior of quaternary systems composed of triacetin and capryoltm 90 (selected oils, screened through the solubility studies), various surfactants (namely, cremophor rh 40, brij 35, labrasol and tyloxapol), transcutol p (as co-surfactant) and water a...

the objective of the present study was to develop floating microspheres of cefpodoxime proxetil in order to achieve an extended retention in the upper git, which may result in enhanced absorption and thereby improved bioavailability. the microspheres were prepared by non-aqueous solvent evaporation method using polymers such as hydroxyl propyl methyl cellulose (hpmc k 15 m), ethyl cellulose in ...

this study examines the controlled release behavior of both water-soluble (acetaminophen, caffeine, theophylline and salicylic acid) and water insoluble (indomethacin) drugs derived from caesalpinia pulcherrima seed gum isolated from caesalpinia pulcherrima kernel powder. it further investigates the effect of incorporating diluents such as microcrystalline cellulose and lactose on caffeine rele...

The present work was aimed to develop and characterize rosuvastatin loaded self emulsifying drug delivery system for the effective management of hypolipidemia (RSEDDS) for improving bioavailability, to enhance solubility, to prolong residence time and to provide sufficient amount of drug to a target site in a sustained release manner. Self-emulsifying drug delivery system was prepared by simple...

Abstract Purpose: our goal is to reduce the release rate of methotrexate (MTX) and increase cell death efficiency. Methods: Carboxylated multi-walled carbon nanotubes (MWCNT-COOH) were functionalized with MTX as a cytotoxic agent, FA as a targeting moiety and polyethylene amine (PEI) as a hydrophilic agent. Ultimately, MWCNT-MTX and MWCNT-MTX-PEI-FA were synthesized. Methotrexate re...
