objective(s): nanoparticles (nps) are known for their specific accumulation in the inflamed tissues of the colon and thus allow a selective delivery to the site of inflammation with minimum adverse effects. the main objective of this work is to attain mesalamine loaded chitosan nanoparticles as a carrier for oral delivery. methods: in this study, mesalamine loaded chitosan nanoparticles were pr...
The main objective of the present study was to formulate gastroretentive effervescent sustained release drug delivery systems of risperidone floating tablets with the help of Methocel® K15, Ethocel® standard 7FP premium, Eudragit ® RS100 sustained release polymers to improve its safety profile, bioavailability and patient compliance. Risperidone floating tablets were formulated by wet granulati...
Eyes and the vision system allow the human being to receive information from the environment to the extent that 90% of the man’s information is acquired through observation, thus health and correct function of this organ have always been important. Diseases threatening vision such as Acute Macular Degeneration and Diabetic Retinopathy deprive millions of people of seeing every year while acce...
objective(s):the aim of this study was to prepare electrospun nanofibers of celecoxib using combination of time-dependent polymers with pectin to achieve a colon-specific drug delivery system for celecoxib. materials and methods:formulations were produced based on two multilevel 22 full factorial designs. the independent variables were the ratio of drug:time-dependent polymer (x1) and the amoun...
this review presents a brief outline of our current knowledge of the structure and chemical composition of the outer membrane vesicles (omvs), originating from the surface of gram negative bacteria including their outer membrane proteins and lipopolysaccharides. moreover, the functional roles and applications of omvs in medical research such as omv-based vaccines, omv adjuvants properties, omv ...
objective(s): in this research, zeolite x and zeolite y were used as vehicle to prepare intestine targeted oral delivery systems of indomethacin and ibuprofen. materials and methods: a soaking procedure was implemented to encapsulate indomethacin or ibuprofen within synthetic zeolites. gravimetric methods and ir spectra of prepared formulations were used to assess drug loading efficiencies into...
hydrogel based metronidazole bioadhesive tablet (hmbt) was prepared as a novel vaginal delivery system to achieve controlled release of drug from the tablet for vaginal candidiasis. the highly swollen hydrogel were prepared by dissolving chitosan in acetic acid solution containing drug, followed by neutralisation with sodium hydroxide and characterized by sem, dsc and ft-ir and evaluated for % ...
