The purpose of this research was to prepare a floating matrix tablet containing domperidone as a model drug. Polyethylene oxide (PEO) and hydroxypropyl methylcellulose (HPMC) were evaluated for matrix-forming properties. A simplex lattice design was applied to systemically optimize the drug release profile. The amounts of PEO WSR 303, HPMC K15M and sodium bicarbonate were selected as independen...
It is suggested that the brain response of a food odour sensed retro-nasally is related to satiation. The extent of retro-nasal aroma release during consumption depends on the physical structure of a food, i.e. solid foods generate a longer, more pronounced retro-nasal aroma release than liquid foods. The aim of this study was to investigate if a beverage becomes more satiating when the retro-n...
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...

Background and purpose: Pharmaceutical aspects of mucoadhesion have been the subject of great interest during recent years because it provides the possibility of avoiding either destruction by gastrointestinal contents or hepatic first-pass inactivation of drug. In this study, polysaccharide mucilage derived from the seeds of Plantago major L. (Plantaginaceae family) was investigated for use in...
in this study, the effects of various hydrophilic (hpmc and carbopol 971) and plastic (ethylcellulose and eudragit rl100) polymers on the release profile of diltiazem hcl from matrix tablets were evaluated in-vitro. for this purpose, tablets containing 60 mg of diltiazem hcl along with various amounts of the aforementioned polymers were prepared using the wet granulation technique. tablets prep...
an oral suspension could a suitable dosage form for the geriatric patients. the calcium alginate coated ion exchange resinate of propranolol hydrochloride were prepared using amberlite ir-120 by solvent evaporation. microcapsules of propranolol hydrochloride resinate were prepared by solvent evaporation technique,the suspensions were prepared by using deionised water as the vehicle. methyl cell...
