During the last few decades, pharmaceutical industry gave more importance to controlled release of dosage forms like solid formulation, semi and topicalpreparation dueto efficacy patient compliance. Normal topical preparations have some disadvantages unpleasant odour, greasiness, skin irritation reported in study cases. Also many topicalpreparations fail reach systemic circulation sufficient am...

Nanotechnology has changed our lives dramatically and influenced every sector of the research, engineering and also business community. Nanotechnology is a rapidly growing science of producing and utilizing nano-sized particles, that measure in nanometer. In other words, nanotechnology is the art of characterizing, manipulating and organizing matter systemically, at the nanometer scale, which h...

nowadays apphcanon of nanotubes in biology and medicinal science is more investigated. nanotubes can passthroueh cell walls and transport and release drugs in special tissues. the purpose of this paper is to investigatethe interaction of a nanotube having hydroxyl functional groups (oh) with an anticancer agent. in this worktransporting of an anticancer drug named 2-(2-amino 6,7-dimethyl pterid...

carvacrol is one of the main components of the eo of some labiatae (laminaceae) members like oregano, thyme and savory. carvacrol has a lot of health benefits for example, antibacterial, and antioxidant activity.we synthesized some silicon derivatives of carvacrol, and characterized them by standard methods. then the monomer of dimethylvinylsilyl carvacrol was synthesized. copolymer of this mon...

patient noncompliance to current tuberculosis (tb) therapy owing to multidrug administration daily leads to treatment failure and emergence of multidrug resistant and extensively drug resistant tb. to avoid the daily dosing, application of nanotechnology is the only viable solution by virtue of sustained release of drugs. other potential advantages of the system include the possibility of selec...

recent advances in nanotechnology have rapidly developed new therapeutic and diagnostic concepts in all aspects of medicine. magnetic nanoparticles (mnps) can be simultaneously functionalized and guided by a magnetic field, thus providing promising tools for several biomedical applications. mnps contrast agents at low concentrations offer the potential to significantly improve existing methods o...

During the past few decades, numerous oral drug delivery systems have been developed to act as drug reservoirs from which the active substance can be released over a specific period of time at a predetermined and controlled rate. It is evident from the recent scientific and patent literatures that an increased interest in novel oral controlled release dosage forms that designed to be retained i...
