Oral administration of different dosage forms is the most commonly used method due to greater flexibility in design of dosage form and high patient acceptance, but the gastrointestinal tract presents several formidable barriers to drug delivery. In oral colon-specific drug delivery system, colon has a large amount of lymphoma tissue (facilitates direct absorption in to the blood), negligible br...
C.G. Wilson and P.J. Crowley (eds.), Controlled Release in Oral Drug Delivery, Advances in Delivery Science and Technology, DOI 10.1007/978-1-4614-1004-1_2, © Controlled Release Society 2011 Abstract Oral drug delivery remains the mainstay of patient treatment although the candidate drugs of the new millennium are becoming increasingly difficult to formulate for good systemic absorption. The ar...
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...
All drug delivery systems, oral drug delivery remain the most preferred option for administration for various drugs. Sustained Release is also providing promising way to decrease the side effect of drug by preventing the fluctuation of the therapeutic concentration of the drug in the body. The basic rationale of sustained drug delivery system optimizes of the biopharmaceutical, pharmacokinetic ...
Mucoadhesive delivery systems offer several advantages over other oral controlled release systems by virtue of prolongation of residence time of drug, its targeting, and localization of the dosage form at a specific site. These advantages include bypass of first pass metabolism of the drug and hence more concentration of the drug is available for absorption. Mucoadhesion occurs between two surf...
Low-oral bioavailability as a consequence of low-water solubility drugs is challenging for formulation scientists in the development new pharmaceutical products. This review aims to highlight relevant considerations when implementing rational strategy lipid-based oral drug delivery systems and discuss shortcomings challenges current classification these such nanoemulsion, Solid lipid nanopartic...
