Orally administered targeted nanoparticles have a large number of potential biomedical applications and display several putative advantages for oral drug delivery, such as the protection of fragile drugs or modification of drug pharmacokinetics. These advantages notwithstanding, oral drug delivery by nanoparticles remains challenging. The optimization of particle size and surface properties and...

in this work we synthesized nano hydroxyapatite (hap)  by sol-gel method, then we functionalized hydroxyapatite nanoparticle by use of  3-aminopropyl trimethoxysilane (aptms) , to improve the loading and control release of sulfasalazine drug bonded to aptms. the drug release patterns from sulfasalazine loaded hap nanoparticles at ph value 8 for 6h, sulfasalazine loaded functionalized hap nanopa...

Targeted drug delivery systems have been used to deliver drugs in the disease sites of the body. This may reduce potential side effects of drugs and improve their therapeutic effects. Development of brain targeting drug delivery system help in the treatment of disorders related to brain. The most challenging research topic in pharmaceutical sciences is brain targeting drug delivery system. Most...

The clinical outcome of patients with ischemic heart disease can be significantly improved with the implementation of targeted drug delivery into the ischemic myocardium. In this paper, we present our original findings relevant to the problem of therapeutic heart targeting with use of nanoparticles. Experimental approaches included fabrication of carbon and silica nanoparticles, their character...

Inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. The present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (PEC) based microparticles containing antibacterials for the treatment of lung infections.Chitosan polyelectrolyte complex...

Targeted drug delivery to tumor sites is one of the ultimate goals in drug delivery. Recent progress in nanoparticle engineering has certainly improved drug targeting, but the results are not as good as expected. This is largely due to the fact that nanoparticles, regardless of how advanced they are, find the target as a result of blood circulation, like the conventional drug delivery systems d...

Inflammation is a pathologic condition that includes a wide range of diseases namely neurodegenerative diseases. Several natural anti-inflammatory components have been identified in plant extracts used in traditional medicine for the relief of inflammation. Herbal medicine is showing difficulty in crossing the blood-brain barrier (BBB). So that the ability to pass the BBB is the main concern fo...

objective(s): nowadays hydrogels are one of the upcoming classes of polymer-based controlled-release drug delivery systems. temperature and ph-responsive delivery systems have drawn much attention because some diseases reveal themselves by a change in temperature and/or ph. the objective of this work is to prepare and characterize composite membrane using responsive nanoparticles into a polymer...
