The Montelukast pulsatile delivery system was created with the goal of delivering drug to colon for successful treatment nocturnal asthma. microspheres were sealed within insoluble hard gelatin capsule body an erodible hydrogel plug create a time delayed capsule. Emulsion solvent evaporation used make microspheres. Based on dissolving tests, optimised microsphere formulations designed. entire d...

Physical drug delivery through smart nanocarrier and external stimulus could lead to significant improvements of drug potency as well as noticeable decrease in unwanted side effects. Currently, many external energy sources such as light, magnetic fields, ultrasound, ...,  are under investigation as external stimulus for physical drug delivery. The purpose of this paper is to review most recent ...

Background: Peritoneal metastases (PM) are a common manifestation of gastro-intestinal and gynecological cancers. Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) has been proposed as new drug delivery technique to treat patients with PM. During this procedure, CO2 pneumoperitoneum (12 mmHg) is established. Subsequently, nebulizer (Capnopen®, Zimmern, Germany) aerosolizes the chemothera...

Huperzine A (Hup-A) is a poorly water-soluble drug with low oral bioavailability. A self-microemulsifying drug delivery system (SMEDDS) was used to enhance the oral bioavailability and lymphatic uptake and transport of Hup-A. A single-pass intestinal perfusion (SPIP) technique and a chylomicron flow-blocking approach were used to study its intestinal absorption, mesenteric lymph node distributi...

In this investigation, a new nanocomposite as nanocarrier based on functionalized graphene oxide was synthesized by reaction of tetraethylenepentamine and chlorosulfonic acid with functional groups the surface GO. The characterized FT-IR, XRD TGA, FE-SEM, EDAX, TEM, AFM analysis. To explore potential nanocomposites in drug delivery, loading releases quercetin an anticancer were investigated. re...

The expression of multiple receptors on intestinal epithelial cells enables an actively targeted carrier to significantly enhance the oral delivery of payloads. Conjugating the receptors' ligands on the surfaces of a particulate-delivery system allows site-specific targeting. Here, we used taurocholic acid (TCA) as a ligand for uptake of nanostructured lipid carriers (NLCs) mediated by a bile-a...

Natural products have limitation in the bioavailability of active components because numbers reasons which includes poor solubility ingredient, stability due to gastric and colonic acidity, metabolism by effect gut microflora, absorption across intestinal wall, efflux mechanism first-pass metabolic effects these factors make failure clinical trials efficacy natural phytochemicals used for human...

Context: The use of nanotechnology in medicine and more specifically drug delivery is set to spread rapidly. Currently many substances are under investigation for drug delivery and more specifically for cancer therapy. Evidence Acquisition: Nanodiamonds (NDs) have contributed significantly in the development of highly efficient and successful drug delivery systems, and in stem cell therapy. Dru...

To overcome the problems of gene and drug delivery, nanotechnology has gained interest in recent years. Nanosystems with different compositions and biological properties have been extensively investigated for drug and gene delivery applications. Nanotechnology in drug delivery has been manifested into nanoparticles that can have unique properties both in vitro and in vivo, especially in targete...

BACKGROUND AND AIMS Treatment of inflammatory bowel diseases (IBD) is only aimed to block or inhibit the pathogenetic steps of the inflammatory cascade. Side effects of systemic therapies, poor targeting of orally administered topical drug and low adherence to prescription represent frequent therapeutic challenges. Recent observations suggest that nanotechnology could provide amazing advantage ...
