Controlled Release Gel Formulations
Simple gel formulations may be applied to enhance the systemic and local exposure of potential compounds. The aim of this thesis is the development and characterization of controlled release formulations based on thermoreversible poloxamer gels, which are suitable for novel drug delivery applications. In particular co-solvents (DMSO, ethanol), mucoadhesive polymers (chitosan, alginate) and salt...
متن کاملHydroxypropyl Starch Nanoparticles as Controlled Release
Hydroxypropyl starch was synthesized by modified sago starch with hydroxypropylation reaction. Hydroxypropyl starch nanoparticles with mean particle sizes of 110 nm are obtained by controlled precipitation through the drop-wise addition of dissolved hydroxypropyl starch solution into excess absolute ethanol. Piperine was loaded onto hydroxypropyl starch nanoparticles and native starch nanoparti...
متن کاملOptimized fibrin gel bead assay for the study of angiogenesis.
Angiogenesis is a complex multi-step process, where, in response to angiogenic stimuli, new vessels are created from the existing vasculature. These steps include: degradation of the basement membrane, proliferation and migration (sprouting) of endothelial cells (EC) into the extracellular matrix, alignment of EC into cords, branching, lumen formation, anastomosis, and formation of a new baseme...
متن کاملFormulation of Controlled Release Matrix Tablet of Diclofenac Sodium Using Cross Linked Starch Urea
The présent works aims to develop controlled release matrix tablet of diclofenac sodium with modified starch cross linked starch urea as an sustained release polymer and to evaluate the prepared dosage form for physical parameters like weight variation, hardness, friability and drug content. Cross linked starch urea is modified starch introducing desirable alterations in the starch structure so...
متن کاملImpact of controlled release urea on maize yield and nitrogen use efficiency under different water conditions
Controlled release urea (CRU) has been widely adopted to increase nitrogen (N) use efficiency and maize production, but the impacts can range widely depending on water availability in the soil. In an experiment using Zhengdan 958 (a popular summer maize hybrid), three levels of water treatments (adequate water condition [W3], which maintained soil moisture at about 75% ± 5% of the soil's field ...
