The present study investigates the possibility of using poloxamers as solubility and dissolution rate enhancing agents of poorly water soluble bioactive constituent patchouli alcohol (PA) that can be used for the preparation of immediate release pellets formulation. Two commercially available grades poloxamer 188 (P 188) and poloxamer 407 (P 407) were selected, and solid dispersions (SDs) conta...

Abstract Poloxamer 188 (P188) as a non-ionic surfactant is used in proteinaceous formulations to prevent protein adsorption hydrophobic surfaces and unfolding at interfaces, preventing the formation of aggregates particles. Its chemical intactness crucial stability drug products due its protecting effects interfaces. In order identify mitigate potential risks that might cause degradation P188 d...

The objective of this research was to improve the dissolution of simvastatin and to incorporate it in rapid disintegrating tablets (RDTs) with an optimized disintegration and dissolution characteristics. Polyoxyethylene-polypropylene block copolymer (poloxamer 188) was employed as a hydrophilic carrier to prepare simvastatin solid dispersions (SDs). Fourier transform infrared spectroscopy, diff...

Membrane repair of damaged neurons by surfactant poloxamers has been noted in experimental spinal cord injury and in vitro excitotoxicity. We examined poloxamer-188 (P-188)-mediated neuroprotection in a rat model of glutamate toxicity. Quinolinate was infused into the striatum followed 10 min and 4 h later by P-188 administered either i.v. or intracisternally (i.c.), or by vehicle. Mean neurona...

Objective: In current research, solid lipid nanoparticles (SLN) are formulated for the anticancer drug, nilotinib, to conquer drawbacks associated with drug including low bioavailability and solubility. Methods: The formulation comprised of tripalmitin (lipid), poloxamer 188(surfactant) glyceryl palmitostearate (cosurfactant) by solvent evaporation technique. process variables SLN were optimize...

Poloxamer block copolymers have been studied in multiple applications as drug delivery systems (DDS). These A-B-A amphiphilic block copolymers up-regulate the expression of selected genes in cells and alter genetic responses to antineoplastic agents in cancer. One example is poloxamer 188, also known as pluronic F68, which may be promising as a carrier in DDS. To clarify the possible mechanisti...
