OBJECT The surfactant, poloxamer 188 (P-188), has been found to protect against tissue injury in various experimental models. Its protective mechanism may involve the effects of the surfactant against oxidative stress and inflammation. The authors investigated the role of P- 188 in the reduction of tissue injury and macrophage response in a model of excitotoxic brain injury in the rat striatum....

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...

The purpose of this study was to determine the expression of miR-127 and analyze its prognostic and biological significance in breast cancer (BC). A quantitative reverse transcription PCR assay was performed to detect the expression of miR-127 in 15 pairs of BC and corresponding noncancerous tissues. The expression of miR-127 was detected in another 110 BC tissues and its correlations with clin...

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 main objective of this study is to formulate Bromfenac Microemulsion with prolonged duration of action which will help in increasing its topical bioavailability. Bromfenac belongs to the category of NSAID. A calibration curve of Bromfenac was taken in USP Phosphate buffer pH 7.4 at 268nm. Oleic acid, Poloxamer 188 and Propylene glycol were found to have maximum absorbance during solubility ...

OBJECTIVE To develop a biodegradable, modified-release antibiotic pellet capable of eradicating biofilms as a potential novel treatment for biofilm infections. DESIGN Pellets containing poly(DL-lactic-co-glycolic acid) microparticles, rifampin and clindamycin hydrochloride (3.5%, 7%, or 28% antibiotic by weight), and carrier gel (carboxymethylcellulose or poloxamer 407) were tested in vitro. ...

The aim of this study was to fabricate valsartan composite nanoparticles by using the supercritical antisolvent (SAS) process, and to evaluate the correlation between in vitro dissolution and in vivo pharmacokinetic parameters for the poorly water-soluble drug valsartan. Spherical composite nanoparticles with a mean size smaller than 400 nm, which contained valsartan, were successfully fabricat...

DNA-complexes with platelet-like, cationically modified lipid nanoparticles (cLNPs) are studied with regard to the formation of nanocomposite structures with a sandwich-like arrangement of the DNA and platelets. For this purpose suspensions of platelet-like triglyceride nanocrystals, stabilized by a mixture of two nonionic (lecithin plus polysorbate 80 or poloxamer 188) and one cationic stabili...

BACKGROUND Antiretroviral drug discovery and formulation design will facilitate viral clearance in infectious reservoirs. Although progress has been realized for selected hydrophobic integrase and nonnucleoside reverse transcriptase inhibitors, limited success has been seen to date with hydrophilic nucleosides. To overcome these limitations, hydrophobic long-acting drug nanoparticles were creat...
