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...

Poloxamer 407 (P-407) is a copolymer surfactant that induces a dose-controlled dyslipidemia in both mice and rats. Human macrophages cultured with P-407 exhibit a concentration-dependent reduction in cholesterol efflux to apolipoprotein A1 (apoA1) linked to downregulation of the ATP-binding cassette transporter A1 (ABCA1). Activators of peroxisome proliferator-activated receptor gamma (PPARgamm...

Supraphysiological increases in serum triglycerides and cholesterol often occur during pregnancy, but their effects on vascular function are poorly understood. Intraperitoneal injection of the nontoxic surfactant poloxamer 407 (P-407) results in sustained elevation of triglycerides and cholesterol. We asked if P-407-induced hyperlipidemia during late pregnancy adversely affects mesenteric resis...

Poloxamer 407 (P-407) is a copolymer surfactant that induces a dose-controlled dyslipidemia in both mice and rats. Human macrophages cultured with P-407 exhibit a concentration-dependent reduction in cholesterol efflux to apolipoprotein A1 (apoA1) linked to downregulation of the ATP-binding cassette transporter A1 (ABCA1).

In this work, poloxamer (PL)-based binary hydrogels, composed of PL 407 and PL 188, were studied with regard to the physicochemical aspects of sol-gel transition and pharmaceutical formulation issues such as dissolution-release profiles. In particular, we evaluated the cytotoxicity, genotoxicity, and in vivo pharmacological performance of PL 407 and PL 407-PL 188 hydrogels containing tramadol (...

Aim of present study was to screen medicinal plants for flukicidal activity in vitro to develop alternative sources of treatment for trematodes infection. For this purpose, crude methanolic extracts (CME) of Cymbopogn jwarancusa and Conyza canadensis were prepared and live adult flukes viz; Fasciola gigantica, and Paramphistomum cervi isolated from liver and bile ducts of slaughtered buffalo we...

The present study describes the preparation and evaluation of a poloxamer 407 (P407)-based thermoreversible gel using Carbopol 934P (C934P) as a mucoadhesive polymer and hydroxypropyl-β-cyclodextrin (HP-β-CD) for enhancing the aqueous solubility and intranasal absorption of fexofenadine hydrochloride (FXD HCl). The prepared gels were characterized by gelation temperature, viscoelasticity, and d...

Obesity and dyslipidemia are conditions often associated with cardiovascular risk, inflammation, oxidative stress, death. Thus, a new approach has been highlighted to promote research development of pharmacological tools derived from natural sources. Among the most widely studied groups substances, polyphenols such as tyramine stand out. This study investigated hypolipidemic anti-obesity proper...

PURPOSE OF THE STUDY to determine the efficacy, adverse effects and safety of a new Iranian generic product of deferasirox (Osveral®) in Iranian transfusion dependent major thalassemic (TD-MT) patients. METHODS In 9 main thalassemia treatment centers, all of TD-MT patients (aged ≥2 yrs) with serum ferritin (SF) levels≥1000 ng/ml, or >100 ml/kg of RBC transfusion,who could not tolerate parenta...
