PURPOSE The aim of the present investigation was preparation and characterization of sirolimus solid dispersions by solvent evaporation technique to improve its dissolution properties. METHODS Polyvinylpyrrolidone (PVP), Poloxamer 188 and Cremophore RH40 were used to prepare the solid dispersions of sirolimus. In vitro dissolution study using USP type I apparatus, were performed in distilled ...

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...

The main objective of the current study was to formulate poorly water soluble drug Spirinolactone by using solid dispersion technique in order to achieve a better dissolution rate which would further help in enhancing oral bioavailability. Solid dispersions were prepared using two methods; solvent method and fusion method. Solid dispersion was prepared by using polymers, such as Hydroxy propyly...

Fungal infections of skin and/or nails are common diseases resulting in major challenges in topical treatment. Therefore, the objective of the present study was to develop a dermal formulation targeting both tinea pedis and onychomycosis. The antifungal agent ciclopirox olamine (CPX) was incorporated into a variety of poloxamer 407-based formulations and analysed regarding its in vitro permeati...

Ursolic acid is a promising candidate for treatment of Chagas disease; however it has low aqueous solubility and intestinal absorption, which are both limiting factors for bioavailability. Among the strategies to enhance the solubility and dissolution of lipophilic drugs, solid dispersions are growing in popularity. In this study, we employed a mixture of the surfactants poloxamer 407 with sodi...

The objective of the present study was to determine the effect of different ratios of monoolein and oleic acid on in vitro release and skin permeation of tacrolimus from monoolein-based liquid crystalline nanoparticles. The nanoparticles were prepared by sonicating a mixture of melted monoolein, poloxamer 407, oleic acid and tacrolimus to which distilled water was added. Formation of cubosomes ...

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...
