The concurrent use of herbal medicinals with prescription and over-the-counter drugs carries a risk for unanticipated adverse drug-botanical pharmacokinetic interactions, particularly as a result of cytochrome P450 (P450) inhibition. Extracts of goldenseal (Hydrastis canadensis) containing approximately equal concentrations ( approximately 17 mM) of two(More)
Betulinic acid (BA), a novel natural product with antimelanoma activity, has poor aqueous solubility (<0.1 μg/mL) and therefore exhibits poor bioavailability. The purpose of this study was to explore the feasibility of preparing BA solid dispersions (BA-SDs) with hydrophilic polymers to enhance the aqueous solubility of BA. Melt-quenched solid dispersions(More)
Carbamazepine (CBZ) is a BCS Class II drug with poor solubility profile. In order to improve the physicochemical properties of CBZ, albumin (HSA)-bound CBZ nanoparticles (ABCns) were prepared. Drug-loading studies indicated that monomeric ABCns can be fabricated by self-assembly of anhydrous form III of CBZ and HSA in molar ratios of 1:1 or 2:1 within 0.5 h(More)
Though there are many albumin-based drug delivery systems (ABDDS) in the market, it is not known whether ABDDS can be applied across all chemical classes. In this study, we applied ABDDS to a poorly water-soluble drug betulinic acid (BA) to improve its aqueous solubility. Monomeric albumin-bound BA (ABBns) nanoparticles can be fabricated in the range of(More)
Paracellular route is a natural pathway for the transport of many hydrophilic drugs and macromolecules. The purpose of this study was to prospectively evaluate the ability of novel co-processed non-ionic surfactants to enhance the paracellular permeability of a model hydrophilic drug metformin using Caco-2 (human colonic adenocarcinoma) cell model.
