Effect of the non-ionic surfactant Poloxamer 188 on passive permeability of poorly soluble drugs across Caco-2 cell monolayers.
Drug permeability of the model drugs ketoprofen and nadolol across Caco-2 cell monolayers was determined in the absence and presence of the non-ionic surfactant Poloxamer 188 (Pluronic® F68, P-188). Stringent controls confirmed that P-188 in concentrations up to 50 mg/ml did not adversely affect cell viability or monolayer integrity. Equilibrium experiments confirmed that the drugs were merely ...
متن کاملPredicting apparent passive permeability of Caco-2 and MDCK cell-monolayers: A mechanistic model
Experimentally derived apparent permeabilities, Papp, through cell monolayers such as Caco-2 and MDCK are considered to be an in-vitro gold standard for assessing the uptake efficiency of drugs. Here, we present a mechanistic model that describes 'passive' Papp values (i.e., neglecting active transport) by accounting for the different resistances solutes encounter when permeating a cell monolay...
متن کاملpH-Dependent passive and active transport of acidic drugs across Caco-2 cell monolayers.
The aim of this study was to investigate pH-dependent passive and active transport of acidic drugs across Caco-2 cells. Therefore, the bidirectional pH-dependent transport of two acidic drugs, indomethacin and salicylic acid, across Caco-2 cells was studied in the physiological pH range of the gastrointestinal tract. The transport of both drugs decreased with increased pH, as expected from the ...
متن کاملTransport of hop aroma compounds across Caco-2 monolayers.
Although being reported and used as a sedative remedy for several years, the bioactive principle of hop preparations is still not decisively clarified. Understanding absorption and transformation processes of potential physiologically active constituents is essential to evaluate the likeliness of biological effects on humans. Therefore, single hop aroma compounds as well as digestive transforma...
متن کاملPermeability of Rice Cystatin across Caco-2 Cells
The present work aimed at recovering, purifying, and testing rice cystatin or oryzacystatin I (OCI) bioavailability, to provide scientific evidence that rice cystatin can be used as a functional food ingredient. OCI was extracted from rice bran using 25 mM sodium phosphate buffer containing 0.15 M NaCl at pH 7.0. The resulting homogenate was heat treated, cooled and precipitated with ammonium s...
