Studies on intestinal absorption of sulpiride (1): carrier-mediated uptake of sulpiride in the human intestinal cell line Caco-2.
We investigated whether the uptake of a specific antipsychotic agent, sulpiride, in Caco-2 cells is mediated by a carrier-mediated system. Caco-2 cell monolayers were cultured in plastic culture dishes and uptake and efflux studies were conducted. The determination of sulpiride was performed by HPLC. At 37 degrees C, sulpiride uptake in pH 6.0 was twice as much as in pH 7.4. At 4 degrees C, how...
متن کاملStudies on intestinal absorption of sulpiride (3): intestinal absorption of sulpiride in rats.
The aim of this study was to investigate whether the concomitant administration of the substrates or inhibitors of PEPT1, OCTN1, OCTN2, and P-glycoprotein affects the intestinal absorption of sulpiride in rats. The absorption of sulpiride from rat intestine was decreased by the substrates or inhibitors of PEPT1, OCTN1, and OCTN2. On the other hand, the absorption was increased by the substrates...
متن کاملTransepithelial transport of ambroxol hydrochloride across human intestinal Caco-2 cell monolayers.
This study aimed i) to characterize the transepithelial transport of the mucolytic agent ambroxol hydrochloride across the intestinal barrier, ii) to classify the ambroxol according to Biopharmaceutics Classification System (BCS) and iii) to predict ambroxol absorption in humans. Transport of ambroxol (100, 300 and 1000 micromol/l) was studied in a human colon carcinoma cell line Caco-2 in apic...
متن کاملTransport mechanisms of nicotine across the human intestinal epithelial cell line Caco-2.
Ulcerative colitis is a disease more commonly seen in nonsmokers. Because nicotine was postulated to be a beneficial component of tobacco smoke for ulcerative colitis, various formulations of nicotine have been developed to improve the local bioavailability within the gastrointestinal tissue. In the present study, to characterize the disposition of nicotine in the intestines, we investigated in...
متن کاملTransepithelial Transport of the in Human Intestinal Caco - 2 CellBioactive Tripeptide , Monolayers Val - Pro - Pro , Makoto
these tripeptides was studied by using monolayercultured human intestinaJ Caco-2 cells which express rnany enterocyte-Iike functions including the peptide transporter(PepTl)-mediated transport system. ValPro-Pro, an ACE-inhibitors peptide from fermented milk, was used as a model tripeptide. A significant amount of intact Val-Pro-Pro was transported across the Caco-2 cel) monolayer. This transpo...
