Antimalarials are widely used in African and Southeast Asian countries, where they are combined with other drugs for the treatment of concurrent ailments. The potential for P-glycoprotein (P-gp)-mediated drug-drug interactions (DDIs) between antimalarials and P-gp substrates was examined using a Caco-2 cell-based model. Selected antimalarials were initially screened for their interaction with P...
Multidrug resistance (MDR) is regarded as one of the bottlenecks of successful clinical treatment for numerous chemotherapeutic agents. Multiple key regulators are alleged to be responsible for MDR and making the treatment regimens ineffective. In this review, we discuss MDR in relation to P-glycoprotein (P-gp) and its down-regulation by natural bioactive molecules. P-gp, a unique ATP-dependent...
etoposide, a widely used anticancer drug, exhibits low and variable oral bioavailability mainly because of being substrate for the efflux transporter, p-glycoprotein (p-gp). therefore, the present study was aimed to investigate the effect of d-α-tocopherol polyethylene glycol 1000 succinate (tpgs) and peg 400 as p-gp inhibitors on the intestinal absorption of etoposide. everted sacs of rat smal...

Dexmedetomidine (DEX) a type of the anaesthetic that has been widely used in anaesthesia and intensive care. However, whether DEX affects the pharmacokinetics of drugs remains elusive. As hepatic P‑glycoprotein (P‑gp) serves a critical role in the disposition of drugs, the present study aimed to address whether P‑gp function could be affected by DEX in vitro. In the present study, L02 cells (a ...
The interaction of imatinib mesilate with P-glycoprotein (P-gp) was examined using pig kidney epithelial LLC-PK1 cells versus L-MDR1 cells, which overexpress human P-gp on the apical membrane. The basal-to-apical transport of imatinib mesilate in L-MDR1 cells significantly exceeded that in the parental LLCPK1 cells. The intracellular accumulation of imatinib mesilate after its basal application...
Failure of cancer chemotherapies is often linked to the over expression of ABC efflux transporters like the multidrug resistance P-glycoprotein (P-gp). P-gp expression in cells leads to the elimination of a variety of chemically unrelated, mostly cytotoxic compounds. Administration of chemotherapeutics during therapy frequently selects for cells that over express P-gp and are therefore capable ...
Simultaneous resistance of cancer cells to multiple cytotoxic drugs, multidrug resistance (MDR), is the major limitation to the successful chemotherapeutic treatment of disseminated neoplasms. The 'classical' MDR phenotype is conferred by MDR1/P-glycoprotein (MDR1/P-gp) that is expressed in almost 50% of human cancers. Recent developments in the use of small interfering RNAs for specific inhibi...
CONTEXT In the Randomized Evaluation in PCI Linking Angiomax to Reduced Clinical Events (REPLACE)-2 trial, bivalirudin with provisional glycoprotein IIb/IIIa (Gp IIb/IIIa) inhibition was found to be noninferior to heparin plus planned Gp IIb/IIIa blockade in the prevention of acute ischemic end points and was associated with significantly less bleeding by 30 days after percutaneous coronary int...
