1 Dipyridamole enhances digoxin bioavailability via P-glycoprotein inhibition. Dipyridamole ATP binding cassette subfamily B member 1 Homo sapiens
2 BACKGROUND: On the basis of in vitro studies indicating that dipyridamole is an inhibitor for the MDR1 efflux membrane transporter P-glycoprotein, we postulated that dipyridamole could increase the bioavailability of digoxin, a P-glycoprotein substrate. Dipyridamole ATP binding cassette subfamily B member 1 Homo sapiens
3 BACKGROUND: On the basis of in vitro studies indicating that dipyridamole is an inhibitor for the MDR1 efflux membrane transporter P-glycoprotein, we postulated that dipyridamole could increase the bioavailability of digoxin, a P-glycoprotein substrate. Dipyridamole ATP binding cassette subfamily B member 1 Homo sapiens
4 BACKGROUND: On the basis of in vitro studies indicating that dipyridamole is an inhibitor for the MDR1 efflux membrane transporter P-glycoprotein, we postulated that dipyridamole could increase the bioavailability of digoxin, a P-glycoprotein substrate. Dipyridamole ATP binding cassette subfamily B member 1 Homo sapiens
5 BACKGROUND: On the basis of in vitro studies indicating that dipyridamole is an inhibitor for the MDR1 efflux membrane transporter P-glycoprotein, we postulated that dipyridamole could increase the bioavailability of digoxin, a P-glycoprotein substrate. Dipyridamole ATP binding cassette subfamily B member 1 Homo sapiens
6 BACKGROUND: On the basis of in vitro studies indicating that dipyridamole is an inhibitor for the MDR1 efflux membrane transporter P-glycoprotein, we postulated that dipyridamole could increase the bioavailability of digoxin, a P-glycoprotein substrate. Dipyridamole ATP binding cassette subfamily B member 1 Homo sapiens
7 BACKGROUND: On the basis of in vitro studies indicating that dipyridamole is an inhibitor for the MDR1 efflux membrane transporter P-glycoprotein, we postulated that dipyridamole could increase the bioavailability of digoxin, a P-glycoprotein substrate. Dipyridamole ATP binding cassette subfamily B member 1 Homo sapiens
8 MATERIAL AND METHODS: (1) The effect of dipyridamole on in vitro P-glycoprotein-mediated, polarized transport of tritium-labeled digoxin was investigated in Caco-2 cell monolayers. Dipyridamole ATP binding cassette subfamily B member 1 Homo sapiens
9 CONCLUSION: Dipyridamole is an in vitro and in vivo P-glycoprotein inhibitor that increases intestinal digoxin absorption and digoxin plasma concentrations. Dipyridamole ATP binding cassette subfamily B member 1 Homo sapiens
