(R)-Verapamil D7 HCl ((R)-(+)-Verapamil D7 HCl) is a deuterated form of (R)-Verapamil HCl. (R)-Verapamil HCl ((R)-(+)-Verapamil HCl) is a P-Glycoprotein inhibitor. (R)-Verapamil HCl blocks MRP1 mediated transport, resulting in chemosensitization of MRP1-overexpressing cells to anticancer drugs. References: [1]. Plumb JA, et al.
