Application

R(+)-Verapamil monohydrochloride hydrate has been used as a P-glycoprotein (gp) inhibitor, to detect P-gp expression on the SK-OV-3 and SK-OV-3/DDP cell surface by flow cytometry. It has also been used as a calcium channel blocker, to evaluate its effect on doxorubicin (DOX) cytotoxicity.

Biochem/physiol Actions

Verapamil is a calcium channel blocker. Verapamil hydrochloride is a phenyl-alkyl amine derivative and is potentially used for treating hypertension, angina pectoris and arrhythmias. It is water soluble in nature.
Inhibitor of P-glycoprotein; less active enantiomer of (±)-verapamil.

The L-isomer of verapamil is a more potent calcium antagonist than the D-isomer. We have examined the two stereoisomers of verapamil for their ability to increase the chemosensitivity in vitro of three drug resistant cell lines (2780AD, MCF7/AdrR and H69LX10).
