Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/17646169 | http://adisinsight.springer.com/drugs/800022706 | http://www.drugdevelopment-technology.com/projects/rezular/

Dexverapamil (R-verapamil) is an enantiomer of verapamil. R-isomer behaved as an inhibitor of multidrug-resistant protein MRP1 (involved in the cancer cell multidrug resistance phenotype). It was developed by Knoll (BASF Pharma) as a chemosensitiser and/or modulator of multidrug resistance for use in combination with cancer chemotherapy. Dexverapamil was undergoing phase II clinical studies in France, Italy, Spain, United Kingdom and the US in patients with various cancers. It was also undergoing phase I clinical trials in Japan where it was licensed to Mitsui and Mitsui Toatsu Chemicals. However, development was discontinued. Dexverapamil (R-verapamil) has been developing by AGI therapeutics for the treatment of Irritable bowel syndrome however development was discontinued.

Sample Use Guides

In Vivo Use Guide
Administration of (R)-verapamil may be by any of the conventional routes, for instance oral, intravenous, sublingual, topical and rectal. Conventional formulations may verapamil will be formulated for oral administration. Typically, a suitable dosage of the active component is up to 500 mg per day, but any of the standard dosages for the racemate may be used.
Route of Administration: Other
In Vitro Use Guide
Curator's Comment: in vitro dexverapamil can enhance doxorubicin cytotoxicity in P388/Dx cells with a much greater effect depending on the treatment scheme used, by increasing the intracellular content of drug. https://www.ncbi.nlm.nih.gov/pubmed/9199659/
It was investigated the individual effects of each enantiomer by comparison with the racemic mixture. The cellular effects were tested on both control and human MRP1 cDNA-transfected baby hamster kidney 21 (BHK-21) cells (MRP1-BHK-21). Racemic verapamil was cytotoxic for MRP1-BHK-21 cells at concentrations <10-20 μM, which were ineffective in control BHK-21 cells. The R- and S-enantiomers were highly discriminated because (R)-verapamil did not exhibit any cytotoxicity for the two types of cell, whereas (S)-verapamil displayed a killing activity, even more potent than that observed with the racemic mixture at the same concentration.
