Norverapamil is primarily used in research settings to study calcium channel activity and its effects on cellular processes. It is often employed as a metabolite of verapamil in pharmacological studies to understand drug metabolism and interactions. Researchers utilize it to investigate its potential role in modulating calcium channels, particularly in cardiovascular and neurological studies. Additionally, Norverapamil is explored for its possible applications in overcoming multidrug resistance in cancer therapy, as it may inhibit drug efflux pumps in certain cancer cells. Its role in these areas makes it a valuable tool for advancing scientific understanding in pharmacology and medicine.
