Methods and compositions for treating conditions caused by excessive calcium influx in cells using optically pure (-) amlodipine

Methods are disclosed utilizing the optically pure (-) isomer of amlodipine. This compound is a potent drug for the treatment of hypertension while avoiding the concomitant liability of adverse effects associated with the racemic mixture of amlodipine. The (-) isomer of amlodipine is also useful for the treatment of angina and such other conditions as may be related to the activity of (-) amlodipine as a calcium channel antagonist such as cerebral ischemia, cerebral disorders, arrhythmias, cardiac hypertrophy, coronary vasospasm, myocardial infarction, renal impairment and acute renal failure, without the concomitant liability of adverse effects associated with the racemic mixture of amlodipine.

Methods For The Selective Treatment Of Tumors By Calcium-Mediated Induction Of Apoptosis

Available evidence indicates that tumor cells exhibit consistent abnormalities in Calcium influx and intracellular storage of sequestered Calcium when compared to normal cells. The present invention provides clinical methods by which such differences are exploited to induce Apoptosis selectively in tumor cells while sparing normal cells. These methods are based upon employing drugs that, acting alone or in synergistic combinations, produce an increase in intracellular Calcium loading such that either or both of two major Apoptotic pathways are triggered to produce selective killing of malignant cells. Since the invention is based upon fundamental cell cycle requirements, to the extent that Calcium handling abnormalities are a general characteristic of the malignant state, the methods presented here are widely applicable regardless of tissue of origin and degree of cellular de-differentiation.
