Methods and compositions 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. |
