Optically pure (S) metoprolol, which is substantially free of the (R) enantiomer, is a potent beta-blocker for treating myocardial infarction and for relieving the symptoms of angina pectoris, cardiac arrhythmia and hypertension in individuals. A method is disclosed utilizing the optically pure (S) configurational enantiomer of metoprolol for treating cardiovascular disorders while reducing undesirable side effects associated with the administration of beta-blockers. |
