Concurrent use of antidepressants and propranolol: case report and theoretical considerations.
The therapeutic indications for propranolol have been steadily increasing in recent years. Propranolol and other beta-adrenergic blocking agents are now generally acknowledged to be helpful in the management of hypertension, certain cardiac arrhythmias, migraine, essential tremor, angina pectoris, and most recently, immediately after myocardial infarction (Frishman, 1981; Norwegian Multicenter Study Group, 1982). Because of the myriad clinical settings in which propranolol has been found to be of benefit, the interactions of these drugs with other commonly utilized pharmacological agents is of great pragmatic interest. In this report we describe the successful concomitant clinical use of propranolol and an antidepressant drug. This finding is also of interest because of recent theories concerning the mechanism of action of antidepressant drugs. Because propranolol readily penetrates into the CNS, it blocks beta-adrenergic receptors in both the periphery and the CNS (Weiner, 1980). Much attention has been focused recently on the effects of long-term antidepressant therapy on central beta-adrenergic receptors in the brain as a possible mechanism of action of these drugs. The concurrent use of propranolol and an antidepressant drug in the patient described in this report did not attenuate the therapeutic effects of the antidepressant.
