Metoprolol for intermittent explosive disorder.

The American Journal of Psychiatry

|September 1, 1985

Summary

This summary is machine-generated.

Metoprolol, a selective beta 1-adrenoreceptor blocker, effectively treated two patients with intermittent explosive disorder when other medications failed. This suggests metoprolol may be a valuable therapeutic option for managing explosive outbursts.

Background:

Intermittent explosive disorder (IED) is characterized by recurrent, impulsive, aggressive outbursts.
Current pharmacological treatments for IED have limited efficacy and significant side effects.
Previous treatments with propranolol and carbamazepine were unsuccessful in the presented cases.

Observation:

Two patients diagnosed with intermittent explosive disorder were treated with metoprolol.
Metoprolol is a selective beta 1-adrenoreceptor blocker.
Both patients had a history of treatment resistance to other medications.

Findings:

Both patients exhibited dramatic clinical improvement following metoprolol administration.
The selective beta 1-adrenoreceptor blockade by metoprolol appeared to mitigate aggressive episodes.

Symptom reduction was observed in both individuals under metoprolol treatment.

Implications:

Metoprolol demonstrates potential as a novel therapeutic agent for intermittent explosive disorder.
These findings suggest a possible role for beta-adrenergic modulation in managing impulsive aggression.
Further research is warranted to explore the efficacy and safety of metoprolol in larger IED populations.
