Propranolol in Cocaine Use Disorder: Treatment Considerations
Critical Distinction: Acute Intoxication vs. Chronic Treatment
- The American Heart Association explicitly recommends against beta-blockers, including propranolol, in patients showing signs of acute intoxication, such as euphoria, tachycardia, and hypertension, due to the risk of unopposed alpha-stimulation causing paradoxical hypertension and worsened coronary vasospasm 2
- First-line treatment for acute cocaine-related cardiovascular complications should be benzodiazepines, nitroglycerin, and calcium channel blockers, such as verapamil or diltiazem, as recommended by the American College of Cardiology 1, 3, 4
Clinical Algorithm for Propranolol Use
- Do NOT use propranolol if a patient shows signs of acute intoxication, including euphoria, acute tachycardia, hypertension, or recent cocaine use within 4-6 hours, as advised by the American Heart Association 2, 5
- Patients with active substance use disorders often have poor medication compliance, which can impact propranolol efficacy, according to the American College of Cardiology 7, 3
Preferred Alternatives for Cocaine Use Disorder
- Behavioral interventions, such as contingency management combined with community reinforcement approach, remain the primary evidence-based treatment for cocaine use disorder, as recommended by the American Psychiatric Association 6
- No pharmacological agent has strong evidence for treating cocaine use disorder in general populations, highlighting the need for alternative approaches, such as transcranial magnetic stimulation, which is under investigation for reducing cocaine craving, as noted by the National Institute on Drug Abuse 6
