Beta-blocker overdose is rare but serious. This review details toxicity, clinical presentation, and treatment for beta-adrenergic receptor antagonist overdoses.
Area of Science:
- Pharmacology
- Toxicology
- Cardiology
Background:
- Beta-adrenergic receptor blockers are widely used for various cardiovascular and non-cardiovascular conditions.
- These drugs act as competitive antagonists at beta(1) and/or beta(2) adrenergic receptors.
- Overdoses, though uncommon, pose significant risks of morbidity and mortality.
Purpose of the Study:
- To review the properties of beta-adrenergic receptor blockers.
- To outline toxic and referral doses for beta-blocker overdoses.
- To analyze the clinical presentation, diagnosis, and management of beta-blocker overdose.
Main Methods:
- Literature review of beta-adrenergic receptor blocker properties and overdose management.
- Analysis of clinical manifestations, diagnostic approaches, and treatment strategies.
- Evaluation of clinical course and prognosis in beta-blocker overdose cases.
Main Results:
- Beta-blocker overdoses present with cardiovascular, neurologic, and pulmonary complications.
- Treatment strategies include gastrointestinal decontamination, pharmacologic interventions (atropine, glucagon, insulin), and supportive care.
- Extracorporeal procedures and cardiac pacing may be indicated in severe cases.
Conclusions:
- Understanding beta-blocker properties is crucial for managing overdose.
- Prompt diagnosis and appropriate treatment are essential for improving outcomes.
- This review provides guidance on toxic doses, clinical presentation, and management of beta-blocker overdose.

Adrenergic Antagonists: Pharmacological Actions of ɑ-Receptor Blockers
α1-blockers: These drugs inhibit α1-adrenoceptors on smooth muscle cells, resulting in vasodilation. This vasodilation lowers blood pressure, making α1-blockers valuable in treating hypertension. Additionally, α1-blockers effectively address urinary obstruction...

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
