Sustained-release verapamil overdose can occur, even in suicide attempts. This case highlights crucial treatment strategies for verapamil toxicity, emphasizing prompt medical intervention for calcium-channel blocker overdose.

Area of Science:

Pharmacology
Cardiology
Toxicology

Background:

Calcium-channel modulators, including verapamil, are essential vasodilators for treating hypertension.
Immediate-release verapamil has documented toxicity reports in medical literature.
Essential hypertension management often involves calcium-channel blockers.

Observation:

A case of intentional sustained-release verapamil overdose is presented.
The overdose was a consequence of a suicide attempt.
This highlights a critical scenario of significant verapamil ingestion.

Findings:

Sustained-release verapamil overdose presents unique pharmacokinetic challenges.
Effective treatment involves supportive care and specific interventions for calcium-channel blocker toxicity.

The case details the management approach and patient outcomes.

Implications:

Understanding verapamil overdose management is crucial for emergency medicine and toxicology.
This case underscores the importance of considering formulation (immediate vs. sustained-release) in overdose scenarios.
It contributes to the literature on managing severe calcium-channel blocker toxicity.
