Overview of Antihypertensive Drug Poisoning

Antihypertensive drugs are commonly prescribed to manage high blood pressure and may include various classes such as diuretics, beta-blockers, ACE inhibitors, and calcium channel blockers. Accidental poisoning can occur due to factors such as medication errors, improper storage, or confusion with other medications. Symptoms of poisoning can vary widely depending on the specific drug involved but may include hypotension, bradycardia, dizziness, and in severe cases, shock or respiratory distress[1].

Initial Assessment and Stabilization

1. Immediate Evaluation

Upon presentation, the first step is to assess the patient's vital signs and level of consciousness. This includes checking blood pressure, heart rate, respiratory rate, and oxygen saturation. A thorough history should be obtained, including the type and amount of antihypertensive drug ingested, the time of ingestion, and any co-ingestants[2].

2. Stabilization

If the patient exhibits severe symptoms such as hypotension or bradycardia, immediate stabilization is critical. This may involve:
- Intravenous fluids: To manage hypotension and maintain blood volume.
- Vasopressors: In cases of severe hypotension that does not respond to fluid resuscitation, medications such as norepinephrine may be administered to support blood pressure[3].

Decontamination

1. Activated Charcoal

If the patient presents within one hour of ingestion and is alert, activated charcoal may be administered to reduce absorption of the drug. The use of activated charcoal is contraindicated in patients with altered mental status or those who are unable to protect their airway[4].

2. Gastric Lavage

In certain cases, especially with life-threatening ingestions, gastric lavage may be considered. However, this is less commonly used due to the risk of complications and is generally reserved for specific situations[5].

Symptomatic Treatment

1. Management of Specific Symptoms

• Bradycardia: Atropine may be used to increase heart rate if bradycardia is significant.
• Hypotension: As mentioned, intravenous fluids and vasopressors are key interventions.
• Respiratory distress: Supplemental oxygen or mechanical ventilation may be necessary if the patient is unable to maintain adequate oxygenation[6].

2. Monitoring

Continuous monitoring of vital signs and cardiac rhythm is essential, as patients may develop complications that require prompt intervention. Electrocardiogram (ECG) monitoring can help detect arrhythmias associated with certain antihypertensive overdoses[7].

Consultation and Further Management

In cases of severe poisoning or when the specific antihypertensive drug involved is known to have specific antidotes or treatment protocols, consultation with a poison control center or a medical toxicologist is recommended. They can provide guidance on advanced treatment options and monitoring protocols tailored to the specific drug involved[8].

Conclusion

The management of accidental poisoning by antihypertensive drugs requires a systematic approach that includes initial assessment, stabilization, decontamination, and symptomatic treatment. Prompt recognition and intervention are crucial to prevent serious complications and ensure patient safety.
