Clinical Description

Definition

The code T46.6X1 is used to document instances where a patient has been unintentionally poisoned by medications designed to lower lipid levels in the blood (antihyperlipidemic drugs) or to prevent the hardening of arteries (antiarteriosclerotic drugs). These medications are commonly prescribed to manage conditions such as hyperlipidemia and cardiovascular diseases.

Common Antihyperlipidemic and Antiarteriosclerotic Drugs

• Statins: Such as atorvastatin, simvastatin, and rosuvastatin, which are used to lower cholesterol levels.
• Fibrates: Like fenofibrate and gemfibrozil, which help reduce triglyceride levels.
• Bile Acid Sequestrants: Such as cholestyramine, which bind bile acids to lower cholesterol.
• Niacin: A vitamin that can help improve cholesterol levels.
• PCSK9 Inhibitors: Such as alirocumab and evolocumab, which are newer agents that significantly lower LDL cholesterol.

Mechanism of Poisoning

Accidental poisoning can occur due to various reasons, including:
- Overdosage: Patients may inadvertently take more than the prescribed dose.
- Drug Interactions: Concurrent use of other medications may enhance the effects of antihyperlipidemic drugs, leading to toxicity.
- Misunderstanding Dosage Instructions: Patients may misinterpret instructions, leading to unintentional overdose.

Symptoms of Poisoning

Symptoms of poisoning by these drugs can vary based on the specific medication involved but may include:
- Muscle pain or weakness (myopathy)
- Liver dysfunction (elevated liver enzymes)
- Gastrointestinal disturbances (nausea, vomiting, diarrhea)
- Hypotension (low blood pressure)
- Confusion or altered mental status in severe cases

Diagnosis and Management

Diagnosis

The diagnosis of accidental poisoning by antihyperlipidemic and antiarteriosclerotic drugs typically involves:
- Clinical History: Gathering information about the patient's medication use and any potential accidental ingestion.
