Acute and chronic intoxication with carbromal preparations

Area of Science:

• Toxicology
• Pharmacology
• Clinical Chemistry

Background:

• Carbromal preparations are currently available without prescription.
• Abuse of these drugs leads to acute intoxications and chronic bromide accumulation.
• Bromism is a significant clinical concern associated with carbromal use.

Purpose of the Study:

• To present the clinical features and treatment of carbromal overdoses and bromism.
• To describe laboratory findings in carbromal intoxication and bromism.
• To emphasize the need for prescription control of carbromal preparations.

Main Methods:

• Case study of three suicidal carbromal overdoses and two bromism patients.
• Qualitative Thin-Layer Chromatography (TLC) for drug detection.
• Quantitative High-Performance Liquid Chromatography (HPLC) for drug assays in body fluids.
• Determination of plasma chloride and bromide ion concentrations.

Main Results:

• Clinical manifestations of acute carbromal overdose and chronic bromism were observed.
• Laboratory assays confirmed the presence of carbromal and elevated bromide levels.
• Plasma bromide levels correlated with clinical presentation and recovery.

Conclusions:

• Carbromal abuse poses a significant risk for acute and chronic intoxication.
• Laboratory monitoring is crucial for diagnosing and managing carbromal-induced toxicity.
• Making carbromal preparations prescription-only is recommended to mitigate public health risks.
