Hepatotoxicity associated with cocaine abuse
1Department of Surgery, University of Pittsburgh School of Medicine, Pennsylvania 15213.
Summary
Cocaine use can harm the liver through mechanisms involving the P-450 enzyme system and free radicals. This review covers animal studies and clinical cases of cocaine-induced liver injury.
Area of Science:
- Hepatology
- Toxicology
- Pharmacology
Background:
- Cocaine is a potent stimulant with known systemic toxicities.
- Hepatotoxicity is a recognized, though less common, adverse effect of cocaine use.
Purpose of the Study:
- To review the animal models and mechanisms of cocaine-induced liver injury.
- To discuss the role of the cytochrome P-450 enzyme system and free radicals in cocaine hepatotoxicity.
- To summarize the existing clinical literature on cocaine hepatotoxicity.
Main Methods:
- Review of animal studies investigating cocaine's effects on the liver.
- Discussion of biochemical pathways implicated in cocaine toxicity.
- Synthesis of published clinical case reports of cocaine-associated liver damage.
Main Results:
- Animal studies implicate the P-450 enzyme system in cocaine metabolism and subsequent liver injury.
- Evidence suggests that reactive oxygen species (free radicals) play a critical role in the pathogenesis of cocaine hepatotoxicity.
- Clinical literature demonstrates a spectrum of liver injury patterns associated with cocaine use.
Conclusions:
- The P-450 system and free radical generation are key mechanisms underlying cocaine hepatotoxicity in animal models.
- Clinical manifestations of cocaine-induced liver injury are increasingly documented, highlighting the need for awareness among healthcare providers.
