Cocaine intoxication

Overview


Plain-Language Overview

Cocaine intoxication occurs when a person uses too much cocaine, a powerful stimulant drug that affects the brain and body. It primarily impacts the nervous system and the cardiovascular system, causing symptoms like a fast heartbeat, high blood pressure, and intense feelings of excitement or anxiety. The drug increases levels of certain chemicals in the brain, leading to increased energy, restlessness, and sometimes dangerous behaviors. It can also cause serious problems such as chest pain, seizures, or difficulty breathing. The effects can be sudden and severe, making it a medical emergency in many cases.

Clinical Definition

Cocaine intoxication is a clinical syndrome resulting from acute exposure to cocaine, a potent sympathomimetic agent that blocks the reuptake of norepinephrine, dopamine, and serotonin in the central nervous system. This leads to excessive stimulation of the sympathetic nervous system, causing tachycardia, hypertension, mydriasis, and hyperthermia. The condition is characterized by a combination of neurologic, cardiovascular, and psychiatric manifestations, including agitation, paranoia, chest pain, and seizures. Cocaine intoxication can precipitate life-threatening complications such as myocardial infarction, stroke, and arrhythmias. Diagnosis is critical due to the potential for rapid deterioration and requires recognition of the characteristic clinical features and history of cocaine use.
