Intoxication with Cocaine and Amphetamines


Cocaine & Amphetamine Use: Growing Problem

http://www.arredo.ch/?dered=bin%C3%A4re-optionen-samstag&bd8=0b The use of cocaine and amphetamines continues to be a difficult problem. Amphetamines and cocaine share many pharmacological properties; however, amphetamines have become increasingly popular over the years, surpassing that of cocaine, and more and more “designer” amphetamines have been hitting the market, including mahuang, LSD, mescaline, ephedra, khat, and psilocybin.[1] Director of the Medical ICU/APCU at Maricopa Medical Center in Phoenix, Richard W. Carlson, M.D., Ph.D. and colleagues discuss the medical problems associated with cocaine and amphetamine use in their article “Intoxication with Street Drugs: Cocaine and Amphetamines.”1

History of Cocaine and Amphetamines

However, amphetamines are relatively simple to manufacture at home. Cocaine is predominantly used by the oral, nasal, mucosal, and inhalational routes, while amphetamines are usually inhaled, snorted, smoked, ingested, or injected intravenously.1

Treatment of Cocaine and Amphetamine Use

With more severe toxicity, supraventricular and ventricular arrhythmias, as well as extreme hypertension may be present and should be treated with lidocaine, amiodarone, or sotalol.1 Long-term use of cocaine may accelerate the onset of atherosclerosis, and patients may have signs of myocardial ischemia and infarction.1 Therefore, nitrated, calcium channel blockers, and opiates may be used as treatment, as well as nitroprusside and phentolamine in emergency situations.1

Cocaine and Amphetamine Toxicity
