How to deal with the coke

Acute cocaine toxicity can manifest with several cardiovascular issues such as tachycardia, dysrhythmia, hypertension, and coronary vasospasm. This systematic review collated all of the available evidence for potential treatment options.

Here is what the review found (there is also an 'other agents' section for medications with less published reports):

  • Benzodiazepines and other GABA-active agents: Benzodiazepines may not always effectively mitigate tachycardia, hypertension, and vasospasm from cocaine toxicity.
  • Calcium channel blockers: Calcium channel blockers may decrease hypertension and coronary vasospasm, but not necessarily tachycardia.
  • Nitric oxide-mediated vasodilators: Nitroglycerin may lead to severe hypotension and reflex tachycardia.
  • Alpha-adrenoceptor blocking drugs: Alpha-1 blockers may improve hypertension and vasospasm, but not tachycardia, although evidence is limited.
  • Alpha-2-adrenoceptor agonists: There were two high-quality studies and one case report detailing the successful use of dexmedetomidine.
  • Beta-blockers and β/α-blockers: No adverse events were reported for use of combined β/α-blockers such as labetalol and carvedilol, which were effective in attenuating both hypertension and tachycardia.
  • Antipsychotics: Antipsychotics may improve agitation and psychosis, but with inconsistent reduction in tachycardia and hypertension and risk of extrapyramidal adverse effects.
  • Sodium bicarbonate: Twelve case reports documented treatment of dysrhythmia with IV sodium bicarbonate, with seven reporting successful termination.
