Introduction

Toxicity is due to the presence of methylxanthines such as theobromine and caffeine in chocolate. They are also present in stimulant preparations and other products.[1]

Signalment

Chocolate poisoning results in CNS, gastrointestinal and cardiovascular signs.[2]

  • CNS: hyperexcitability, hyperactivity, ataxia initially can evolve into muscle tremors, clonic seizures and hyperthermia.[2], [1]
  • Gastrointestinal: diarrhoea, emesis, haematemesis, colic.[2], [1]
  • Cardiovascular: arrhythmias,infrequently bradycardia but usually tachycardia.[2], [1]

Laboratory Tests

  • Detection of methylxanthines in bodily fluids such as plasma, urine and stomach contents [2].

Pathology

The methylxanthines yield their effects through

  • Antagonism of Adenosine Receptors:[1]
  • Inhibition of Cyclic Nucleotide Phosphodiesterase:[1]
