Conclusion
Ondansetron, an anti-emetic with a relatively high safety profile, is
prescribed globally for the symptom of vomiting. This was one of the
first cases of KS characterized by non-ischaemic myocardial injury and
elevated troponin due to an anaphylactoid reaction to ondansetron. KS
have potential effects on biochemical parameters such as cardiac
troponin along with an anaphylactoid phenomenon after an intravenous
administration of the recommended dose. Thus, this case warrants more
research for establishing the pathophysiology of KS, the association of
cardiac troponin with anaphylactoid reactions, and ensure the judicial
use of ondansetron.
