Cm. Stork et R. Cantor, PEMOLINE INDUCED ACUTE CHOREOATHETOSIS - CASE-REPORT AND REVIEW OF THE LITERATURE, Journal of toxicology. Clinical toxicology, 35(1), 1997, pp. 105-108
Background: Pemoline is an oxazolidine derivative that is structurally
different from amphetamines and used in the treatment of attention de
ficit disorder. Pemoline has not been commonly associated in the liter
ature as a cause of acute movement disorders. The following case descr
ibes two children acutely poisoned with pemoline who experienced profo
und choreoathetosis. Case Report: Two, 3-year-old male, identical twin
siblings presented to the emergency department after found playing wi
th a an empty bottle of pemoline originally containing 59 tablets. The
children had a medical history significant for attention deficit diso
rder previously treated with methylphenidate without success. This was
their first day of pemoline therapy. The choreoathetoid movements beg
an 45 min to 1 h after ingestion. The children gave no history of prio
r movement disorders and there was no family history of movement disor
ders. The children received gastrointestinal decontamination and high
doses of intravenous benzodiazepines in an attempt to control the chor
eoathetoid movements. Despite treatment, the children continued to hav
e choreoathetosis for approximately 24 hours. Forty-eight hours after
admission, the children appeared to be at their baseline and were disc
harged home. Conclusion: Pemoline associated movement disorder has bee
n rarely reported in the acute toxicology literature, The possibility
of choreoathetoid movements should be considered in patients presentin
g after pemoline overdose.
