Trends in prescription of anti-seizure medicines for Japanese pediatric outpatients during 2013–2019

Temporal trends in prescriptions of anti-seizure medicines (ASMs) for children, including newer ASMs, are unclear. We investigated ASM prescription trends for pediatric outpatients in Japan. The MDV analyzer® was used to analyze the MDV database containing de-identified hospital administrative data. Administrative data as of June 2021 including pediatric outpatients (0–17 years) with epilepsy, visiting 123 acute diagnostic procedure combination hospitals during 2013–2019, were used. Annual ASMs prescription trends were calculated, based on proportions. The Cochran–Armitage trend test evaluated the proportion of prescriptions for each ASM. ASMs most often prescribed were valproic acid, carbamazepine, and levetiracetam, regardless of sex. In girls, the proportion of valproic acid and carbamazepine prescriptions decreased from 37.93% to 26.84%, and from 24.80% to 15.78%, respectively (p < 0.0001). Conversely, the proportion of levetiracetam prescriptions increased from 6.40% to 28.18% (p < 0.0001). In boys, the proportion of valproic acid and carbamazepine prescriptions decreased, from 36.58% to 32.20% and from 26.42% to 16.85%, respectively (p < 0.0001). The proportion of levetiracetam prescriptions increased from 5.64% to 23.02% (p < 0.0001). Overall, the proportion of valproic acid and carbamazepine prescriptions declined, whereas levetiracetam prescriptions increased. Trends in ASM prescriptions among pediatric outpatients with epilepsy in Japan have shifted towards more recently available ASMs.
