Abstract

After decades without approved pharmacotherapies, mitochondrial disease care is shifting. Two FDA approvals emerged in 1 year, elamipretide (Forzinity) for Barth syndrome and deoxynucleoside therapy (Kygevvi) for TK2 deficiency, with another under review. Zink et al.1 suggest sildenafil (Viagra) could treat Leigh syndrome, highlighting drug repurposing for severe pediatric mitochondrial disease.
