Authors have submitted a letter to the editor regarding Li L, Zhu X, Chen X, Gao J, Ding C, et al. Advances in targeted therapy for pulmonary arterial hypertension in children. Eur J Pediatr. 2022 Dec 17 [1].

It is a well-written letter and deserves dissemination. We accept the authors’ recommendations on the ambrisentan dosage for treating pulmonary hypertension in children. We hope the letter will be published to provide clinicians with a standardized reference method for using ambrisentan in children with pulmonary hypertension.
