Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists

150
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

Summary

Treprostinil shows therapeutic benefits for neonatal pulmonary hypertension, particularly in infants with congenital diaphragmatic hernias. While hypotension is a noted side effect, management strategies exist, suggesting potential for reducing neonatal morbidity and mortality.

Area of Science:

  • Neonatal Medicine
  • Pharmacology
  • Pediatric Cardiology

Background:

  • Treprostinil, a prostacyclin analogue, is widely used for pulmonary hypertension in pediatric and adult populations.
  • Its use in neonatal intensive care units (NICUs) for treating neonatal pulmonary hypertension is less common.

Purpose of the Study:

  • To evaluate the efficacy of treprostinil for treating pulmonary hypertension in neonates.
  • To assess the potential benefits and risks of treprostinil in the NICU population.

Main Methods:

  • A literature review was conducted using PubMed, CINAHL, and Embase databases.
  • Twelve articles published between 2014 and 2024, focusing on treprostinil use in patients under one year of age, were included.
  • Studies were selected based on relevance to treprostinil use in the NICU, excluding those on genetics and congenital heart disease.

Main Results:

  • Treprostinil demonstrated therapeutic benefits in neonates, particularly those with congenital diaphragmatic hernias and potentially premature infants.
  • Hypotension was identified as an adverse effect, but effective management strategies are available.
  • The findings suggest treprostinil can be a valuable treatment option for neonatal pulmonary hypertension.

Conclusions:

  • Initiating treprostinil in the NICU may reduce the severity of persistent pulmonary hypertension of the newborn (PPHN), thereby decreasing neonatal morbidity and mortality.
  • Further research is required to establish optimal treprostinil initiation timing, treatment duration, and its efficacy in other PPHN-causing conditions.
  • Investigating potential effects in preterm infants and other neonatal populations is also recommended.
