The inhalation drugs and their function to treat PAH.

Inhalation drugs	Function
Prostacyclin analogues	Stabilize role in maintaining the system of the intravascular environment
Nitric oxide	Inhibit platelet aggregation, smooth muscle cell proliferation
Soluble guanylate cyclase (sGC) agonist	Catalyze the formation of cGMP
PDE inhibitors	Regulate their hydrolysis in the cell
Rho kinase inhibitors	Mediate a series of phosphorylation reactions of their downstream effectors
Vasoactive intestinal peptide	Diastole smooth muscle cells and antiproliferative effects
Adrenomedullin	Inhibit smooth muscle proliferation and migration
