GH1 and cystic fibrosis: Similarly, human growth hormone (hGH), which is stabilized using polymeric carriers to prevent degradation before reaching systemic circulation, demonstrates effective absorption through the lungs’ large surface area, and rhDNase, used for cystic fibrosis treatment, is often formulated in aerosolized solutions with stabilizing excipients to maintain bioactivity during inhalation and deposition in the lung, aiding in breaking down mucus in the lungs, thus improving respiratory function [61].
