Advances in Peptide Delivery Systems
A major challenge in peptide therapeutics is ensuring stability, bioavailability, and targeted delivery. Peptides are prone to enzymatic degradation and rapid clearance. Advances in delivery systems have addressed these limitations through chemical modifications and innovative formulations.
Cyclization and stapling of peptides increase stability and receptor affinity. Lipidation or PEGylation extends circulation half-life, while nanoparticle carriers enable tissue-specific targeting. Oral, transdermal, and inhalable peptide formulations are being developed to improve patient compliance and expand therapeutic options.
These advances make peptide therapeutics more practical for chronic diseases, enhancing efficacy and safety while reducing dosing frequency.
