The Inherent Challenges in Protein and Peptide Delivery

Despite their therapeutic prowess, proteins and peptides face substantial challenges when it comes to effective drug delivery. Their large molecular size, complex three-dimensional structures, and susceptibility to enzymatic degradation, particularly in the gastrointestinal tract, significantly limit their oral bioavailability.

The common routes of administration for pharmaceutical proteins and peptides often involve parenteral methods such as intramuscular (IM), intravenous (IV), and subcutaneous injections. While effective, these methods are invasive and can lead to patient discomfort, poor compliance, and variable absorption rates. The desire for non-invasive and more convenient administration methods, such as the oral and transdermal peptide drug delivery, remains a strong driving force in the field.

The search for a method to find an optimal way to deliver drugs with these characteristics has led to the exploration of various sophisticated protein and peptide drug delivery systems. These systems are designed to protect the therapeutic molecule from degradation, facilitate its absorption across biological barriers, and ensure its targeted release to the desired site of action within the body.
