Delivery Routes: Navigating the Landscape

The route of administration significantly impacts the efficacy and patient experience. While parenteral delivery in liquid form remains the most common method for protein delivery, offering direct access to the systemic circulation, it often involves injections. The focus is increasingly shifting towards novel non-injectable formulation approaches of peptides and proteins to enhance patient acceptance and compliance.

Non-invasive delivery of peptide and protein drugs is a key area of research. This includes exploring oral, pulmonary, transdermal, and nasal routes. However, developing effective oral delivery of protein and peptide drugs presents substantial challenges due to the harsh gastrointestinal environment, including enzymatic degradation and low pH.

Understanding Protein Degradation and Stability

A thorough understanding of protein and peptide formulation necessitates an in-depth knowledge of degradation pathways. The formulation and evaluation of delivery systems for proteins must account for potential degradation mechanisms, including hydrolysis, oxidation, deamidation, and aggregation. Identifying these pathways is crucial for designing stable formulations. For instance, the experience of developing a number of protein and peptide formulations has taught researchers to look for three principal degradation pathways. Factors such as pH, temperature, shear stress, and the presence of specific excipients can all influence the stability of proteins and peptides.

The Role of Recombinant DNA Technology

The advent of recombinant DNA techniques now allow us to produce therapeutic proteins in a commercially viable form. This technological breakthrough has been instrumental in making a wide array of proteins and peptides available for therapeutic use. However, the production process itself can introduce challenges related to purity and post-translational modifications, which must be carefully managed during formulation.
