Pharma, Pharmaceutics and Biotechnology Conference

Therapeutic agents that represent significant prospects in the pharmaceuticals industry are peptides and proteins, which possess great specificity and efficacy but hold lower toxicity compared to traditional small-molecule drugs. A new generation of therapeutics based on peptides and proteins has been developed to combat diseases like cancer, diabetes, and autoimmune diseases due to improvement over the years in biotechnological methods. However, successful delivery of these biologics has its uniqueness and demands special attention to maximize the therapeutic potential.

There is a greatly influencing effect on the bioavailability in the case of peptides and proteins due to their large size of molecules and susceptibility to enzymatic degradation, particularly when these are delivered through conventional routes such as oral or subcutaneous routes. For instance, orally administered peptide drugs are generally ineffective since they undergo destruction in the gastrointestinal tract and poor absorption onto the intestinal lining. Therefore, new delivery methods have been considered as it tries to improve stability and effectiveness for these therapeutics. Probably, the greatest innovation of peptide and protein drug delivery is the development of new delivery systems. Encapsulation of peptides and proteins within nanoparticle-based carriers may protect them from degradation and enhance their transport across biological barriers.

They improve stability and bioavailability, but they also release therapeutic agents in controlled and sustained ways, enhancing patient compliance and treatment outcomes. Transdermal delivery and inhalation delivery are also under investigation as non-invasive routes for the delivery of peptide and protein therapeutics. For instance, peptide therapeutics can be delivered transdermal with the help of a micro needle patch, thereby facilitating direct injections to enter systemic circulation.

Inhaled delivery can also offer rapid absorption of proteins into the respiratory system, thus becoming a possible route for delivering therapeutics to patients with respiratory diseases. Despite such developments, important challenges still persist for the drug delivery of peptides and proteins. These include formulation stability, potential for inducing immunogenic reactions, and dosing requirements, among others. Additionally, the regulatory environment paints a daunting picture of testing and validation for peptide and protein-based therapeutics for the purpose of safety and efficacy.

This discussion on the latest development trends in drug delivery systems of peptides and proteins as well as new formulation strategies, emerging technologies, and challenges related to development and commercialization of these biologics promises to get participants informed on how really to tap into the deep therapeutic potential of peptides and proteins for modern medicine by way of real-life case studies and innovations in drug delivery.
