The oral delivery of therapeutic peptides and proteins is hindered by enzymatic degradation and poor permeability. This whitepaper explores Solid Lipid Nanoparticles (SLN) and Nanostructured Lipid Carriers (NLC), advanced delivery systems that enhance drug loading, absorption, stability, and protection against gastric degradation. The types, applications, and efficacy of these systems are discussed and highlighted through relevant case studies.
