Proteins and Peptide Drugs: Different Routes of Administration for Their Delivery

摘要

Proteins and peptides have the wide range of therapeutic agents emerged within and the administration is through needle and syringe i.e., parenteral delivery is the choice of route of administration, but it has drawn some drawback related to patient incompliance such as causing pain during administration, sterility and cost of the product though the bioavailability is 100%. The route of administration plays an important role as it have an impact on the therapeutic outcome of the drug, with the advancement in the branch of pharmaceutical biotechnology. Based on the biophysical and biochemical properties a delivery system was designed for protein and peptide based therapeutic and clinical application have come into existence through non-invasive delivery and in addition, this dosage form can be significantly self-administered by patients, manufacturing cost would be less compared to the injections. The main aim is to focus in this review article is the recent advances in the delivery of therapeutic proteins and peptides via different non-invasive routes and the barriers affecting the drug transportation, approaches, advantages, challenges.
