Protein drug delivery Proteins and peptides represent a rapidly expanding frontier in therapeutic development. Their inherent specificity, high efficacy, and generally lower toxicity compared to traditional small-molecule drugs position them as potent agents for treating a wide array of diseases. However, realizing the full therapeutic promise of these complex biomolecules hinges critically on effective drug delivery. This article delves into the multifaceted challenges and cutting-edge solutions in protein and peptide drug delivery, exploring different pharmaceutical approaches and recent advances adopted for protein and peptide drug delivery.

Proteins, defined as large biomolecules composed of amino acid chains, and peptides, which are shorter chains of amino acids, offer unparalleled precision in targeting biological pathways. As noted in the available research, Protein and peptide-based drugs have great potential applications as therapeutic agents. Their intricate three-dimensional structures allow for highly specific interactions with cellular targets, leading to more precise and potent therapeutic effects作者：M Nicze·2024·被引用次数：64—Scientists have been strenuously searching for noveldeliverymethods enablingpeptideandproteindrugs (PPDs) to be administered enterally.. This specificity, however, also contributes to their inherent instability and susceptibility to degradation within the body, posing significant hurdles for conventional administration routes.

Historically, pharmaceutical proteins and peptides have predominantly been administered via parenteral routes, such as intramuscular (IM), intravenous (IV), and subcutaneous injections. While these methods ensure direct access to the bloodstream, bypassing the digestive system's harsh environment, they are associated with patient discomfort, the risk of infection, and the inconvenience of needle-and-syringe administration. The aspiration for less invasive methods, particularly oral and transdermal peptide drug delivery, has driven extensive research. Scientists have been strenuously searching for novel delivery methods enabling peptide and protein drugs (PPDs) to be administered enterally.Therapeutic Protein And Peptide Formulation And Delivery ...

The peroral route presents a particular challenge for PP drug delivery. The gastrointestinal (GI) tract is a hostile environment characterized by low pH, enzymatic degradation, and an intestinal barrier that restricts the absorption of large molecules. Overcoming these physiological barriers is paramount for improving oral bioavailability. Consequently, different pharmaceutical approaches have been developed to enhance the stability and permeability of these biologics. These include formulating the drugs with protective excipients, developing self-emulsifying drug delivery systems, and employing mucoadhesive strategies to prolong residence time in the GI tract. Improving the oral bioavailability of these fragile molecules is a primary focus.

Beyond oral delivery, transdermal and other non-invasive routes are also gaining traction.作者：J Shaji·2008·被引用次数：393—This review summarizesdifferent pharmaceutical approacheswhich overcome various physiological barriers that help to improve oral bioavailability. Transdermal peptide drug delivery offers the advantage of continuous drug absorption and avoidance of first-pass metabolism. However, the stratum corneum, the outermost layer of the skin, acts as a formidable barrier to the passage of peptides and proteins.Review Article - Protein and peptide drug delivery system Strategies to overcome this include utilizing penetration enhancers, microneedle arrays, and iontophoresis. Furthermore, alternative convenient delivery methods, such as eye drops, are being explored where systemic absorption can be extremely rapid, avoiding first-pass metabolism.Protein and Peptide in Drug Targeting and its Therapeutic ... This demonstrates that in specific contexts, the mode of delivery is convenientProtein and Peptide in Drug Targeting and its Therapeutic ....

The complexity of producing protein or peptide therapeutics is highly complex, often involving numerous sophisticated manufacturing steps. Therefore, efficient and reliable drug delivery systems are not merely an adjunct but an integral part of the therapeutic development process.This reference/text coversfundamentals of peptide and protein drug delivery, including such considerations as synthesis, physical chemistry and biochemistry, ... The field is witnessing the emergence of various novel protein and peptide delivery systems, including nanoparticle-based carriers, liposomes, hydrogels, and conjugates with polymers like polyethylene glycol (PEG). Conjugates of polymers with proteins have also shown strong potency in the field of drug delivery, with PEGylation being a particularly successful strategy to improve solubility, stability, and prolong the circulation half-life of protein drugs.

Moreover, a growing area of interest is intracellular delivery of peptides and proteins. For many therapeutic applications, the drug needs to reach specific cellular compartments to exert its effect. This requires sophisticated delivery systems capable of bypassing cell membranes and releasing their cargo in the cytoplasm or nucleus. Research into peptide-based carriers for delivery of various toxic drugs, as well as for therapeutic proteins and peptides themselves, highlights the versatility of these approaches.

Understanding the fundamentals of peptide and protein drug delivery is crucial for advancing this field. This encapsulates not only the pharmacokinetic and pharmacodynamic properties of the drugs but also the engineering of sophisticated delivery systems.Peptide and Protein Drug Delivery | Vincent Lee The development of innovative platforms for formulation and evaluation of delivery systems for proteins and macromolecules is essential for translating promising peptide and protein candidates into viable clinical treatments. While protein and peptide based therapeutics are typically administered by injection due to historical challenges, the future holds great promise for alternative, patient-centric delivery methods. The ongoing exploration of oral protein and peptide drug delivery and other non-invasive routes underscores a commitment to enhancing patient compliance and expanding the therapeutic reach of these powerful biomoleculesThe Current and Promising Oral Delivery Methods for Protein.
