Market Overview
The global oral proteins and peptides market is undergoing a transformative growth phase as the demand for advanced drug delivery systems continues to accelerate. Valued at USD 6,350.0 million in 2023, the market is projected to reach USD 7,462.0 million in 2024 and further expand to USD 26,936.2 million by 2031, growing at an impressive compound annual growth rate (CAGR) of 20.13% during the forecast period. Proteins and peptides are critical therapeutic agents used for the treatment of chronic and rare diseases. However, their oral administration has historically been limited due to low bioavailability, instability in the gastrointestinal tract, and rapid degradation. Recent advancements in formulation technologies and innovative delivery platforms are changing this landscape, unlocking significant opportunities for pharmaceutical companies.

The increasing prevalence of chronic diseases such as diabetes, cancer, and hormonal disorders has boosted the demand for protein and peptide-based therapies. Patients are increasingly seeking alternatives to injections and infusions, creating a strong push for oral dosage forms that offer greater convenience, compliance, and improved patient quality of life. Pharmaceutical companies and research organizations are investing heavily in novel delivery mechanisms to enhance the stability and absorption of these therapeutics, further driving market expansion.

Market Dynamics

The oral proteins and peptides market is influenced by a combination of growth drivers, restraints, and opportunities:
