Oral Immunostimulant Market - Growth Drivers and Challenges

Growth Drivers

  • Increasing awareness about oral immunostimulants - Pharmaceutical and healthcare organizations conduct campaigns to educate the public about the benefits of oral immunostimulants, their mechanisms, and their positive impact on overall health.

    Moreover, the creation and distribution of educational material including brochures, pamphlets, and digital content that explains the science behind oral immunostimulants and their role in supporting the immune system will boost the market.
  • Emergence of technological advancement - Technological advancement contributes to the formulation, delivery, and overall efficacy of oral immunostimulants. Additionally, rising healthcare spend also contributes to the market growth. According to a recent report, global spending on health reached USD 9.8 trillion or 10.3% of the global domestic product (GDP) in 2021. 

    The use of nanotechnology enables the creation of nanoparticles that improve the solubility of immunostimulants, facilitate better absorption, and enhance overall effectiveness. In addition, the integration of genetic engineering and recombinant DNA technology enables the production of oral immunostimulants with improved purity and consistency.
  • Aging population more susceptible to infections - As people age, their immune system naturally weakens. This weakening makes older adults more susceptible to infections, and diseases, thereby increasing the need for interventions that boost their immune responses which increase the demand for oral immunostimulants.

    Moreover, the aging population has more chronic conditions, in this case, immunostimulants can help in managing these conditions by reducing the risk of infections and complications. Immunostimulant improves the quality of life and potentially reduce healthcare costs. Furthermore, the aging population not only represents a growing segment of the demographic but also a group with specific healthcare needs that oral immunostimulants can address.

Challenges

  • Competition from alternative therapies - There is a rise in competition from alternative therapies such as injectable immunostimulants, traditional medicines, and dietary supplements in the oral immunostimulant market. Convincing healthcare professionals and consumers about the unique benefits of oral immunostimulants can be challenging.
  • The lack of complete understanding of immune system modulation can hinder the development of targeted oral immunostimulants.
  • Regulatory agencies have stringent requirements for approving healthcare products such as oral immunostimulants which hampers the market.
