The global xerostomia (dry mouth disease) therapeutics market size was valued at USD 763.03 Million in 2024. Looking forward, IMARC Group estimates the market to reach USD 1,007.31 Million by 2033, exhibiting a CAGR of 2.98% from 2025-2033. North America currently dominates the market, holding a market share of over 36.8% in 2024, attributed to a well-established healthcare system, increased disease understanding, and growing incidence of dry mouth due to the elderly population and medications.

The xerostomia (dry mouth disease) therapeutics market expands due to rising incidence of dry mouth conditions, involving Sjogren's syndrome, diabetes, and radiation therapy for cancer patients. The effective treatment demand is witnessing a notable increase with lung cancer and an aging population. Additionally, healthcare professionals alongside patients are increasingly aware of dry mouth disease which drives their pursuit of therapeutic solutions. Moreover, improved drug formulations, including secretagogues and saliva substitutes, profilerating the market forward as these new formulations provide better effectiveness and comfort to patients. Technological advances in drug delivery systems with emphasis on personalized medicine also contribute to the market's growth.

In the United States, the xerostomia therapeutics market is growing with a high incidence of risk factors like aging, diabetes, and cancer therapy, especially head and neck radiation. The increasing use of targeted therapies and technological advancements in over-the-counter products are offering increased treatment choices for patients. For instance, as per industry reports, researchers from University of Wisconsin School of Medicine Public Health, in partnership with PACT, is performing a clinical trial to explore the potential of using a patient's own enhanced stem cells to improve salivary gland function in Sjogren's disease. This innovative approach involves extracting stem cells from the patient's bone marrow, activating them, and injecting them into the salivary glands. Furthermore, as the understanding of xerostomia's impact on health continues to evolve, demand for effective and accessible treatments in the U.S. is expected to rise steadily.

Xerostomia (Dry Mouth Disease) Therapeutics Market Trends:

Advancements in Salivary Stimulant Formulations

The xerostomia therapeutics market has some of the most significant advancements in the formulation of salivary stimulants. The demand for prolonged and effective treatment is, however, driving these changes. Most of the classical saliva substitutes provide only temporary relief, forcing researchers to seek newer or innovative drug delivery methods like mucoadhesive formulations, sustained-release gels, and nanoparticle-based therapies. Companies have also turned their attention to plant-derived compounds or regenerative medicine approaches to stimulate rather than replace this natural saliva production capability. Biologics are being developed targeting salivary gland function, like growth factors and gene therapy, that might offer some long-term benefits. This development improves patient compliance and the efficacy of the treatment through improved moisture retention and decreased frequency of reapplication. Prescription-based formulations with enhanced bioavailability further add to the market's growth. With over 30% of individuals aged 65 and older experiencing dry mouth, there is a growing need for innovative solutions that improve patient compliance and offer sustained relief, a research article stated. As a consequence, the industry is moving away from symptomatic relief products towards therapeutic interventions targeting the cause of dry mouth. This will ensure better patient outcomes.

Growing Adoption of Prescription Therapies Over OTC Products

The market of xerostomia therapeutics is moving away from OTC dry mouth relief products to more prescription-based drugs based on the increasing awareness within the healthcare professional community and the patients' concern for complete long-term management. While OTC products such as artificial saliva sprays, lozenges, or mouth rinses provide mere symptom relief, it does not take into account the root causes of the dryness. On the other hand, prescription medications such as pilocarpine and cevimeline, muscarinic receptor agonists stimulate salivary gland function to produce long-lasting effects. In addition, promising drug candidates for clinical development involve enhancement of saliva flow and glandular regeneration that positions prescription treatments as a more viable option. The healthcare provider has increasingly become recommending prescription treatments to patients who suffer from chronic xerostomia secondary to Sjogren's syndrome, radiation therapy, or polypharmacy-induced dryness. This shift is expected to fuel market growth as pharmaceutical companies continue investing in the development of targeted treatments with improved efficacy and safety profiles. Studies suggest that up to 73.4% of patients undergoing chemotherapy report experiencing xerostomia, with the prevalence rising to 90% among those receiving radiation therapy for head and neck cancers. This trend is driving the adoption of prescription-based treatments targeting the underlying pathology.

Rising Prevalence of Xerostomia Due to Chronic Diseases and Medications

The principal reason for the rising rate of xerostomia cases is the increased number of chronic diseases and side effects from medication. Diseases like diabetes, Sjogren's syndrome, and other autoimmune diseases have a direct impact on salivary glands, causing symptoms of xerostomia to be felt for long durations. Similarly, cancer treatments through radiation therapy and chemotherapy often damage salivary glands, thereby resulting in xerostomia as a common side effect in cancer patients. Studies indicate that xerostomia affects 13-17% of the general population, with prevalence rates rising to 30-40% among the elderly due to polypharmacy. The widespread use of medications such as antihypertensives, antidepressants, and opioids further contributes to the rising number of cases, with over 400 commonly prescribed drugs known to cause dry mouth as a side effect. Demand for effective remedies against xerostomia will increase among the aging globe and the constantly growing burden of chronic diseases. As such, pharmaceutical companies are coming forward with the drugs that can offer symptomatic relief and address the underlying cause of dry mouth. The rising number of patients, thus, represents an important area for innovation and growth in the xerostomia therapeutics market.
