DKSH Solutions for Mucosal Drug Delivery & Protection: Advanced Ingredients & Formulation Support for Pharma Applications
Mucosal drug delivery is gaining increasing attention in pharmaceutical development due to its potential for local therapeutic action, rapid onset, and improved patient compliance.
Across therapeutic areas such as ophthalmology, nasal allergy, respiratory care, and women’s health. Pharmaceutical companies are actively searching for mucosal-friendly excipients, barrier-protecting ingredients, and formulation strategies that enhance both efficacy and patient comfort.
However, mucosal tissues are inherently sensitive. Developing effective mucosal formulations requires a careful balance between efficacy, stability, and patient comfort, making formulation design particularly complex.
What Is Mucosal Protection in Drug Delivery?
Mucosal protection in drug delivery refers to formulation strategies that help maintain or support the integrity of mucosal tissues during product use.
Mucosal surfaces such as nasal, ocular, vaginal, and respiratory linings are exposed to mechanical stress, environmental factors, and formulation components that may cause irritation or dehydration.
As a result, protecting the mucosal barrier is increasingly viewed as an integral part of formulation performance rather than an optional feature.
DKSH’s Formulation-Driven Approach
DKSH supports pharmaceutical companies by offering a range of ingredients used in the formulation of mucosal protection products, enabling a formulation-driven approach.
Rather than focusing on a single ingredient or function, DKSH brings together complementary formulation components that address different requirements of mucosal systems. This approach allows formulators to design balanced and adaptable formulations across multiple dosage forms and indications.
By supporting formulation design at a system level, DKSH helps customers address both technical performance and patient experience. 
Key Ingredients for Mucosal Drug Delivery Formulations
Effective mucosal formulations typically rely on multiple functional elements. DKSH’s portfolio includes ingredients that support:
- Mucosal Protection: Ingredients that help stabilize and protect mucosal tissues, particularly in formulations intended for frequent or long-term use.
- Drug Dispersion Enhancers: Non-ionic surfactants (e.g. Tyloxapol) used to promote uniform API distribution while maintaining acceptable tolerability profiles.
- Solubilization: Excipients that enhance API solubility and delivery, especially for poorly soluble active ingredients.
- Hydration and Mucoadhesion: Humectants and polymers such as glycerol and HPMC that support moisture retention and prolonged residence time on mucosal surfaces.
- Formulation Stability: Components that contribute to physical and chemical robustness in aqueous and semi-solid systems.
Together, these building blocks allow formulators to address multiple challenges simultaneously instead of optimizing individual parameters in isolation.
Applications of Mucosal Drug Delivery
DKSH’s formulation solutions are applicable across a wide range of pharmaceutical segments:
- Ophthalmic formulations (e.g. dry eye formulations)
- Nasal drug delivery systems (allergy & congestion relief)
- Respiratory therapies ( inhalation & airway hydration)
- Women’s intimate care products
Each application requires customized formulation strategies due to differences in physiology, sensitivity, and regulatory pathways.
Example: Osmoprotective Ingredients for Mucosal Protection
Osmoprotective molecules such as medEctoin® are widely used in mucosal formulations to support barrier protection and hydration.
These ingredients support mucosal protection through physical mechanisms, such as membrane stabilization via preferential hydration, helping to reduce irritation and support mucosal integrity.
This makes them suitable for ophthalmic, nasal, and respiratory applications, particularly where long-term tolerability is essential.
Key Formulation and Regulatory Considerations
When developing mucosal drug delivery products, formulators should consider:
- Compatibility between APIs and excipients
- pH and osmolality alignment with mucosal physiology
- Stability in aqueous and semi-solid dosage forms
- Intended regulatory classification (drug or medical device), depending on claims and indication
DKSH supports customers with technical documentation and formulation guidance throughout development.
Why Mucosal Drug Delivery Is Growing in Pharma
Mucosal drug delivery is gaining traction because it offers:
- Faster onset of action
- Non-invasive administration
- Improved patient adherence
- Targeted therapeutic effects
As pharmaceutical innovation continues, mucosal protection and delivery optimization will remain critical for product success and differentiation.

1. What is mucosal drug delivery and why is it important?
: Mucosal drug delivery involves administering drugs through mucous membranes such as nasal, ocular, or respiratory tissues. It is important because it enables rapid absorption, localized treatment, and improved patient compliance while avoiding first-pass metabolism.
2. How can mucosal barriers be protected in drug formulations?
: Mucosal barriers can be protected by using osmoprotective agents, humectants, and mild excipients that maintain hydration and reduce irritation. Optimizing pH and osmolality is also critical to preserving mucosal integrity.
3. Which excipients are commonly used in mucosal drug delivery formulations?
: Common excipients include mucoadhesive polymers like HPMC, humectants such as glycerol, surfactants like Tyloxapol, and solubilizers. These help improve drug stability, enhance absorption, and ensure better tolerability.
4. How do you improve drug absorption in mucosal delivery systems?
: Drug absorption can be improved by increasing residence time using mucoadhesive polymers, enhancing API solubility, and optimizing formulation parameters such as pH and tonicity to match physiological conditions.
5. Why do mucosal formulations sometimes cause irritation?
: Irritation can occur due to non-physiological pH, high osmolality, or harsh excipients. Lack of proper hydration or protective ingredients may also compromise the mucosal barrier and lead to discomfort.
6. How does DKSH support mucosal drug delivery formulation?
: DKSH supports pharmaceutical companies by offering a portfolio of functional excipients, formulation expertise, and technical guidance to develop stable, effective, and patient-friendly mucosal products.
