Mucosaalapú

Mucosaalapú approaches refer to strategies that target mucosal surfaces, the moist linings of the body such as the gastrointestinal, respiratory, and reproductive tracts, as well as the oral cavity. The term is used in pharmacology, vaccinology, and biomaterials to describe formulations and devices designed to interact with mucus and mucosal tissues rather than relying solely on systemic routes.

Mucosal surfaces serve as barriers and immunological sites. They provide a large surface area and access to local tissues, enabling both mucosal and systemic immune responses. Challenges include the mucus layer, enzymatic activity, variable pH, and rapid mucociliary clearance, which can reduce stability and residence time of administered agents.

To address these barriers, researchers use mucoadhesive polymers, permeation enhancers, and carrier systems such as nanoparticles, liposomes, and hydrogels. These are employed in oral, nasal, buccal/sublingual, vaginal, and rectal delivery, as well as ocular and other mucosal routes. Some formulations aim to stimulate mucosal immunity, while others seek local or systemic effects.

Applications include mucosaalapú vaccines that induce mucosal IgA responses and systemic immunity, mucosaalapú drug delivery for analgesia or local therapy, and diagnostic tools that sample mucosal secretions for biomarkers.

Advantages include non-invasive administration, potential for rapid onset, and improved patient acceptance. Limitations involve formulation stability, interindividual variability, the risk of irritation or tolerance, and regulatory complexity for mucosal products.

Research focuses on materials, delivery devices, and regulatory pathways to advance mucosaalapú strategies while ensuring safety and efficacy.
