This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,531.

Summary of the Inventive Concept

This inventive concept leverages the core technology of mast cell inhibition to treat various skin conditions, including atopic dermatitis, rosacea, and allergic contact dermatitis, offering a new paradigm for reducing inflammation and promoting healing.

Background and Problem Solved

The original patent focused on treating benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) using combination mast cell inhibition and histamine receptor antagonism. However, skin conditions such as atopic dermatitis, rosacea, and allergic contact dermatitis remain significant unmet medical needs, with limited effective treatments available. The new inventive concept addresses this gap by applying the core technology to these skin conditions, providing a novel solution for reducing inflammation and promoting healing.

Detailed Description of the Inventive Concept

The new inventive concept involves the use of mast cell inhibitors, such as cromolyn sodium, and histamine receptor antagonists, in combination, to treat skin conditions. The mast cell inhibitor is applied topically to the affected skin area, reducing inflammation and promoting healing. The histamine receptor antagonist enhances the therapeutic effect by blocking histamine receptors, which are involved in the inflammatory response. The combination therapy can be formulated for topical administration, providing a convenient and effective treatment option for patients. In the context of atopic dermatitis, the combination therapy reduces inflammation and itching, improving the quality of life for patients. In rosacea, the combination therapy reduces inflammation and redness, providing a more effective treatment option. In allergic contact dermatitis, the combination therapy reduces inflammation and itching caused by allergic reactions, offering a novel solution for this common condition.

Novelty and Inventive Step

The new inventive concept is novel and non-obvious compared to the original patent, as it applies the core technology to entirely new applications, including skin conditions. The combination of mast cell inhibition and histamine receptor antagonism for treating skin conditions is unexpected and provides a new paradigm for reducing inflammation and promoting healing.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different mast cell inhibitors, such as ketotifen, or different histamine receptor antagonists, such as loratadine. Additionally, the combination therapy could be formulated for oral administration, providing a systemic treatment option for patients with severe skin conditions. Other variations could include the use of additional therapeutic agents, such as corticosteroids or immunomodulators, to enhance the therapeutic effect.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential, as it addresses a large and growing market for skin condition treatments. The global market for atopic dermatitis treatments is projected to reach $18.3 billion by 2025, while the market for rosacea treatments is expected to reach $2.5 billion by 2027. The inventive concept could be developed and commercialized by pharmaceutical companies, providing a new revenue stream and expanding their product portfolios.
