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. 11,857,684.

Summary of the Inventive Concept

A novel, multi-layered tablet design that integrates sequential release of active pharmaceutical ingredients, pH-dependent coatings, and companion diagnostic devices for personalized medicine, offering improved efficacy and patient outcomes.

Background and Problem Solved

The original patent disclosed bilayer tablets comprising acetylsalicylic acid and pseudoephedrine. However, these tablets have limitations in terms of release profiles, dissolution rates, and patient-specific dosing. The new inventive concept addresses these limitations by introducing a multi-layered design, advanced manufacturing techniques, and integrated diagnostic devices.

Detailed Description of the Inventive Concept

The next-generation bilayer tablets comprise three layers: a first layer containing acetylsalicylic acid and pseudoephedrine, a second layer containing a dissolution aid, and a third layer featuring a pH-dependent coating. This design enables sequential release of the active pharmaceutical ingredients, providing rapid relief from symptoms and sustained therapeutic effects. The tablets are manufactured using a novel combination of 3D printing and hot-melt extrusion techniques, allowing for complex geometries and customized release profiles. Furthermore, the tablets are paired with a companion diagnostic device that provides real-time feedback on an individual's response to the active pharmaceutical ingredients, enabling personalized dosing and treatment regimens.

Novelty and Inventive Step

The new claims introduce a paradigm shift in bilayer tablet design, manufacturing, and functionality. The multi-layered design, advanced manufacturing techniques, and integrated diagnostic devices provide a novel and non-obvious solution that significantly improves upon the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include tablets with varying layer compositions, geometries, and release profiles tailored to specific patient populations or disease indications. Additionally, the diagnostic device could be integrated with artificial intelligence and machine learning algorithms to optimize treatment outcomes and predict patient responses.

Potential Commercial Applications and Market

The next-generation bilayer tablets have significant commercial potential in the pharmaceutical industry, particularly in the areas of personalized medicine, respiratory health, and pain management. The integrated diagnostic device and advanced manufacturing techniques offer a competitive advantage in the market, with potential applications in hospital settings, clinical trials, and direct-to-consumer sales.
