Solution Overview

Problem

Existing pharmaceutical formulations of AG10 suffer from instability and inconsistent pharmacokinetic data, particularly when high loads of AG10 are required, leading to issues such as tablet erosion and reduced dissolution rates during extended storage.

Innovation Solution

The use of high-grade microcrystalline cellulose with spherical morphology and porous structure or needle-like particle shape, combined with specific ratios of fillers, disintegrants, and lubricants, to create tablet formulations that maintain stability and consistent pharmacokinetic profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If high loads of AG10 are used in tablet formulations, then the therapeutic efficacy is improved, but the stability of the formulation deteriorates leading to tablet erosion and reduced dissolution rates during extended storage

Engineering Contradiction:
ImproveAG10 loadVSAvoidformulation stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by modifying the physical and chemical parameters of the formulation components. Specifically, it uses high-grade microcrystalline cellulose with controlled particle size (10-50 μm) and specific surface area (1.5-3.0 m²/g), along with optimizing the ratio of excipients (microcrystalline cellulose 30-70%, colloidal silicon dioxide 1-10%, magnesium stearate 1-5%). These parameter optimizations enable the formulation to maintain stability even with high AG10 loads (60-85% w/w), resolving the contradiction between drug load and formulation stability.

Engineering Contradiction:
ImproveAG10 loadVSAvoiddissolution rate
Core Design Contradiction:
Quantity of substanceVSSpeed

Solution Approach 1:

The patent optimizes physical parameters of the excipients to maintain dissolution rate. High-grade microcrystalline cellulose with specific particle size (10-50 μm) and surface area (1.5-3.0 m²/g) provides adequate porosity and surface area for drug dissolution. The controlled pore volume (0.3-0.6 mL/g) ensures proper water penetration and drug release, allowing high AG10 loads (60-85% w/w) to maintain consistent dissolution rates even after extended storage.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite tablet formulation combining AG10 with a specific ratio of excipients: microcrystalline cellulose (30-70%), colloidal silicon dioxide (1-10%), and magnesium stearate (1-5%). This composite structure leverages the complementary properties of each component - microcrystalline cellulose provides structural integrity and porosity, silicon dioxide prevents caking and improves flow, and magnesium stearate provides lubrication. The synergistic combination enables high drug load while maintaining dissolution performance.
