Solution Overview

Problem

Current oral formulations of T4 thyroid hormone are inconvenient due to their dependence on meal timing, leading to reduced gastrointestinal absorption and compliance issues, as they require administration before meals or at specific times, which can disrupt daily routines and result in variable therapeutic effects.

Innovation Solution

An alcohol-free, water-glycerol solution of T4 thyroid hormone is administered within 30 minutes of a meal, allowing for flexible timing and maintaining high absorption rates, independent of food intake, thereby reducing interference with daily routines and ensuring consistent blood levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If T4 thyroid hormone is administered orally in conventional formulations, then the treatment is convenient and can continue throughout the patient's life, but the absorption is reduced when administered close to meals due to food interference and reduced gastric acidity

Engineering Contradiction:
Improveconvenience of administrationVSAvoidabsorption consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent changes the physical-chemical parameters of the T4 formulation by using alcohol-free water-glycerol solutions with specific pH control and glycerol concentrations (1-50% w/v). These parameter changes enable the formulation to maintain stable absorption (within 80-120% of fasting conditions) when administered within 30 minutes of meals, overcoming the traditional constraint that required administration 3-4 hours before or after meals.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If T4 is administered before meals to ensure proper absorption, then absorption is improved, but the administration disrupts daily routines and reduces patient compliance

Engineering Contradiction:
Improveabsorption efficiencyVSAvoidcompliance with daily routine
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent inverts the traditional administration paradigm by eliminating the need for fasting conditions. Instead of requiring patients to adjust their meal times to accommodate medication administration, the formulation allows patients to take T4 with or near meals without significant absorption reduction, thereby integrating treatment into rather than disrupting daily routines.

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If alcohol is added to T4 formulations to enhance dissolution and absorption, then bioavailability is improved, but the formulation becomes less suitable for patients who avoid alcohol

Engineering Contradiction:
ImprovebioavailabilityVSAvoidsuitability for all patients
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent extracts and eliminates alcohol from the T4 formulation while maintaining or improving absorption characteristics. By removing the alcohol component and replacing it with water-glycerol solutions, the formulation becomes suitable for all patients including those who avoid alcohol, while still achieving high bioavailability through optimized solubility and gastric retention properties.

Inventive Principle:
Principle #2Taking out (Extraction)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This solution enables reproducible and higher blood levels of T4 with minimal influence from food cycles, improving compliance and therapeutic effectiveness by allowing administration closer to meals without significant absorption reduction.

AI summary

New administration regimens of the T4 thyroid hormone are described, characterized by the use of alcohol-free, water-glycerol solutions of said hormone, administered at short temporal distance, i.e. within less than 30 minutes, typically between 15 and less than 30 minutes, from the closest consumed meal.
