Solution Overview

Problem

Poorly soluble drugs and nutraceuticals, such as tocotrienols (T3s), suffer from low bioavailability and variable efficacy due to limited absorption and metabolic issues, hindering their therapeutic potential.

Innovation Solution

A self-emulsifying solid dispersion (SESD) composition comprising a drug or nutraceutical, a surfactant, a carrier (silicic acid or silicate), and a carbohydrate filler, which enhances solubility and bioavailability by forming a self-emulsifying solid dispersion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If poorly soluble drugs or nutraceuticals are administered orally, then they can be delivered to the body, but their bioavailability is low due to poor solubility and absorption

Engineering Contradiction:

ImprovebioavailabilityVSAvoidsolubility

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies composite materials by formulating a self-emulsifying solid dispersion (SESD) composition that combines poorly soluble drug or nutraceutical with surfactants, carriers, and fillers. This composite system enables the hydrophobic active ingredient to form stable emulsions in aqueous environments, thereby improving solubility and bioavailability without altering the drug molecule itself

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent employs parameter changes by modifying the physical state and surface properties of the poorly soluble drug through interaction with surfactants and carriers in the SESD formulation. The surfactants reduce interfacial tension and the carriers provide a hydrophilic matrix, collectively changing the solubility parameters to enable better aqueous dispersion and absorption

Inventive Principle:

Principle #35Parameter changes

2Reliability

If conventional formulations are used for hydrophobic drugs, then manufacturing is simple, but absorption and therapeutic efficacy are limited

Engineering Contradiction:

Improvetherapeutic efficacyVSAvoidformulation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies self-service through the self-emulsifying property of the SESD formulation. Upon contact with gastrointestinal fluids, the formulation automatically forms stable emulsions without requiring external emulsification equipment or complex processing steps, thereby improving therapeutic efficacy while maintaining relatively simple manufacturing

Inventive Principle:

Principle #25Self-service
