Solution Overview

Problem

Current pharmaceutical formulations of cannabidiol (CBD) for peroral administration suffer from low and unpredictable bioavailability due to its lipophilic nature and susceptibility to first-pass liver metabolization, as well as instability, making them unsuitable for effective treatment of psychosis and anxiety disorders.

Innovation Solution

Development of compressed tablets containing a CBD-containing granulate with lactose and sucrose fatty acid mono-ester, where the granulate is produced by combining CBD with lactose and sucrose fatty acid mono-ester in an organic solvent, followed by evaporation and mixing with additional lactose and excipients for compression, enhancing bioavailability and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If CBD is administered perorally in conventional formulations, then it can be taken orally, but bioavailability is low and unpredictable due to poor solubility and first-pass metabolism

Engineering Contradiction:
ImprovebioavailabilityVSAvoidfirst-pass liver metabolization
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses sucrose fatty acid mono-ester as an intermediary substance that forms a complex with CBD. This complex acts as a mediator that protects CBD from first-pass metabolism and enhances its solubility in the gastrointestinal environment, thereby improving bioavailability and reducing susceptibility to liver metabolization.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention creates a composite granulate consisting of CBD, sucrose fatty acid mono-ester, and lactose. This composite material combines the lipophilic CBD with hydrophilic excipients and solubility-enhancing agents, forming a formulation that overcomes the inherent solubility problems of pure CBD and improves its absorption profile.

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If CBD is formulated for peroral administration, then oral treatment is possible, but stability is poor leading to degradation during storage

Engineering Contradiction:
Improveperoral administrationVSAvoidstability during storage
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

Sucrose fatty acid mono-ester serves as a protective intermediary that stabilizes CBD during storage. The complex formation between CBD and sucrose fatty acid mono-ester protects the cannabinoid from degradation, maintaining compositional stability while enabling peroral administration.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The composite granulate formulation with CBD, sucrose fatty acid mono-ester, and lactose creates a stable matrix that protects CBD from environmental factors during storage, preventing degradation while maintaining the desired oral dosage form.

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If conventional CBD formulations are used, then they are simple to manufacture, but bioavailability remains low and unpredictable

Engineering Contradiction:
Improveformulation simplicityVSAvoidbioavailability predictability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent employs a composite granulate formulation that combines CBD with sucrose fatty acid mono-ester and lactose in specific proportions. This composite approach maintains manufacturing simplicity through conventional granulation and compression techniques while significantly improving bioavailability predictability through the solubility-enhancing and metabolism-protecting effects of the composite materials.

Inventive Principle:
Principle #40Composite materials
