Solution Overview

Problem

Existing formulations for delivering Cannabaceae derivatives, nicotine, and caffeine face challenges such as first-pass hepatic metabolism and variable absorption when administered orally, and existing lip balms lack effective surfactants for rapid delivery.

Innovation Solution

A lip balm formulation containing greater than 10 wt.% surfactant, with a lipid-to-surfactant ratio of 3/1 to 1/3, delivering Cannabaceae derivatives, nicotine, or caffeine topically, without an aqueous phase, ensuring rapid absorption in less than a minute.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If oral administration of A9-THC is used, then the drug can be delivered systemically, but first-pass hepatic metabolism reduces the amount reaching circulation to only 10-20%

Engineering Contradiction:
Improveamount of A9-THC reaching systemic circulationVSAvoidloss of A9-THC due to first-pass metabolism
Core Design Contradiction:
Quantity of substanceVSLoss of energy

Solution Approach 1:

The invention extracts A9-THC from the oral administration route and delivers it directly to the systemic circulation through transdermal application, bypassing the gastrointestinal tract and liver metabolism. The lip balm formulation allows A9-THC to be absorbed through the lip mucosa directly into the bloodstream, eliminating the first-pass metabolic loss.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The lip balm formulation acts as an intermediary delivery system that facilitates direct transfer of A9-THC from the application site to the systemic circulation. The formulation includes penetration enhancers and lipids that mediate the transport of A9-THC through the lip mucosa, enabling efficient delivery without oral metabolism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If oral capsules are used for A9-THC delivery, then the drug can be administered conveniently, but absorption shows large inter-subject variability

Engineering Contradiction:
Improveconsistency of A9-THC absorptionVSAvoidvariability in absorption among different subjects
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The invention applies A9-THC locally to the lip mucosa, which has consistent physiological properties across different individuals. The lip tissue provides a uniform absorption interface, eliminating the variability associated with oral administration that depends on individual gastrointestinal factors, food intake, and hepatic metabolism.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention changes the administration parameter from oral to transdermal (lip mucosa), fundamentally altering the absorption pathway. This parameter change standardizes the delivery route across all users, eliminating inter-subject variability in absorption while maintaining convenient administration.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If conventional lip balms without surfactants are used, then the formulation remains simple, but delivery of A9-THC is slow and ineffective

Engineering Contradiction:
Improverate of A9-THC deliveryVSAvoidcomplexity of lip balm formulation
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Surfactants and penetration enhancers are introduced as intermediary substances that facilitate the rapid delivery of A9-THC through the lip mucosa. These agents mediate the interaction between the A9-THC and the biological membrane, enabling efficient penetration without requiring complex delivery systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The lip balm formulation uses composite materials combining lipids, surfactants, and penetration enhancers to create an effective delivery system. This composite approach enables rapid A9-THC delivery while maintaining a relatively simple overall formulation structure.

Inventive Principle:
Principle #40Composite materials

4Speed

If A9-THC is administered in sesame oil capsules, then the drug can be delivered orally, but the onset of action is delayed to 0.5-1 hour

Engineering Contradiction:
Improveonset of action of A9-THCVSAvoidtime delay before A9-THC takes effect
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The invention extracts A9-THC from the delayed oral capsule delivery system and implements direct transdermal delivery through the lip mucosa. This eliminates the dissolution and absorption delays inherent in oral capsule administration, achieving immediate onset of action.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The lip balm formulation is pre-prepared with A9-THC in a delivery-optimized matrix containing penetration enhancers. When applied to the lips, the formulation immediately begins facilitating A9-THC absorption, eliminating the lag time required for oral capsule dissolution and gastrointestinal absorption.

Inventive Principle:
Principle #10Preliminary action
