Solution Overview

Problem

Current 3D printed medications face challenges with limited oral bioavailability due to inadequate aqueous solubility and dissolution rates, leading to significant drug loss during absorption, particularly for active pharmaceutical ingredients that do not reach commercialization.

Innovation Solution

A self-nanoemulsifying 3D printer ink composition incorporating glimepiride and rosuvastatin in a curcuma oil-based self-nanoemulsifying drug delivery system (SNEDDS) with specific surfactants, co-surfactants, and hydroxypropyl methylcellulose as a gelling agent, allowing for customizable drug release rates and enhanced bioavailability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional 3D printed medications are used, then manufacturing flexibility and personalization are improved, but oral bioavailability deteriorates due to inadequate aqueous solubility and dissolution rates

Engineering Contradiction:
ImprovepersonalizationVSAvoidoral bioavailability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent changes the physical and chemical parameters of the drug delivery system by incorporating SNEDDS technology, which transforms the drug formulation into a self-nanoemulsifying system. This changes the dissolution behavior and enhances aqueous solubility, thereby improving oral bioavailability while maintaining 3D printing personalization capabilities

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials by combining curcuma oil with specific surfactants (Tween 80, Span 60) and co-surfactants (PEG 400, PEG 200) to create a SNEDDS system. This composite formulation enhances drug solubility and dissolution rate, resolving the bioavailability issue while preserving the advantages of 3D printed personalized medication

Inventive Principle:
Principle #40Composite materials

2Reliability

If SNEDDS system is incorporated to improve bioavailability, then aqueous solubility and dissolution rates are improved, but formulation complexity increases

Engineering Contradiction:
Improveoral bioavailabilityVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The SNEDDS system is designed to be self-nanoemulsifying, meaning it automatically forms nanoemulsions upon contact with aqueous fluids in the body without requiring external energy input or complex delivery mechanisms. This self-service property simplifies the overall system while enhancing bioavailability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent utilizes phase transition phenomena where the oil-surfactant-co-surfactant mixture transitions from a macroemulsion or separate phases to a stable nanoemulsion system. This phase transition occurs spontaneously under mild conditions, enhancing drug solubility without requiring complex formulation processes

Inventive Principle:
Principle #36Phase transitions

3Adaptability or versatility

If compartmentalized tablet structure is used for personalized drug release, then dose customization is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvedose customizationVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent divides the tablet into multiple compartments or layers, each containing different drugs or dosages. This segmentation allows for personalized dose customization while using 3D printing technology to manufacture the complex structure in a relatively simple, additive process

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions or compartments of the tablet are assigned different properties, such as varying drug concentrations, release rates, or compositions. This local quality approach enables personalized medication where each compartment is optimized for specific therapeutic needs, achieved through 3D printing's layer-by-layer construction capability

Inventive Principle:
Principle #3Local quality
