Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ginkgo terpene lactone is formulated as an ordinary oral preparation, then the drug can be administered conveniently, but the bioavailability is limited and clinical efficacy is reduced
Solution Approach 1:
The patent employs porous silica gel as a carrier material to load ginkgo terpene lactone. The porous structure provides high surface area and porosity, enabling enhanced drug loading capacity and controlled release, thereby improving bioavailability while maintaining formulation feasibility
Solution Approach 2:
The patent creates a composite formulation combining ginkgo terpene lactone with porous silica gel and other excipients. This composite structure leverages the adsorption properties of silica gel and the pharmacological activity of the active ingredient, achieving improved bioavailability through material synergism
2Quantity of substance
If ginkgo terpene lactone is formulated with increased drug loading, then the therapeutic effect is enhanced, but the dissolution rate becomes limited
Solution Approach 1:
The porous silica gel carrier provides a high surface area matrix that accommodates increased drug loading while maintaining rapid dissolution through its porous structure. The pores facilitate quick drug release into the dissolution medium, resolving the trade-off between loading capacity and dissolution rate
Solution Approach 2:
The patent modifies the physical parameters of the formulation by using porous materials with specific pore sizes and surface areas. This changes the dissolution kinetics by increasing the surface area to volume ratio, enabling both high drug loading and rapid dissolution simultaneously
