Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compound (I) has very poor solubility in water, leading to low drug oral availability in common dosage forms, and conventional emulsions are not well accepted due to their large volume, short shelf life, and poor palatability.
Innovation Solution
A self-emulsifying pharmaceutical composition comprising Compound (I), an oil phase, an emulsifier, and a co-emulsifier, with specific weight ratios, forming a stable self-emulsifying preparation that can be prepared into oral liquids, capsules, or tablets, improving solubility and oral bioavailability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional emulsion dosage forms are used to improve drug solubility, then solubility is improved, but volume is large and shelf life is short
Solution Approach 1:
The patent changes the physical and chemical parameters of the emulsion system by using specific oil phases (medium-chain triglycerides, monocaprylin, dicaprylin), emulsifiers (polyoxyl-40 hydrogenated castor oil, tocopherol polyethylene glycol succinate, polyoxyl-15 hydroxystearate, polyoxyl-35 castor oil), and co-emulsifiers (polyethylene glycol 400, diethylene glycol monoethyl ether) in optimized ratios to create a self-emulsifying preparation that maintains stability while improving solubility
Solution Approach 2:
The patent creates a composite self-emulsifying preparation system combining multiple components: Compound (I) as the active ingredient, oil phase as the solvent, emulsifier for stabilization, and co-emulsifier for enhanced solubility. This composite approach resolves the contradiction by integrating functions of solubility enhancement and shelf life extension into a single stable formulation
2Quantity of substance
If conventional emulsion dosage forms are used to improve drug solubility, then solubility is improved, but palatability is poor
Solution Approach 1:
The patent modifies the sensory parameters of the formulation by selecting oil phases with pleasant tastes (medium-chain triglycerides, monocaprylin, dicaprylin) and emulsifiers with good palatability (polyoxyl-40 hydrogenated castor oil, tocopherol polyethylene glycol succinate), transforming the harmful effect of poor palatability into a beneficial patient-friendly formulation
3Ease of manufacture
If common dosage forms are used for Compound (I), then manufacturing is simple, but oral bioavailability is low
Solution Approach 1:
The patent creates a self-emulsifying preparation that automatically forms emulsions upon contact with gastrointestinal fluids without requiring external emulsification equipment or complex manufacturing processes. The preparation contains all necessary components (oil phase, emulsifier, co-emulsifier) that self-assemble into emulsion droplets, achieving high oral bioavailability while maintaining manufacturing simplicity
Solution Approach 2:
The patent changes the physical state and composition parameters of the dosage form by incorporating specific ratios of oil phase (10-20 parts), emulsifier (50-65 parts), and co-emulsifier (20-30 parts) to create a self-emulsifying system that enhances oral bioavailability through improved drug dissolution and absorption
