Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Curcumin's low bioavailability, poor aqueous solubility, instability at neutral and basic pH, poor absorption, rapid metabolism, and short half-life limit its therapeutic use for treating conditions like osteoarthritis.
Innovation Solution
Development of stable curcumin formulations comprising curcuminoids in different polymorphic forms like amorphous and crystalline, with specific ratios, and optionally with pharmaceutically/nutraceutically accepted excipients such as hydrophilic carriers, antioxidants, and pH modifiers, to enhance absorption and bioavailability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If curcumin is used in its natural form, then it provides anti-inflammatory and therapeutic effects, but it exhibits low bioavailability, poor aqueous solubility, and instability at neutral and basic pH
Solution Approach 1:
The patent changes the physical and chemical parameters of curcumin by converting it between crystalline and amorphous forms. The amorphous form exhibits enhanced solubility and bioavailability compared to the crystalline form, while the specific polymorphic composition maintains stability in physiological pH conditions. This parameter change resolves the contradiction between therapeutic effectiveness and stability.
Solution Approach 2:
The invention creates a composite curcumin formulation containing curcumin in specific polymorphic forms (amorphous and crystalline) combined with excipients such as hydrophilic carriers, antioxidants, and pH modifiers. This composite structure enhances both the stability at neutral/basic pH and the bioavailability, while maintaining the therapeutic anti-inflammatory effects of curcumin.
2Reliability
If curcumin is administered orally, then it provides systemic therapeutic effects, but it exhibits poor absorption and rapid metabolism
Solution Approach 1:
The patent utilizes parameter changes by transforming curcumin into amorphous polymorphic form, which has superior solubility and dissolution characteristics compared to crystalline form. This physical state change enhances intestinal absorption and reduces first-pass metabolism, thereby improving oral bioavailability while maintaining systemic therapeutic effects.
Solution Approach 2:
The invention introduces excipients as intermediaries, including hydrophilic carriers, solubilizers, and absorption enhancers, that facilitate the dissolution and absorption of curcumin in the gastrointestinal tract. These intermediary substances protect curcumin from rapid metabolism and improve its transport across biological membranes, enabling effective oral delivery.
3Reliability
If curcumin is used to treat osteoarthritis, then it reduces inflammation and improves joint mobility, but it has short half-life and requires frequent administration
Solution Approach 1:
The patent applies preliminary action by pre-formulating curcumin in stable amorphous and crystalline polymorphic forms with enhanced bioavailability before administration. This pre-preparation ensures optimal dissolution and absorption in the gastrointestinal tract, leading to sustained plasma concentrations and prolonged half-life, thereby reducing the frequency of administration while maintaining anti-inflammatory effects.
Solution Approach 2:
The invention uses partial action by incorporating specific ratios of amorphous and crystalline curcumin polymorphs, along with excipients, to achieve sustained release and prolonged circulation. This compositional approach extends the half-life of curcumin in the body, allowing less frequent dosing while maintaining therapeutic anti-inflammatory levels.

AI summary
The present invention relates to a stable curcumin composition for prevention improvement and maintenance of arthritis more particularly to osteoarthritis. The stable curcumin composition is comprised of curcuminoids either alone or along with at least one pharmaceutically and/or nutraceutically accepted excipient to form the stable curcumin compositions having enhancement in absorption and bioavailability. The composition is safe for consumption, possess enhanced stability and bioavailability due to selective percentage of amorphous and crystalline polymorphic form of curcumin along with selective excipient such as pH modifier and/or stabilizer and optionally hydrophilic carrier, antioxidant, diluents, anticaking agent, emulsifier, fat and surfactant which result in improvement of symptoms of arthritis and associated conditions, when administered to subjects, in need thereof.
