Multiphase Soft Gelatin Capsule for Statin-Omega-3 Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formulations of statins and omega-3 fatty acids in soft gelatin capsules face stability issues due to interconversion and incompatibility, leading to degradation and loss of pharmaceutical characteristics when combined in a single dosage form.
Innovation Solution
A multi-phase soft gelatin capsule design that incorporates a preformed solid dosage form of statins and a liquid omega-3 oil phase, maintaining chemical stability and preventing chemical reactions between the phases while retaining the established pharmaceutical characteristics of each component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If statins are formulated in liquid fill formulation, then ease of manufacture is improved, but stability deteriorates due to interconversion and degradation
Solution Approach 1:
The invention divides the soft gelatin capsule into multiple distinct phases: a liquid phase containing omega-3 fatty acids and a solid phase containing the statin compound. This segmentation prevents direct contact between incompatible substances, maintaining stability while enabling soft gelatin formulation. The solid statin phase is suspended in the liquid omega-3 phase without dissolving or reacting, resolving the contradiction between ease of manufacture and stability.
2Ease of operation
If statins and omega-3 oils are combined in a single dosage form, then convenience is improved, but compatibility deteriorates due to chemical reactions
Solution Approach 1:
The invention creates a multi-phase system where statins and omega-3 oils are physically separated into distinct solid and liquid phases within the same soft gelatin capsule. This segmentation maintains compatibility by preventing harmful chemical reactions while achieving the convenience of combined administration in a single dosage form.
Solution Approach 2:
The soft gelatin matrix acts as an intermediary medium that accommodates both the solid statin phase and liquid omega-3 phase. The gelatin shell provides a protective environment that prevents direct interaction between incompatible substances while allowing both components to coexist in a stable, combined dosage form, resolving the contradiction between convenience and compatibility.
3Stability of the object's composition
If preformed solid dosage form is incorporated into soft gelatin capsule, then stability is improved, but device complexity increases
Solution Approach 1:
The invention incorporates a preformed solid dosage form containing the statin compound as a distinct phase within the soft gelatin capsule. This segmentation maintains the stability advantages of solid dosage forms while integrating them into the liquid-filled soft gelatin system. The multi-phase structure achieves stability without requiring complex chemical modifications or additional stabilizing agents.
