Oral Liquid Herbal Formulation for Berberine Solubility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formulations of berberine for respiratory diseases face challenges in solubility, bioavailability, and stability, especially in solid oral dosage forms, and there is a need for stable syrup formulations that can combine multiple herbal extracts effectively.
Innovation Solution
A novel oral liquid pharmaceutical composition combining berberine or its pharmaceutically acceptable salt form with pelargonium sidoides and propolis, using a diluent system of propylene glycol and glycerin, along with additional herbal extracts and a buffer system to enhance solubility and stability, while controlling pH and toxicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If berberine is formulated in solid oral dosage forms, then it is easier to manufacture and administer, but its solubility and bioavailability are reduced
Solution Approach 1:
The patent changes the physical state of berberine from solid to liquid formulation, and adjusts the pH parameter to 3-6 to enhance solubility and bioavailability while maintaining manufacturing feasibility
Solution Approach 2:
The patent creates a composite liquid formulation combining berberine with multiple herbal extracts (Pelargonium sidoides, propolis, and others) in a synergistic combination that improves both bioavailability and therapeutic effect
2Reliability
If multiple herbal extracts are combined in liquid formulation, then efficacy and bioavailability are improved, but solubility and stability become more difficult to maintain
Solution Approach 1:
The patent controls pH within the range of 3-6 to maintain stability of multiple herbal extracts in liquid form while preserving their therapeutic efficacy and solubility characteristics
Solution Approach 2:
The patent uses excipients as intermediary substances to facilitate the compatibility and stability of multiple herbal extracts in the liquid formulation, preventing precipitation and degradation
3Reliability
If berberine is formulated with higher concentration for better efficacy, then therapeutic effect is improved, but solubility and stability are compromised
Solution Approach 1:
The patent optimizes the concentration of berberine within specific ranges (0.1-10 mg/mL) and adjusts pH to 3-6 to achieve the maximum therapeutic effect while maintaining solubility and long-term stability of the formulation
