Compressed 3-NOP Tablets for Sustained Rumen Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current formulations of 3-nitrooxypropanol for reducing methane production in ruminants exhibit rapid disintegration and instantaneous release, which is not suitable for long-term methane reduction, as methane production in ruminants increases slowly after feeding.
Innovation Solution
Compressed tablets comprising 3-nitrooxypropanol and gluten, which remain intact and slowly release the active ingredient into aqueous media over an extended period, providing a slow and sustained release of the active compound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If 3-nitrooxypropanol is supplemented as 10% on silicon dioxide, then the active ingredient is instantly released into the aqueous rumen fluid, but this instant release is not suitable for long term methane reduction as methanogenic archaea increase slowly after feeding
Solution Approach 1:
The patent changes the physical and chemical parameters of the tablet formulation by using compressed tablets with specific density (0.6-1.2 g/cm³), hardness (5-20 kp), and water stability (less than 10% weight loss after 24 hours). These parameter changes enable the tablet to maintain structural integrity and control the release rate of 3-nitrooxypropanol, transforming it from instant release to sustained release over 4-24 hours, matching the slow increase of methanogenic archaea after feeding.
2Duration of action of moving object
If a compressed tablet formulation is used to achieve slow release, then the release duration is extended to 2-24 hours, but the tablet must maintain integrity and resist disintegration in aqueous media
Solution Approach 1:
The patent employs composite tablet formulations combining 3-nitrooxypropanol (0.01-10 wt%) with excipients including starch (10-50 wt%), microcrystalline cellulose (10-50 wt%), and binders (5-20 wt%). This composite structure creates a matrix that controls drug release while maintaining tablet integrity in aqueous environments, achieving both extended release duration and structural stability through the synergistic properties of different materials.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compressed tablets effectively inhibit methanogenic archaea growth, leading to sustained methane reduction in ruminants by maintaining the active ingredient's integrity and controlled release over 2-24 hours, addressing the limitations of rapid disintegration and instantaneous release in existing products.
Implementation Method 1
only slowly release the active into aqueous media over an extended period of time, such as 2-24 hours
Implementation Method 2
show no disintegration over a long period of time and only slowly release the active into aqueous media
Implementation Method 3
3-Nitrooxypropanol and structural analogues thereof have been reported to inhibit the growth of methanogenic archaea and thus significantly reducing the methane production in ruminants
