Dronabinol Solid Dosage Packaging for Room-Temperature Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dronabinol compositions, particularly in oral solid dosage forms, lack stability at room temperature, necessitating refrigerated storage, which is burdensome for vendors and patients.
Innovation Solution
Packaging dronabinol oral solid dosage forms with a separate oxygen scavenger in a container to prevent oxidative degradation and increase shelf life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dronabinol is stored at room temperature, then ease of operation is improved, but stability deteriorates
Solution Approach 1:
An oxygen scavenger is introduced as an intermediary substance in the packaging system to remove oxygen from the container headspace. This mediator prevents direct contact between oxygen and dronabinol, thereby maintaining stability at room temperature without requiring refrigeration.
Solution Approach 2:
The packaging system creates an inert atmosphere by using an oxygen scavenger to eliminate oxygen from the container environment. This transforms the storage environment from an oxygen-containing atmosphere that promotes degradation to an oxygen-free inert atmosphere that preserves dronabinol stability at room temperature.
2Stability of the object's composition
If refrigerated storage is used, then stability is improved, but device complexity increases
Solution Approach 1:
The oxygen scavenger serves as a chemical intermediary that actively removes oxygen from the packaging headspace. This mediator enables room temperature storage by preventing oxidative degradation, thereby eliminating the need for complex refrigerated storage infrastructure.
Solution Approach 2:
The packaging system changes the chemical parameter of the storage environment by using an oxygen scavenger to reduce oxygen concentration to near-zero levels. This parameter change (from ambient oxygen levels to oxygen-free conditions) allows stability at room temperature, removing the need for temperature-controlled storage.
3Stability of the object's composition
If oxygen is present in packaging, then oxidative degradation occurs, but removing oxygen increases packaging complexity
Solution Approach 1:
An oxygen scavenger packet or canister is placed inside the container as an intermediary oxygen-removing agent. This simple additive component absorbs residual oxygen in the headspace without requiring complex vacuum sealing or inert gas filling systems, thus maintaining stability while minimizing packaging complexity.
Solution Approach 2:
The oxygen scavenger is implemented as a disposable, single-use component (packet or canister) that is inexpensive and simple in design. This short-living oxygen-absorbing element provides effective oxygen removal during the product shelf life without requiring complex reusable oxygen-exclusion systems.
