Ibuprofen Dosing Regimen for Sustained Pain Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ibuprofen dosing regimens for pain management often require multiple administrations throughout the day, which can be inconvenient and may not provide sustained therapeutic effects over extended periods.
Innovation Solution
A novel dosing regimen that administers an initial immediate release dose of ibuprofen followed by a delayed sustained release dose in a single dosing step, achieving a prolonged plasma concentration of 5-10 mcg/mL for at least 8 hours, thereby providing continuous pain relief without the need for further dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple immediate release doses of ibuprofen are administered throughout the day, then pain relief efficacy is maintained, but patient convenience deteriorates and dosing complexity increases
Solution Approach 1:
The patent combines multiple ibuprofen doses into a single administered unit containing both immediate release and sustained release formulations. This merging allows the patient to receive what would traditionally require multiple separate doses through one single dose, thereby maintaining pain relief efficacy while significantly improving dosing convenience and reducing dosing frequency from multiple times daily to once daily.
Solution Approach 2:
The single administered unit is prepared in advance with both immediate release and sustained release ibuprofen formulations integrated together. The immediate release portion provides rapid initial analgesia while the sustained release portion is pre-configured to gradually release ibuprofen over an extended period, ensuring continuous pain relief without requiring the patient to remember or administer additional doses throughout the day.
2Speed
If immediate release ibuprofen is administered, then rapid onset of action is achieved, but duration of therapeutic effect is insufficient
Solution Approach 1:
The patent employs a composite dosing formulation that integrates two distinct ibuprofen release mechanisms: immediate release formulation for rapid onset of action and sustained release formulation for extended duration of therapeutic effect. This composite approach allows both rapid analgesia initiation and prolonged pain relief coverage within a single administered unit, eliminating the need to choose between fast-acting but short-duration or slow-acting but long-duration options.
Solution Approach 2:
The single administered unit delivers ibuprofen in a periodic fashion: an initial burst of immediate release provides rapid onset, followed by periodic sustained release over an extended period. This periodic action pattern ensures that therapeutic levels are quickly achieved and then maintained consistently throughout the day, providing both rapid onset and prolonged duration of effect.
3Productivity
If sustained release formulations are used, then dosing frequency is reduced, but onset of action is delayed
Solution Approach 1:
The patent segments the total daily ibuprofen dose into two functional components within a single administered unit: an immediate release portion that provides rapid initial analgesia and a sustained release portion that maintains therapeutic levels over time. This segmentation allows the formulation to deliver both fast onset (from the immediate release component) and reduced dosing frequency (from the sustained release component) simultaneously, resolving the contradiction between these two desirable properties.

AI summary
A method of administering non-steroidal-anti-inflammatory drugs, in particular propionic acid derivatives such as ibuprofen, is provided. The inventive dosage forms provide an initial release of the NSAID and a second sustained release of NSAID, preferably in a single dosing step.
