Fractionated Drug Dosing at Short Intervals for Better Therapeutic Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dose optimization methods for therapeutic agents fail to account for the potential benefits of fractionating doses, leading to suboptimal therapeutic effects and side effects.
Innovation Solution
A method of fractionating doses into two or more dose-fractions delivered at short time intervals, typically ranging from 30 seconds to 30 minutes, to enhance therapeutic effects and minimize side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single conventional dose is administered, then the total dose is delivered efficiently, but the therapeutic effect is suboptimal and side effects increase
Solution Approach 1:
The patent divides a single conventional dose into multiple smaller dose-fractions administered at short time intervals (30 seconds to 30 minutes apart). This segmentation of the total dose into fractionated doses delivers the same cumulative amount of drug but in divided portions, which unexpectedly enhances therapeutic effect while reducing side effects compared to single-dose administration.
2Reliability
If doses are fractionated into multiple administrations, then therapeutic effect is enhanced, but the dosing schedule becomes more complex
Solution Approach 1:
The patent implements a periodic dosing regimen where fractionated doses are administered at regular short intervals (30 seconds to 30 minutes) followed by longer intervals (hours) between fractionated-dose administrations. This periodic structure provides a systematic and repeatable dosing schedule that enhances therapeutic effect while maintaining operational feasibility through its rhythmic nature.
3Ease of operation
If the same total dose is delivered in a single administration, then the dosing process is simple, but side effects increase and therapeutic efficacy is reduced
Solution Approach 1:
By segmenting the total dose into multiple fractionated administrations delivered at short intervals, the patent reduces side effects while maintaining dosing simplicity. The segmented approach allows the same cumulative dose to be delivered in a manner that minimizes adverse reactions, making the process both simple and safe.
Solution Approach 2:
The patent changes the temporal parameter of dose delivery by introducing short time intervals (30 seconds to 30 minutes) between fractionated doses. This parameter change in the dosing schedule transforms the delivery pattern from single-shot to fractionated, thereby reducing side effects while keeping the total dose constant.

AI summary
The efficacy of a dosing regimen can be altered, and preferably improved, by fractionating the doses. Here fractionating the doses can be regarded as taking a single conventional dose and splitting that dose into two or more dose-fractions delivered at relatively short time intervals, where the dose-fractions add up to the same total dose as the conventional dose. In cases where dose fractionation increases the therapeutic effect, this can result in a greater therapeutic effect from a smaller total dose when the doses are fractionated. This effect has been demonstrated in an ophthalmic application, but is expected to be more generally applicable.
