Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing treatments for hair loss, such as topical minoxidil, often result in rapid absorption and short duration of action, leading to suboptimal therapeutic effects and potential adverse effects due to peak serum concentrations.

Innovation Solution

A modified release formulation of minoxidil or its pharmaceutically acceptable salt, designed for oral administration, which releases 50% to 98% of the daily dose within 12 hours, with a Tmax of 30 to 360 minutes and Cmax of 0.25 ng/ml to 20 ng/ml, providing sustained pharmacokinetic profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If topical minoxidil is used for hair loss treatment, then it can be applied locally to the scalp, but rapid absorption occurs leading to short duration of action and suboptimal therapeutic effects

Engineering Contradiction:

Improveduration of actionVSAvoidtherapeutic effect

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent segments the minoxidil dosage into multiple controlled-release units (microspheres, pellets, or layered tablet structures) that release the drug at different rates. This segmentation allows the formulation to provide sustained release of minoxidil over an extended period, resolving the contradiction between rapid absorption and short duration of action while maintaining reliable therapeutic effects.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes the release rate parameter of minoxidil by using modified-release formulations with different release characteristics (immediate-release, sustained-release, delayed-release). By controlling the release rate parameter through formulation design, the patent achieves both extended duration of action and maintained therapeutic efficacy, resolving the contradiction between rapid absorption and suboptimal therapeutic effects.

Principle #35Parameter changes

2Object-affected harmful factors

If topical minoxidil is applied to the scalp, then local treatment is achieved, but peak serum concentrations cause potential adverse effects

Engineering Contradiction:

Improveadverse effectsVSAvoidserum concentration

Core Design Contradiction:

Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent uses dynamic release profiles where the minoxidil formulation adjusts its release rate over time. The modified-release formulations provide an initial release phase followed by a sustained release phase, creating a dynamic serum concentration profile that avoids sharp peaks while maintaining therapeutic levels. This dynamic approach resolves the contradiction between achieving effective serum concentrations and avoiding adverse effects from peak concentrations.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent employs periodic or pulsed release patterns where minoxidil is released in controlled intervals rather than all at once. This periodic action creates multiple smaller concentration waves instead of one large peak, maintaining therapeutic efficacy while reducing the risk of adverse effects associated with high peak serum concentrations.

Inventive Principle:

Principle #19Periodic action

3Speed

If immediate-release minoxidil is administered, then rapid onset of action is achieved, but the duration of therapeutic effect is short

Engineering Contradiction:

Improveonset of actionVSAvoidduration of therapeutic effect

Core Design Contradiction:

SpeedVSDuration of action of moving object

Solution Approach 1:

The patent segments the minoxidil dose into multiple release phases within a single formulation. Some segments provide immediate release for rapid onset, while other segments provide sustained release for extended duration. This segmentation allows the formulation to achieve both rapid onset of action and prolonged therapeutic effect, resolving the contradiction between speed and duration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses composite formulations combining different release mechanisms (e.g., immediate-release matrix combined with sustained-release microspheres, or layered tablets with different release rates). This composite approach integrates the benefits of rapid onset from immediate-release components with the extended duration from sustained-release components, resolving the contradiction between speed and duration of therapeutic effect.
