Solution Overview

Problem

Current treatments for intermittent claudication due to peripheral arterial disease primarily focus on pharmacological interventions, which may have limitations in improving both objective symptomatic and subjective quality of life, and do not adequately address the need for long-term patient compliance and safety, especially when combined with physical exercise recommendations that are not systematically integrated into the treatment protocol.

Innovation Solution

Administering an effective dose of propionyl L-carnitine concurrently with a prescribed physical training program, tailored to the patient's severity and condition, to enhance exercise tolerance and quality of life in patients with intermittent claudication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pharmacological interventions are used to treat intermittent claudication, then symptomatic improvement is achieved, but patient compliance and long-term safety are compromised

Engineering Contradiction:
Improvesymptomatic improvementVSAvoidpatient compliance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent combines propionyl L-carnitine administration with a structured physical training program into a single integrated treatment protocol. This merging of pharmacological and physical therapy approaches creates a comprehensive treatment that addresses both metabolic dysfunction and exercise capacity, improving overall compliance while maintaining symptomatic relief.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces specific dosage parameters for propionyl L-carnitine (2-4 grams daily) and structured exercise parameters (frequency, intensity, duration, type) to optimize treatment effectiveness. These parameter changes transform the treatment from a purely pharmacological approach to a standardized protocol that improves compliance through clear, measurable guidelines.

Inventive Principle:
Principle #35Parameter changes

2Duration of action of moving object

If pharmacological treatments are administered alone, then short-term symptomatic relief is achieved, but long-term quality of life improvement is limited

Engineering Contradiction:
Improveshort-term symptomatic reliefVSAvoidlong-term quality of life improvement
Core Design Contradiction:
Duration of action of moving objectVSReliability

Solution Approach 1:

The patent employs propionyl L-carnitine as a preliminary metabolic intervention that prepares the muscle tissue for subsequent physical training. This preliminary action addresses the underlying metabolic dysfunction before the physical training component, creating optimal conditions for long-term adaptation and sustained quality of life improvement.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent establishes a continuous treatment protocol where propionyl L-carnitine administration and physical training occur concurrently over an extended period. This continuity ensures sustained metabolic support during exercise adaptation, transforming short-term symptomatic relief into long-term quality of life improvement through persistent therapeutic action.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of operation

If physical exercise is recommended separately from pharmacological treatment, then general health advice is provided, but integrated therapeutic benefit is not achieved

Engineering Contradiction:
Improvegeneral health adviceVSAvoidintegrated therapeutic benefit
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent merges propionyl L-carnitine administration with a structured physical training program into a single integrated treatment protocol. This merging of pharmacological and physical therapy approaches creates a comprehensive treatment that addresses both metabolic dysfunction and exercise capacity, improving overall compliance while maintaining symptomatic relief.

AI summary

The present invention discloses a method for treating a subject suffering from intermittent claudication (IC) wherein said subject takes an effective dose of propionyl L-carnitine or a pharmaceutically acceptable salt thereof and also engaging in a concomitant physical training program. The method is particular effective for patients with intermittent claudication at class II of the Leriche-Fontaine's classification. The method provides a relief from peripheral arterial disease symptoms, as shown by claudication-limited exercise tolerance, while also improving quality of life.
