Solution Overview

Problem

There is a lack of reliable medicinal recommendations for treating sexual disorders, particularly in females, and existing antidepressants often exacerbate sexual side effects, necessitating a treatment that can effectively address hypoactive sexual desire, orgasmic, and arousal disorders in both short-term and long-term therapies.

Innovation Solution

Gepirone, a drug initially investigated for its antidepressant effects, is administered in effective amounts for the improvement of sexual drive and treatment of sexual dysfunction disorders, including hypoactive sexual desire and orgasmic disorders, as a short-term or long-term therapy, either alone or in combination with other pharmaceutical auxiliaries, providing a pharmaceutical composition for oral, parenteral, or topical administration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If antidepressant drugs with serotonin reuptake inhibiting effect are used to treat depression, then depressive symptoms are improved, but sexual dysfunction occurs as a side effect

Engineering Contradiction:
Improvedepression treatment efficacyVSAvoidsexual dysfunction side effect
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the harmful sexual dysfunction side effect from the antidepressant treatment by using gepirone, a selective 5-HT1A receptor partial agonist, which provides antidepressant effects without the sexual dysfunction associated with traditional serotonin reuptake inhibitors. This separates the therapeutic benefit from the adverse effect.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the pharmacological parameter from non-selective serotonin reuptake inhibition to selective 5-HT1A receptor partial agonism. Gepirone has high affinity for 5-HT1A receptors with minimal affinity for other serotonin receptors, fundamentally changing the mechanism of action to eliminate sexual dysfunction while maintaining antidepressant efficacy.

Inventive Principle:
Principle #35Parameter changes

2Duration of action of stationary object

If traditional antidepressants are used for long-term therapy, then depression is managed, but sexual dysfunction persists and may worsen

Engineering Contradiction:
Improvelong-term depression managementVSAvoidchronic sexual dysfunction
Core Design Contradiction:
Duration of action of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The patent converts the previously harmful long-term use of antidepressants into a beneficial treatment by using gepirone, which provides sustained antidepressant effects without the chronic sexual dysfunction. The selective 5-HT1A agonism mechanism transforms the long-term treatment profile from harmful to beneficial regarding sexual function.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Speed

If fast-acting pharmaceutical formulations are used for as-needed treatment of premature ejaculation, then immediate effect is achieved, but they are not suitable for long-term therapy of sexual disorders

Engineering Contradiction:
Improveimmediate therapeutic effectVSAvoidlong-term therapy suitability
Core Design Contradiction:
SpeedVSDuration of action of stationary object

Solution Approach 1:

The patent creates a universal treatment approach with gepirone that serves multiple functions: it can be used for long-term management of various sexual disorders including hypoactive sexual desire, arousal disorders, and orgasmic disorders in both men and women, as well as for premature ejaculation, eliminating the need for different formulations for different indications.

Inventive Principle:
Principle #6Universality (Multi-functionality)
