Triamcinolone Injection for Localized Fat Atrophy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating small fat accumulations, such as liposuction and injectable lipodissolve agents, are either too aggressive or associated with severe side effects and lack safety and efficacy for non-surgical fat reduction.
Innovation Solution
The use of subcutaneous administration of low-dose Triamcinolone and other corticosteroids, combined with anesthetic solutions and vasoconstriction agents, in a physiological pH solution to reduce small fat deposits without systemic absorption, minimizing risks and side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If surgical liposuction is used to remove subcutaneous fat, then fat removal effectiveness is improved, but patient safety and risk profile worsen due to aggressive nature and known complications
Solution Approach 1:
The patent replaces the mechanical surgical system (liposuction) with a chemical/biological system (corticosteroid injection). Instead of mechanically suctioning fat, the invention uses triamcinolone acetonide injection to induce fat cell atrophy through biochemical mechanisms, thereby eliminating surgical risks while maintaining fat removal effectiveness
Solution Approach 2:
The patent introduces corticosteroid (triamcinolone acetonide) as an intermediary substance that mediates between the treatment goal (fat removal) and safety requirement. The drug acts as a mediator that selectively targets fat cells for atrophy without the direct mechanical trauma of liposuction, reducing complications while achieving cosmetic improvement
2Ease of operation
If injectable lipodissolve agents (phosphatidylcholine, sodium deoxycholate) are used for fat reduction, then non-surgical treatment is achieved, but safety worsens due to severe side effects including death in animals
Solution Approach 1:
The patent changes the chemical parameters of the injectable agent from lipodissolve agents (phosphatidylcholine, sodium deoxycholate) to a corticosteroid (triamcinolone acetonide). This parameter change in drug composition maintains the non-surgical injection approach while dramatically improving safety by eliminating the severe toxic effects associated with lipodissolve agents
Solution Approach 2:
The patent employs a well-established, extensively studied corticosteroid formulation that is already approved for medical use, replacing the experimental and unproven lipodissolve agents. This substitution uses a known-safe substance with a long track record of clinical use, eliminating the need to test unproven chemicals on patients
3Productivity
If high-dose corticosteroids are administered for fat reduction, then fat atrophy effectiveness is improved, but side effects worsen due to systemic absorption and known corticosteroid toxicity
Solution Approach 1:
The patent applies corticosteroid injection with specific attention to local administration parameters - using appropriate injection depth (subcutaneous), dosage (40-80mg per session), and frequency (monthly) to achieve local fat atrophy while minimizing systemic exposure. The treatment is localized to specific fat deposits rather than systemic administration
Solution Approach 2:
The patent uses controlled dosing of corticosteroid (40-80mg per injection session) that is sufficient to achieve fat atrophy in targeted areas but limited enough to avoid cumulative systemic toxicity. The treatment employs partial action (localized injections) rather than excessive systemic dosing, achieving therapeutic effect with minimal harm
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach provides a safe, effective, and minimally invasive method for reducing small fat deposits, offering cosmetic improvements with low risk of systemic side effects and avoiding the complications of surgical treatments.
Implementation Method 1
Injectable corticosteroids... which is suitable for producing medicaments to diminish small fat accumulations on the face and body by causing atrophy of the fat cells

AI summary
Methods relating to local injections of corticosteroids are provided. More specifically intralesional injections of corticosteroids and preferably Triamcinolone and its derivatives are suitable to produce medicaments to be injected in the subcutaneous fat at deep levels to provoke cosmetic lipoatrophy of small fat deposits on the face and body.
