Abstract:
Leukotrienes are important mediators of inflammatory and allergic conditions in people and are suspected to play an important role in tumorigenesis and tumor growth of several different tumor types. Based on this, researchers are making great progress in identifying novel pharmacologic targets for several human diseases. Leukotriene inhibition has resulted in therapeutic benefit in clinical trials involving people with osteoarthritis, allergic asthma, and atopic dermatitis. Despite this progress and the possibility that leukotriene inhibition may also play an important therapeutic role in veterinary patients, parallel advances have not yet been made in veterinary medicine. This article summarizes leukotriene function and synthesis. It also reviews the published literature regarding potential therapeutic applications of leukotriene inhibition in both human and veterinary medicine, focusing primarily on osteoarthritis, NSAID induced gastrointestinal mucosal damage, allergic asthma, atopic dermatitis, and cancer.
Insights
Leukotriene inhibition shows therapeutic benefits for inflammatory conditions in humans, with potential applications in veterinary medicine for diseases like osteoarthritis and cancer.
Area of Science:
- Biomedical Science
- Pharmacology
- Inflammation Research
Background:
- Leukotrienes are key mediators in human inflammatory and allergic conditions.
- Leukotriene pathways are implicated in tumorigenesis and tumor progression.
- Leukotriene inhibition has demonstrated efficacy in human clinical trials for osteoarthritis, asthma, and dermatitis.
Purpose of the Study:
- To summarize leukotriene function and synthesis.
- To review the therapeutic potential of leukotriene inhibition in human and veterinary medicine.
- To focus on applications in osteoarthritis, NSAID-induced gastrointestinal damage, asthma, dermatitis, and cancer.
Main Methods:
- Literature review of leukotriene function, synthesis, and inhibition.
- Analysis of published data on therapeutic applications in human medicine.
- Exploration of potential veterinary applications based on human data.
Main Results:
- Leukotriene inhibition is effective for osteoarthritis, allergic asthma, and atopic dermatitis in humans.
- Leukotrienes are implicated in cancer development and growth.
- Significant progress in human therapeutic applications contrasts with limited veterinary research.
Conclusions:
- Leukotriene inhibition holds promise for treating various inflammatory diseases and cancers in humans.
- Further research is needed to translate these findings into veterinary therapeutic strategies.
- Leukotriene inhibition represents a potential, yet underexplored, treatment avenue in veterinary medicine.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
