(±)-Tazifylline is primarily used in research settings to study its pharmacological properties, particularly its potential as an antihistamine and anti-inflammatory agent. It has been investigated for its ability to modulate allergic responses by inhibiting histamine receptors, which could make it useful in treating conditions like allergic rhinitis or asthma. Additionally, its anti-inflammatory effects are explored for potential applications in managing inflammatory diseases. However, its use remains largely experimental, and further studies are needed to determine its efficacy and safety in clinical applications.
