Epinastine HCl (WAL-801CL) is a potent histamine H1 receptor antagonist and mast cell stabilizer. It inhibits the release of histamine and inflammatory mediators from mast cells and basophils, suppressing histamine H1 receptor-mediated signaling pathways. Consequently, epinastine attenuates vascular hyperpermeability, reduces ocular inflammation, and suppresses allergic responses in preclinical models. [1]

Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
Pre-aliquoted for Longevity: Solid-state aliquots offer significantly longer shelf life compared to stock solutions, ensuring maximum stability for every use.
