Firocoxib (ML is a nonsteroidal anti-inflammatory drug that acts as a potent and selective cyclooxygenase-2 (COX-2) inhibitor over COX-1. By preferentially targeting COX-2, firocoxib inhibits the conversion of arachidonic acid into pro-inflammatory prostaglandins. Disruption of this cyclooxygenase enzymatic pathway reduces prostaglandin E2 production, suppressing downstream inflammatory signaling cascades and attenuating pyrexia and pain responses. [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).
