Ordering Information

Biological Activity

Nicardipine HCl is a dihydropyridine calcium channel blocker that targets L-type voltage-gated calcium channels. By inhibiting calcium ion influx across vascular smooth muscle cell membranes, it prevents smooth muscle contraction and promotes vasodilation. This blockade inhibits intracellular calcium-dependent signaling, resulting in reduced vascular resistance, systemic arterial pressure lowering, and improved vascular blood flow in cardiovascular and cerebrovascular models.

FAQ
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).
