Biological descriptionSodium channel blocker. Class IC antiarrhythmic agent. Inhibits fast Na+ current in cardiac muscle in a use- and concentration-dependent manner. Also inhibits cardiac ryanodine receptors. Orally-active.
Storage instructionsStore at +4°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in ethanol to 100 mM and in DMSO to 50 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
