Clofilium phosphate (LY 150378) is an antiarrhythmic/antifibrillatory agent. Clofilium phosphate significantly prolongs the action potential duration and effective refractory period of canine cardiac Purkinje fibers, increases the ventricular fibrillation threshold, reduces the risk of reentrant arrhythmias, and enables spontaneous conversion of some ventricular fibrillation episodes to sinus rhythm. Clofilium phosphate is applicable to research related to ventricular fibrillation, arrhythmias, and ventricular tachyarrhythmias.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
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.
