Butamben, also known as Butoform, is a local anesthetic. Blockade of voltage-gated channel expressed in the peripheral sensory neurons has been suggested as a mechanism of action. Butaben effects on another sensory neuronal channel family, transient receptor potential (TRP) have remained unclear. Butamben attenuated acute animal pain behaviors in a TRPA1- or TRPV4-dependent manner. Butamben inhibits the total barium current through expressed calcium channel types in PC12 cells, including Cav1.2/L-type channels.

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.
