Anwendungen

It is a potassium channel blocker in nerve terminals. It inhibits potassium channel efflux, increasing the duration of the action potential, which results in an increase in the duration of calcium channel opening and enhanced acetylcholine (ACh) release. Increased ACh availability at the motor end plate allows muscles to contract.

Bemerkungen

Store under cool dry place. Ensure good ventilation. Incompatible with oxidizing agents.
