Activatable Drug Dispensing System

A system for controlling an electrolytic reaction in a reaction medium, the system comprising

• a primary energy storage,
• an intermediate storage and
• a control unit,
• the control unit being adapted for
• transferring electric energy from the primary energy storage into the intermediate storage,
• monitoring the state of charge of the intermediate storage,
• establishing an electric connection between the reaction medium and the intermediate storage when the state of charge of the intermediate storage is larger than or equal to a first threshold value, and
• interrupting an electric connection between the reaction medium and the intermediate storage when the state of charge of the intermediate storage is smaller than or equal to a second threshold value, so as to interrupt the current flow from the system to the reaction medium.

A method for transferring electric charges from a primary energy storage into a transdermal application system, which comprises the following steps:

• (a) transferring electric charges from a primary energy storage into an intermediate storage at a transfer rate not exceeding a predetermined value,
• (b) comparing the state of charge of the intermediate storage with a first predetermined state of charge,
• (c) establishing an electric connection between the intermediate storage and the transdermal application system when the state of charge corresponds to or exceeds the first predetermined state of charge,
• (d) comparing the state of charge of the intermediate storage to a second predetermined state of charge,
• (e) disconnecting the electric connection between the intermediate storage and the transdermal application system when the state of charge corresponds to or falls below the second predetermined state of charge.
