Campral EC tablets contain the active ingredient acamprosate, which is a medicine used in the treatment of alcohol dependence. In alcoholics who have managed to stop drinking it is used to reduce cravings and desire to drink alcohol.
Acamprosate has a structure similar to chemical messengers (neurotransmitters) that are found in the brain, such as gamma aminobutyric acid (GABA). These neurotransmitters act by sending inhibitory messages to the brain, and acamprosate is thought to act by enhancing their inhibitory effects. It is also thought to oppose the action of certain amino-acids that send excitatory messages to the brain. These actions in the brain help to reduce your cravings for alcohol.
Acamprosate is only effective after you have completely stopped drinking alcohol, and will be used in conjunction with a counselling programme to help you maintain abstinence from alcohol. It is important to realise that you still will need to use your own determination and willpower to avoid starting to drink again, and counselling will help with this.
