Acamprosate

Acamprosate

January 6, 2020

Acamprosate is a medicine used in the treatment of alcoholism. Alcoholism is a condition in which a person has a physical need or a desire to drink alcohol even though it has a negative impact on their life. An alcoholic person does not know how or when to stop drinking. They spend a lot of time thinking about alcohol. Once they started drinking, they cannot control how much alcohol they consume, even if it is causing serious problems at work, home and financially.

Acamprosate is one of the few drugs approved by the U.S Food and Drug Administration for the treatment of alcoholism since 2002 but it has been widely used in Europe for many years. This medication was the third medication to receive U.S FDA approval for post-withdrawal maintenance of alcohol abstinence. Its mechanism of action has not clearly been established but it is believed to help normalize and modulate alcohol-related changes in the brain. It reduces cravings and desires to drink alcohol to those alcoholics who were able to manage to stop drinking.

The balance of neurotransmitter in your brain changes when you are a heavy drinker.  The excitatory neurotransmitter glutamate decreases creating a sedative effect. When you quit drinking, the amount of glutamate increased which results in hyperactivity and excitability. This can cause a person to crave for alcohol and to quell uncomfortable symptoms.

It is believed to restore the chemical balance in the brain that is disrupted by chronic alcohol abuse. It corrects the underlying neurochemical changes in the brain caused by chronic drinking so the brain can function normally. This way, an alcoholic can abstain from drinking alcohol.

Acamprosate reduces emotional discomfort and physical distress alcoholics usually experience when they quit drinking. It reduces many of the post0acute withdrawal symptoms that alcoholics experiences during the early stage of alcohol abstinence such as anxiety, sweating and sleep disturbances. It works best if it is used along with social support and counseling to help people who have stopped drinking a large amount of alcohol so they can avoid drinking alcohol again. However, Acamprosate does not prevent the withdrawal symptoms that alcoholics may experience when they stop drinking alcohol.

How to Use Acamprosate
