Acamprosate Medications
Acamprosate is a medication that assists in maintaining alcohol abstinence for individuals with alcohol dependence by restoring balance to brain chemicals affected by long-term alcohol use.
About Acamprosate
Acamprosate is a calcium-salt medication that helps adults maintain abstinence after completing alcohol-detoxification. Belonging to the class of glutamate-modulating agents, it works by dampening the brain’s hyper-active excitatory pathways that emerge during withdrawal. The drug is widely marketed under the brand name Campral and is also available as a generic tablet in Australia. While its primary indication is the prevention of relapse in alcohol-use disorder, clinicians sometimes consider it for related conditions such as cravings after binge-drinking episodes. Off-label use is limited, but some studies have explored its role in reducing anxiety-driven drinking; such applications remain unapproved by health regulators.
What is Acamprosate?
Acamprosate (calcium acetylhomotaurinate) is classified as a central nervous system depressant that mod glutamatergic neurotransmission. The Therapeutic Goods Administration (TGA) approved the medication for adult alcohol-dependence treatment in 2005, following earlier FDA approval in 2004 and subsequent endorsement by the European Medicines Agency. Its core molecular action involves antagonism of the N-methyl-D-aspartate (NMDA) receptor and indirect enhancement of γ-aminobutyric acidGABA) activity, thereby restoring the excitatory-inhibitory balance disrupted by chronic alcohol exposure. Acamprosate is sold as Campral® and as generic tablets, all of which can be ordered from our online pharmacy.
How Acamprosate Works
Mechanism of Action
Acamprosate blocks NMDA receptors, reducing glutamate-driven neuronal firing that contributes to craving and withdrawal symptoms. Simultaneously, it modestly potentiates GABA-A receptors, promoting inhibitory signalling. This dual effect stabilizes the brain’s neurochemical environment during early sobriety.
Therapeutic Effects
By temperatory neurotransmission, acamprosate lessens the intensity of alcohol cravings and reduces the risk of relapse. Patients often report fewer urges to drink after the first few weeks of consistent therapy.
Onset and Duration
Clinical trials indicate that measurable reductions in craving appear after approximately two weeks of daily dosing, with maximal benefit observed at 12 weeks. The drug’s half-life is about 20-33 hours, allowing for a stable plasma concentration with a twice-daily regimen.
Approved Uses and Applications
Approved Indications
- Alcohol-dependence maintenance: For adults who have achieved abstinence following detox, acamprosate is prescribed to sustain that state. (TGA; FDA Adjunct to psychosocial support: The medication is most effective when combined with counseling or mutual-help programs.
Off-Label Uses
- Craving reduction in binge-drinking patterns: Small pilot studies suggest a modest benefit, but the indication is not approved by any regulatory agency.
Clinical Efficacy
In a double-blind, placebo-controlled trial published in The New England Journal of Medicine, 60 % of participants receiving acamprosate remained abstinent at six months versus 35 % on placebo (p < .01). Another meta-analysis in Lancet Psychiatry reported an average 15 % absolute increase in abstinence rates across multiple studies.

Administration Guidelines
Take tablets with water; food does not significantly affect absorption, but consistent timing (e.g., with meals) can improve adherence. Patients with chronic kidney disease should have renal function evaluated before starting therapy.
A qualified healthcare provider must determine the exact dose based on individual factors.
Safety Profile & Considerations
Common Side Effects
- Diarrhea (≈15 % of patients)
- Nausea≈10 %)
- Flatulence (≈8 %)
- Dizziness (≈5 %)
These effects are typically mild and often resolve within the first month of therapy.
Serious Adverse Events
Rarely, acamprosate has been associated with severe depression, suicidal ideation, or allergic reactions such as Stevens-Johnson syndrome. Immediate medical attention is required if mood changes or skin eruptions occur.
Contraindications
- Severe renal impairment (creatinine clearance < 30 mL/min)
- Known hypersensitivity to acamprosate or any excipients
Drug Interactions
Acamprosate is not extensively metabolized by cytochrome P450 enzymes, but caution is advised when co-administered with:
- CNS depressants (e.g., benzodiazepines) - additive sedation
- Other alcohol-dependence agents (e.g., naltrexone) - overlapping mechanisms may increase adverse effects
Special Populations
- Pregnancy & Breastfeeding: Limited data; the TGA advises use only if the potential benefit outweighs risk.
- Older Adults: Renal function declines with age; dose adjustment may be necessary.
- Hepatic Impairment: Generally safe as the drug is excreted unchanged by the kidneys, clinicians should monitor liver enzymes in patients with active disease.
Frequently Asked Questions
-
How does Acamprosate differ from Naltrexone? Acamprosate targets glutamate and GABA pathways to reduce cravings, whereas naltrexone blocks opioid receptors to diminish the rewarding effects of alcohol.
-
How long before Acamprosate produces noticeable effects for alcohol dependence? Most patients report a reduction in cravings after 2-3 weeks of daily use, with optimal benefit seen after 8-12 weeks.
-
What should I do if I experience persistent diarrhea while taking Acamprosate? Maintain hydration, and contact a healthcare professional if loose stools continue beyond two weeks or are accompanied by abdominal pain.
-
Can Acamprosate be taken with food? Yes. Food does not markedly affect absorption, but taking the tablet with a meal can help reduce gastrointestinal upset.
-
Is Acamprosate safe for people with mild kidney impairment? The medication is excreted unchanged by the kidneys; dose reduction is recommended for moderate impairment, and it is contraindicated in severe renal failure.
What are the risks of combining Acamprosate with other alcohol-treatment drugs? Concurrent use may increase the likelihood of side effects such as dizziness or sedation; clinicians usually choose one pharmacologic agent based on the patient’s profile.
-
How does Acamprosate affect mood? While it generally has a neutral effect on mood, rare cases of depression have been reported; any mood changes should prompt immediate medical evaluation.
