Acamprol (acamprosate calcium) is a clinically validated pharmacotherapy specifically formulated to support abstinence maintenance in alcohol-dependent patients following detoxification. As a synthetic compound with structural similarity to endogenous neurotransmitters, it modulates glutamatergic hyperactivity and GABAergic hypoactivity associated with chronic alcohol exposure. Its targeted mechanism addresses the neuroadaptations underlying craving and withdrawal, offering a physiological foundation for sustained recovery. Acamprol represents an essential component of comprehensive treatment programs when combined with psychosocial interventions.
Features
- Contains 333 mg acamprosate calcium per delayed-release tablet
- Synthetic compound with structural analogy to gamma-aminobutyric acid (GABA) and taurine
- Delayed-release formulation for consistent systemic delivery
- Renal excretion pathway with minimal hepatic metabolism
- Three-times-daily dosing regimen aligned with circadian neurotransmitter fluctuations
- Stable pharmacokinetic profile with negligible protein binding
- Manufactured under cGMP standards with batch-to-batch consistency
Benefits
- Reduces physiological craving intensity by normalizing glutamatergic neurotransmission
- Supports long-term abstinence through modulation of reward pathway hyperactivity
- Minimizes withdrawal-related distress by restoring inhibitory-excitatory balance
- Complements psychosocial interventions by addressing biological drivers of relapse
- Demonstrates efficacy across diverse patient demographics and drinking histories
- Provides predictable pharmacokinetics without significant drug accumulation
Common use
Acamprol is indicated for maintenance of abstinence in alcohol-dependent patients who have achieved initial detoxification. Clinical application typically begins immediately following the acute withdrawal period, with optimal efficacy observed when integrated within a comprehensive treatment program including counseling and behavioral support. The therapeutic effect manifests primarily through reduction of craving intensity rather than aversive effects or alcohol metabolism alteration. Treatment duration generally extends for 6-12 months, though continuation may be warranted based on individual patient assessment and relapse risk stratification.
Dosage and direction
The recommended dosage for most adults is two 333 mg tablets taken three times daily (total 1998 mg/day). Patients with moderate renal impairment (creatinine clearance 30-50 mL/min) should receive one tablet three times daily. Administration should occur with meals to enhance gastrointestinal tolerance while maintaining therapeutic efficacy. Tablets must be swallowed whole without crushing or chewing to preserve the delayed-release characteristics. Treatment initiation should occur as soon as possible after abstinence achievement, with consistent timing maintained to stabilize plasma concentrations.
Precautions
Renal function assessment is mandatory before initiation and periodically during treatment. Use caution in elderly patients and those with moderate renal impairment (dose adjustment required). Monitor for emergence of depression or suicidal ideation, particularly during early treatment phases. Does not eliminate or reduce withdrawal symptoms; ensure complete detoxification before initiation. Patients should be advised that Acamprol does not produce aversive effects when combined with alcohol but will not mitigate intoxication. Continue psychosocial support throughout treatment duration.
Contraindications
Severe renal impairment (creatinine clearance <30 mL/min). Hypersensitivity to acamprosate calcium or any excipient components. Pregnancy unless potential benefit justifies potential risk to fetus (Category C). Concomitant use with drugs having significant nephrotoxic potential without rigorous monitoring. Patients with history of seizure disorders requiring careful risk-benefit assessment. Lactation due to excretion in breast milk and unknown effects on nursing infants.
Possible side effects
Most common adverse reactions (≥5%) include diarrhea (10-17%), nausea (3-7%), abdominal pain (3-6%), and pruritus (4-5%). Less frequently observed effects: flatulence, vomiting, anorexia, dry mouth, headache, dizziness, insomnia, paresthesia, and various dermatological reactions. Cardiovascular effects including palpitations and syncope occur rarely (<1%). Psychiatric disturbances including anxiety, depression, and suicidal ideation require immediate clinical attention. Laboratory abnormalities may include transient elevations in liver enzymes without clinical significance.
Drug interaction
No clinically significant pharmacokinetic interactions with diazepam, imipramine, or alcohol. Potential pharmacodynamic interactions with other CNS depressants requiring vigilance. Concurrent use with naltrexone may enhance treatment efficacy but requires monitoring for additive gastrointestinal effects. Limited data exist regarding interactions with antidepressants or antipsychotics; initiate with caution. Does not affect cytochrome P450 enzyme system but may interact with drugs affecting renal clearance pathways.
Missed dose
If a dose is missed, take as soon as remembered unless approaching next scheduled dose. Do not double doses to compensate for missed administration. Maintain regular dosing schedule without significant disruption. Patients should be educated on maintaining consistent timing to stabilize neurotransmitter modulation. Extended missed doses (>24 hours) may require medical consultation to assess restart strategy.
Overdose
Experience with acute overdose is limited. Maximum reported ingestion was 56 tablets (18.6 g) with resulting diarrhea and restlessness without life-threatening consequences. No specific antidote exists; employ supportive measures including gastric lavage if presented early. Monitor electrolyte balance and renal function with large overdoses. Hemodialysis may be considered due to renal excretion pathway but efficacy remains unestablished. Contact poison control center for latest management recommendations.
Storage
Store at controlled room temperature (20-25°C/68-77°F) with excursions permitted to 15-30°C (59-86°F). Protect from moisture and light. Maintain in original container with tight closure. Keep out of reach of children and pets. Do not use beyond expiration date printed on packaging. Avoid storage in bathrooms or other high-humidity environments.
Disclaimer
This information does not replace professional medical advice. Healthcare providers should exercise clinical judgment regarding individual patient suitability. Full prescribing information should be consulted before initiation. Treatment should be administered under appropriate medical supervision with regular monitoring. Efficacy requires combination with comprehensive addiction treatment program.
Reviews
Clinical trials demonstrate consistent efficacy across multiple randomized controlled studies. Meta-analyses confirm significant improvement in cumulative abstinence duration (weighted mean difference 10.83 days, 95% CI 6.27-15.38) and reduced relapse risk (RR 0.86, 95% CI 0.80-0.93) versus placebo. Real-world evidence supports maintained effectiveness in heterogeneous clinical populations. Patient-reported outcomes indicate improved quality of life measures and treatment satisfaction scores. Long-term follow-up studies suggest sustained benefits post-discontinuation when integrated with comprehensive care.
