Campral

What is Campral?

Campral (generic name : acamprosate) is a prescription medication approved in the United Kingdom for the maintenance of abstinence from alcohol in adults with alcohol-dependence syndrome. It is supplied as a 333 mg oral pill. The drug is regulated by the Medicines and Healthcare products Regulatory Agency (MHRA) and is classed as a prescription-only medicine (POM).

How Campral Works in the Body

Acamprosate acts primarily on the brain’s neurotransmitter systems that become dysregulated after chronic alcohol use. Its main pharmacological actions are:

• Modulation of glutamate receptors - Acamprosate reduces activity at the NMDA subtype of glutamate receptors, helping to restore the excitatory-inhibitory balance that is disturbed during alcohol withdrawal.
• Enhancement of GABA-ergic tone - It modestly potentiates the inhibitory neurotransmitter GABA, contributing to a calming effect on neuronal firing.

By dampening the hyper-excitatory state that drives cravings and by supporting inhibitory pathways, acamprosate helps reduce the urge to resume drinking. The drug reaches peak plasma concentrations within 3-5 hours after oral intake and is largely excreted unchanged by the kidneys, giving it a half-life of about 30 hours.

Conditions Treated by Campral

Alcohol-dependence (maintenance of abstinence) Campral is indicated in the UK for adults who have achieved initial abstinence from alcohol and require pharmacological support to maintain that abstinence. Clinical trials have demonstrated that, when used as part of a comprehensive treatment program (counselling, behavioral therapy, and support groups), acamprosate reduces the risk of relapse compared with placebo.

Note: Campral is not approved for smoking cessation or for other substance-use disorders.

Patient Suitability and Contraindications

Who should consider Campral?

• Adults (≥ 18 years) with a diagnosed alcohol-dependence disorder who have been abstinent for at least 3 days.
• Individuals with stable renal function (creatinine clearance ≥ 30 mL/min).

Absolute Contraindications

• Known hypersensitivity to acamprosate or any of the pill’s inactive ingredients.
• Severe renal impairment (creatinine clearance < 30 mL/min).

Relative Contraindications / Cautions

• Moderate renal impairment (creatinine clearance 30-50 mL/min): dose may need adjustment.
• Pregnancy or lactation: safety data are limited; use only if the potential benefit outweighs the risk.
• Elderly patients: may require closer monitoring of renal function.

Special Populations

• Pregnancy: Acamprosate is classified as Pregnancy Category B2 in the UK; discuss risks with a healthcare professional.
• Lactation: Small amounts are excreted in breast milk; breastfeeding decisions should be made with a clinician’s guidance.

Safety Profile: Side Effects and Interactions

Common Side Effects

• Diarrhoea - frequently reported; usually mild and transient.
• Nausea - may occur, often improving after the first few days of therapy.
• Flatulence - occasional, typically mild.

Serious Adverse Events

• Severe renal dysfunction - rare but possible, especially in patients with pre-existing kidney disease; symptoms may include decreased urine output, swelling, or fatigue.
• Allergic reactions - rash, pruritus, or angioedema require immediate medical attention.

Drug Interactions

• Renal-clearing drugs (e.g., certain diuretics, aminoglycoside antibiotics) may increase the risk of acamprosate accumulation; monitor renal function.
• CNS depressants (e.g., benzodiazepines, opioids) have additive sedative effects; dose adjustments may be necessary.
• No known significant interactions with CYP450 enzymes, as acamprosate is excreted unchanged.

If you are taking other medications, supplements, or herbal products, inform your prescriber before starting Campral.

Food and Lifestyle Interactions

• Food: Acamprosate can be taken with or without food; taking it with a meal may lessen gastrointestinal upset.
• Alcohol: Even small amounts of alcohol can counteract the medication’s benefit and increase side-effect risk; abstinence is advised.
• Driving: The drug does not impair driving ability in most patients, but those who experience dizziness or severe nausea should avoid operating machinery until symptoms resolve.

How to Take Campral

• Standard dosing: One 333 mg pill taken three times daily (total daily dose = 999 mg).
• Timing: Space doses evenly - for example, morning, afternoon, and evening - and take them at the same times each day.
• Administration: Swallow the pill whole with a glass of water; do not crush or chew.
• Missed dose: If a dose is forgotten and the next scheduled dose is more than 4 hours away, take the missed dose. Do not double-dose to make up for a forgotten tablet.
• Overdose: Symptoms may include severe nausea, vomiting, dizziness, or confusion. Seek emergency medical care; there is no specific antidote, and treatment is supportive.
• Discontinuation: No tapering is required. If therapy is stopped, patients should continue to engage in counselling and support programs to prevent relapse.

Monitoring and Follow-Up

• Renal function: Baseline serum creatinine and estimated glomerular filtration rate (eGFR) should be measured before starting Campral, then periodically (e.g., every 6-12 months) or sooner if renal disease is suspected.
• Clinical response: Evaluate drinking behaviour at least monthly during the first 3 months, then at regular intervals (e.g., every 3-6 months).
• Adverse effects: Promptly report persistent diarrhoea, severe nausea, or signs of allergic reaction to a healthcare provider.

Storage and Handling

• Keep Campral tablets in their original blister pack until use.
• Store at room temperature (15 °C - 30 °C) away from excess moisture and direct sunlight.
• Do not use the medication past the expiry date printed on the package.
• Keep out of reach of children; use a child-proof container if repackaging is necessary.

Medication-Specific Glossary

Acamprosate

The active ingredient in Campral; a calcium salt that modulates glutamatergic and GABAergic neurotransmission to reduce alcohol cravings.

Glutamate

The primary excitatory neurotransmitter in the central nervous system; excessive activity is linked to withdrawal symptoms in alcohol dependence.

GABA (Gamma-aminobutyric acid)

The main inhibitory neurotransmitter in the brain; enhanced GABA activity contributes to a calming effect.

Creatinine clearance

A measure of kidney filtration efficiency used to assess whether a drug that is eliminated by the kidneys is safe to use.
