About Naltima 50
Naltrexone, an opioid receptor antagonist, is an ingredient in Naltima 50 mg.
It belongs to the therapeutic category of substance dependence treatment and acts centrally within the brain.
Without activating opioid receptors, naltrexone competitively binds to them.
Blocking these receptors prevents opioids from producing euphoria and reduces the rewarding effects associated with alcohol consumption.
This pharmacological action helps reduce:
- Cravings for alcohol
- Urges to use opioids
- Risk of relapse
- Compulsive substance-seeking behaviour
The effects of naltrexone are not similar to those of opioids.
Doctors typically initiate treatment only after detoxification to prevent precipitated withdrawal.
For optimal outcomes, combine Naltrexone therapy with counselling and behavioural support, in line with NICE and UK clinical guidance.
Benefits
Naltima 50 mg supports sustained recovery by reducing the reinforcing neurochemical response linked to substance use.
By blocking opioid receptors, Naltrexone lowers relapse risk and helps maintain abstinence.
Although it is not a centrally acting analgesic, it prevents opioid medicines from producing pain-relieving effects.
When used as directed, Naltrexone boosts treatment success and enhances long-term recovery.

What Conditions Naltima 50 Treats
Naltima 50 mg treats substance use disorders, which affect the brain’s reward pathway and behavioural control mechanisms.
Naltrexone acts specifically on opioid receptors within the central nervous system.

- Loss of control over use
- Withdrawal symptoms
- Compulsive behaviour
To promote a long-lasting recovery, stick with your treatment for the full time your doctor has prescribed.
