What is Naltrexone?

Naltrexone is an opioid antagonist medication designed to block the effects of opioids in the body. It works at the receptor level to change how the brain responds to these substances. Various forms, such as prolonged-release tablets and film-coated tablets, exist to suit different therapeutic requirements and metabolic needs for individuals following a specific care plan.

By blocking the receptors in the brain that respond to opioids, it serves a distinct function in long-term treatment strategies. Additionally, specific combinations containing this ingredient are utilised for Weight Management when combined with structured diet and exercise plans.

How does Naltrexone work?

Naltrexone functions by binding to opioid receptors in the brain, effectively occupying these sites so that other opioid substances cannot trigger the same chemical response. This mechanism reduces the urge to consume alcohol or opioids, as the typical reward response associated with these substances is blunted. For those using it for weight control, the medication influences appetite regulation pathways in the central nervous system to reduce food cravings.
