Naldix (Naltrexone Hydrochloride)

Naltrexone hydrochloride works by competitively binding to μ‑opioid receptors and also antagonising κ and δ receptors. This blocks both endogenous opioids and exogenous opioid agonists from activating the receptors, thereby lowering the reinforcing and rewarding effects of alcohol and opioid substances.

The exact dose of Naldix is determined by the prescribing clinician based on the individual’s medical condition, response, and tolerance. Typical regimens involve oral administration, but the prescriber sets the strength, frequency and duration of therapy according to current clinical guidelines.

Safety data for naltrexone hydrochloride in pregnancy and lactation are limited. The product is classified as having an unknown pregnancy category, and it should only be used when the potential benefit justifies any potential risk to the fetus or infant. Consultation with a healthcare professional is essential.

For alcohol dependence, alternatives such as acamprosate act on glutamate pathways, whereas Naldix targets opioid receptors, offering a different mechanism that may be preferred in patients with co‑occurring opioid use. In opioid dependence, methadone and buprenorphine are opioid agonists/partial agonists, while Naldix is a pure antagonist, making it useful for relapse prevention after detoxification.

Naldix tablets should be stored at ambient temperature, below 25 °C, in the original packaging. Protect them from moisture, excessive heat and direct light. Keep the product out of reach of children and do not use after the expiration date.

Naldix is administered orally as a tablet. It can be taken with or without food, but patients should swallow the tablet whole with water and follow the dosing schedule prescribed by their healthcare provider.

The most serious adverse reactions include hepatotoxicity (elevated liver enzymes or liver injury), severe depression or suicidal ideation, and allergic reactions that may progress to anaphylaxis. Patients should report any signs of liver dysfunction, mood changes, or hypersensitivity promptly to their clinician.

Naldix should not be used by individuals currently receiving opioid agonist therapy or who have taken opioids within the past 7–10 days, as it can precipitate acute withdrawal. It is also contraindicated in patients with severe hepatic impairment or known hypersensitivity to naltrexone or any excipients in the formulation.
