Naltrexon Molteni (Naltrexone Hydrochloride)

Naltrexone, the active ingredient in Naltrexon Molteni, is an opioid antagonist presented as an oral tablet for oral use. It is employed in the management of alcohol dependence and opioid dependence to reduce cravings and block the effects of opioids. It is indicated for adult patients who require support in maintaining abstinence from alcohol or opioids.

GNH USA supplies Naltrexon Molteni as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, adhering to EU regulatory standards.

Naltrexone is an opioid antagonist used in the treatment of substance‑use disorders.

Alcohol dependence: assists patients in maintaining abstinence by reducing cravings and blocking alcohol‑related reward pathways. Opioid dependence: blocks opioid receptors to prevent euphoria and support detoxification. Prevention of opioid relapse: diminishes the risk of relapse by attenuating the reinforcing effects of opioids.

Naltrexone may cause a range of adverse reactions, which are generally categorized by frequency and severity.

Common Side Effects: - Nausea - Headache - Dizziness - Fatigue - Insomnia - Abdominal pain

Serious or Rare Side Effects: - Hepatotoxicity (elevated liver enzymes, hepatitis) - Severe allergic reactions (rash, angioedema, anaphylaxis) - Depression or suicidal thoughts - Severe rash or skin reactions - Hepatic failure - Acute withdrawal precipitated in opioid‑dependent patients

When prescribing Naltrexon Molteni, clinicians should consider several safety precautions.

Liver function monitoring: assess baseline hepatic enzymes and repeat periodically. Contraindication in acute hepatitis: avoid use in patients with active liver disease. Avoid in opioid‑dependent patients without detoxification: risk of precipitated withdrawal. Pregnancy and lactation: use only if potential benefit outweighs risk. Drug‑induced hepatotoxicity: discontinue if transaminases rise >3× ULN. Store at room temperature: keep in original container, protect from moisture and light.

Naltrexone can interact with other medicines, affecting efficacy or safety.

Major Interactions (Avoid): - Opioid analgesics: may precipitate withdrawal and reduce analgesia. - Disulfiram: increased risk of hepatotoxicity. - Methadone or buprenorphine: antagonism may cause loss of opioid effect.

Moderate Interactions (Monitor Closely): - CYP3A4 inhibitors (e.g., ketoconazole): may increase naltrexone levels. - CYP3A4 inducers (e.g., rifampin): may reduce efficacy. - Alcohol: concurrent use may exacerbate liver toxicity.
