Methadone Thornton & Ross (Methadone Hydrochloride)

Methadone acts as a full agonist at mu‑opioid receptors, producing analgesia and suppressing opioid cravings. Its additional NMDA‑receptor antagonism may help mitigate opioid tolerance and treat certain neuropathic pain components.

The dose of methadone is individualized. A qualified prescriber determines the appropriate amount based on the patient’s clinical condition, prior opioid exposure, and response to therapy. Dosing may be adjusted during treatment to achieve optimal effect while minimizing adverse reactions.

Methadone can cross the placenta and be present in breast milk. Use during pregnancy or lactation should only occur under specialist guidance, weighing potential benefits for the mother against possible risks to the fetus or infant.

Methadone offers a longer half‑life than many short‑acting opioids, allowing once‑daily dosing and stable plasma levels. Compared with buprenorphine, methadone is a full mu‑opioid agonist, which can provide stronger analgesia but requires stricter monitoring for respiratory depression and cardiac effects.

Methadone should be stored at ambient temperature, below 25 °C, in its original packaging. Protect it from moisture, excessive heat and direct sunlight to maintain potency and stability.

Methadone is taken orally, usually as a tablet or liquid, and should be swallowed whole with water. Doses are typically administered once daily, but the exact schedule is determined by the prescribing clinician.

The most serious risks include respiratory depression, especially after dose escalation or when combined with other depressants, and QT‑interval prolongation that can lead to life‑threatening arrhythmias. Regular monitoring of breathing and cardiac function is essential.

Methadone is contraindicated in individuals with known hypersensitivity to the drug, those with severe uncontrolled respiratory depression, and patients with certain cardiac conditions that predispose to QT prolongation. It should also be used with caution in patients with significant hepatic impairment.
