Cross-tolerance occurs when tolerance developed to one substance reduces the effects of pharmacologically similar substances acting on the same receptor systems.

Accepted Answer

Its long half-life prevents withdrawal and reduces cravings with once-daily dosing

Answer

Methadone's long half-life of 24–36 hours allows once-daily dosing that stabilizes opioid levels, prevents withdrawal, and reduces cravings without producing significant euphoria at therapeutic doses.

Alcohol withdrawal is potentially fatal due to the risk of tonic-clonic seizures and delirium tremens; opioid withdrawal, while severe, is rarely life-threatening in otherwise healthy adults.
