24 lip 2023 · Estimates of the elimination half-life of amiodarone vary, depending on how the half-life has been measured and the route of amiodarone administration. After long-term oral therapy, amiodarone has a true elimination half-life between 60 and 142 days [2,3].
All of these findings might indicate that the apparent synergistic antinociceptive effects could depend on the duration of the pain and the pharmacokinetics of the opioid – morphine has a much longer in vivo half life than fentanyl – and the associated development of rapid tolerance .

Amiodarone is eliminated primarily by hepatic metabolism and biliary excretion. 4 A small amount of desethylamiodarone (DEA) is found in the urine. 18. Half-life. The terminal half-life of amiodarone varies according to the patient, but is long nonetheless, and ranges from about 9-100 days. The half-life duration varies according to different ...
2 wrz 2010 · The relatively long plasma elimination half‐life of this drug suggests that once‐daily dosing may be comparable with the current twice‐daily practice. We offer a pharmacokinetic rationale for once‐daily prescribing and suggest that the once‐daily strategy may be comparable to traditional twice‐daily dosing and improve adherence. METHODS.
