Summary
Androgen deprivation therapy such as triptorelin can prolong the QT interval, and methadone has a similar effect. Combined use may increase the risk of torsades de pointes, particularly in patients with other risk factors.
What this interaction means in plain words
Methadone and Triptorelin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Methadone belongs to Musculoskeletal; Triptorelin belongs to Endocrine.
Why it happens
Additive QT prolongation; androgen deprivation alters cardiac repolarization while methadone blocks hERG channels.
What to do
Check a baseline ECG and electrolytes, and repeat the ECG during treatment. Reassess if the QTc rises substantially or the patient develops syncope or palpitations.
