Possible Interaction: Amiodarone and Quinidine

supplement:

Quinidine

Research Papers that Mention the Interaction

Given the predictable pharmacokinetics, it does not require regular monitoring.9 The dose should be reduced by about 1/4 with amiodarone intake, whereas quinidine should be avoided (Pradaxa® insert).

Co-administration of drugs like p-glycoprotein inhibitors amiodarone , verapamil, quinidine and ciclosporin) can increase serum digoxin concentration between 20% and 60%.9 Electrolyte disturbances like hypokalaemia and hypomagnesaemia, induced by diuretic agents and hypercalcaemia can also increase digoxin toxicity.

Amiodarone increased the VT cycle length more than quinidine (85 vs 121 ms, p < 0.05).
The American journal of cardiology  •  1993  |  View Paper
It increased from 323 +/- 39 to 423 +/- 84 msec (n = 11, p less than 0.01) by adding encainide to amiodarone therapy, and it showed a tendency to lengthen when quinidine was added to amiodarone (from 373 +/- 77 to 425 +/- 58 msec; n = 10, NS).
Circulation  •  1991  |  View Paper
Amiodarone in combination with quinidine prevented the induction of ventricular fibrillation and proved effective during a 3-year follow-up period.
Cardiology  •  1988  |  View Paper
Clinically significant drug interactions have been observed with amiodarone and warfarin, digoxin, quinidine and procainamide.
Clinical pharmacokinetics  •  1984  |  View Paper
Clinical toxicity occasionally occurred with the increase in serum levels of quinidine and procainamide, and the dose of these drugs should be decreased when amiodarone is administered concurrently.
The American journal of cardiology  •  1984  |  View Paper
The patient was treated with oral amiodarone which was unsuccessful until combined with quinidine ; this regimen has suppressed recurrence of VT during a four-month period of follow-up.
Pacing and clinical electrophysiology : PACE  •  1984  |  View Paper
Torsades de pointes has been observed when quinidine , propafenone, or mexiletine is given together with amiodarone.
American heart journal  •  1983  |  View Paper
Combined administration of quinidine and amiodarone in a normal volunteer resulted in an increase in plasma quinidine concentration and in QT prolongation, thus confirming the clinical observation of a clinically relevant interaction between the two drugs.
