Clinical experience in an acute coronary syndrome population did not show an increased risk of proarrhythmia or sudden death.Co-administration of Antogin ER 500 mg with digoxin increases the plasma concentrations of digoxin by approximately 1.5-fold and the dose of digoxin may have to be reduced accordingly. The dose of other P-gp substrates may have to be reduced as well when Antogin ER 500 mg Is co-admlnistered. Caution should be exercised when co-adminlstering Antogin ER 500 mg with P-gp inhibitors such as ritonavir or cydosporine.
