التداخل بين فلوكسيتين وبريماكين

QT Interval Prolonging Drugs The pharmacodynamic interaction potential to prolong the QT interval of the electrocardiogram between Primaquine phosphate Tablets and other drugs that effect cardiac conduction is unknown.

If Primaquine phosphate Tablets are used concomitantly with other drugs that prolong the QT interval, close and frequent electrocardiogram monitoring is advised (see PRECAUTIONS , ADVERSE REACTIONS , and OVERDOSAGE ).

Effects of Other Drugs on the Pharmacokinetics of Primaquine Strong CYP2D6 Inhibitors Published clinical and non-clinical reports indicate reduced CYP2D6 activity may decrease the formation of active metabolites of primaquine, which may reduce antimalarial efficacy of Primaquine phosphate Tablets (see CLINICAL PHARMACOLOGY, Pharmacogenomics ).

Where possible, consider alternative medications that are not strong CYP2D6 inhibitors.

Concomitant use of an MAO-A inhibitor in patients with reduced or absent CYP2D6 activity (e.g., strong CYP2D6 inhibitor, CYP2D6 intermediate or poor metabolizer) is expected to increase primaquine exposure which may increase the risk of adverse reactions (see CLINICAL PHARMACOLOGY, Pharmacogenomics ).
