Combining Metoprolol Tartrate and Paroxetine is a major interaction and should generally be avoided without close medical supervision.
The coadministration of metoprolol and paroxetine can lead to a significant increase in metoprolol plasma concentrations. This interaction can result in enhanced beta-blockade effects, potentially causing severe bradycardia, hypotension, or heart block, which may be life-threatening.
Mechanism: Paroxetine is a potent inhibitor of the cytochrome P450 2D6 (CYP2D6) enzyme. Metoprolol is primarily metabolized by CYP2D6, so paroxetine inhibits its metabolism, leading to reduced clearance and increased systemic exposure of metoprolol.
