UNII
9D2RTI9KYH - DEXTROMETHORPHAN HYDROBROMIDE
|
|
Dextromethorphan is a non-opioid antitussive drug. The major metabolite of dextromethorphan, dextrorphan, binds with high affinity to σ-receptors to produce its antitussive activity without exhibiting the classic opiate effects that occur from binding into μ- and δ-receptors. In larger than therapeutic doses, dextrorphan is also an antagonist of N-methyl-D-aspartate (NMDA) receptors. |

J13S2394HE - QUINIDINE SULFATE

Quinidine increases plasma levels of dextromethorphan by competitively inhibiting cytochrome P450 2D6 (CYP2D6), which catalyses a major biotransformation pathway for dextromethorphan. |
