'"`UNIQ--vote-00001580-QINU`"' First FDA-approved treatment for PBA. The 10 mg quinidine daily dose is far below antiarrhythmic levels but sufficient to nearly fully inhibit CYP2D6, the basis of the combination's pharmacokinetic rationale'"`UNIQ--ref-00001581-QINU`"'. (1) ·
µ-opioid agonism (1)
uses:
None (50) ·

Dextromethorphan substantially prolonged by quinidine's CYP2D6 inhibition (typical extensive metabolizers see ~10× higher AUC); quinidine ~6-8 hours'"`UNIQ--ref-00001583-QINU`"' (1) ·
Estimated ~12–17 h (some sources cite up to ~21 h); active metabolites prolong effect. (1) ·
Tramadol ~5-7 hours (M1 metabolite ~9 hours); acetaminophen 1-3 hours'"`UNIQ--ref-00001530-QINU`"' (1)
bioavailability:
pregnancy:
None (52) ·
Avoid. Benzodiazepines are associated with neonatal sedation, floppy-infant syndrome, and withdrawal; teratogenic signal weak but non-zero. Designer benzo with no safety data, assume worst-case. (1) ·
Avoid; neonatal opioid withdrawal documented.<sup class="pcp-cn" title="This claim needs a citation.">[[[Pharmacopedia:Citation needed|citation needed]]]</sup> (1) ·
Limited data; quinidine has been used in pregnancy as antiarrhythmic.<sup class="pcp-cn" title="This claim needs a citation.">[[[Pharmacopedia:Citation needed|citation needed]]]</sup> (1)
legal:
None (53) ·
[[USLegal:Prescription only|Rx-only]] in US. Caution with QT-prolonging medicines (quinidine itself is class IA antiarrhythmic, and the dose here, though sub-antiarrhythmic, still contributes to QT)'"`UNIQ--ref-00001585-QINU`"' (1) ·
[[USLegal:Schedule IV|Schedule IV controlled substance]] in US (tramadol was reclassified from non-controlled to Schedule IV in 2014 after recognition of dependence risk) (1)
