Higher quinidine levels in hemodialysis patients warrant dosing caution; leaves open metabolite contributions to antiarrhythmic effects in renal impairment.
What are the steady-state serum levels of quinidine and its active metabolites in cardiac patients with varying degrees of renal function?
Active metabolites of quinidine reach significant serum levels in patients and possess antiarrhythmic activity, suggesting they contribute to the drug's clinical effects, particularly in patients with renal impairment.
Drayer et al. (1978) studied this question.
