Procainamide is metabolized to napa
Procainamide Is Metabolized To Napa. Monitor patients closely for signs and symptoms of methemoglobinemia if coadministration is necessary. Possible side effects include a lupus-like reaction which is more common in slow. The half-life of procainamide is 25 to 5 hrs and the maximum dose in current recommendations is 17 mgkg. Trimethoprim is metabolized in vitro to 11 different metabolites of which five are glutathione adducts and six are oxidative metabolites including the major metabolites 1- and 3-oxides and the 3- and 4-hydroxy derivatives.
Procainamide Unchanged In Urine 59 24 Fast 17 From slidetodoc.com
As a result of this rapid eliminationand a narrow margin between concentrations required to produce efficacy and those producing toxicity. Procainamide is less likely to induce TdP due to its predominant Na blocking effect. This compound is then excreted as NAPA. Procainamide is pharmacokinetically dosed with a therapeutic range between 4-12mcgml. However it can induce TdP in patients with renal dysfunction or in rapid acetylators through its active metabolite N-acetyl procainamide NAPA that has a potent K blocking effect Olshansky et al. The half-life of procainamide is 25 to 5 hrs and the maximum dose in current recommendations is 17 mgkg.
SEPTRA specifically the trimethoprim component can interfere with a serum methotrexate assay as determined by the competitive binding protein technique.
Bactrim specifically the trimethoprim. Procainamide is eliminated by renal excretion and by N-acetylation to NAPA. The increased procainamide and NAPA plasma concentrations that resulted from the pharmacokinetic interaction with trimethoprim are associated with further prolongation of the QTc interval. The increased procainamide and NAPA plasma concentrations that resulted from the pharmacokinetic interaction with trimethoprim are associated with further prolongation of the QTc interval.

As such clinicians may consider decreasing the dosing or frequency of procainamide in cases of hepatic.

Procainamide is pharmacokinetically dosed with a therapeutic range between 4-12mcgml. Additionally coadministration of chloroprocaine with oxidizing agents such as sulfonamides may increase the risk of developing methemoglobinemia. PABA antagonized the effects of sulfonamides.

50 of the drug is cleared renally and 50 is cleared hepatically to the active metabolite NAPA which is actually its own antiarrythmic drug that can be grouped in class III. The increased procainamide and NAPA plasma concentrations that resulted from the pharmacokinetic interaction with trimethoprim are associated with further prolongation of the QTc interval. Procainamide is metabolized hepatically via acetylation to form N-acetyl procainamide NAPA via a substrate of CYP2D6. Procainamide is eliminated by renal excretion and by N-acetylation to NAPA. 54 Likes 13 Comments - UCLA VA Physiatry Residency uclava_pmrresidency on Instagram.
