सारांश
Cimetidine increases dofetilide plasma concentrations, with greater effect at higher cimetidine doses, and raises the risk of QT prolongation and torsades de pointes. Dofetilide labeling contraindicates concomitant cimetidine. Patients with renal impairment are especially vulnerable.
इस इंटरैक्शन का सरल भाषा में अर्थ
Cimetidine and Dofetilide are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Cimetidine belongs to Gastrointestinal Tract; Dofetilide belongs to Cardiovascular.
ऐसा क्यों होता है
Cimetidine inhibits renal tubular cationic secretion (OCT2/MATE) and possibly CYP3A4, reducing dofetilide renal clearance and increasing exposure.
क्या करें
Do not co-administer. Use an alternative acid suppressant such as a proton pump inhibitor, or famotidine, which is not known to share this effect.
