The most prominent manifestation of overdosage is likely to be excessive prolongation of the QT interval. There were 506 patients in the two DIAMOND studies who had atrial fibrillation (AF) at entry to the studies (249 randomized to Dofetilide and 257 randomized to placebo). Patients with severe renal impairment (creatinine clearance <20 mL/min) were not included in clinical or pharmacokinetic studies (see CONTRAINDICATIONS). Physicians, in consultation with their patients, may therefore in some cases choose doses lower than determined by the algorithm. As shown, both the probability of a patients remaining in sinus rhythm at six months and the change in QTc from baseline at steady state of dosing increased in an approximately linear fashion with increasing dose of Dofetilide. The oral bioavailability of dofetilide is >90%, with maximal plasma concentrations occurring at about 2-3 hours in the fasted state.
