Continuous venovenous hemodiafiltration along with charcoal hemoperfusion for the management of life-threatening lercanidipine and amlodipine overdose.
Overdose with calcium channel blockers is uncommon, but is associated with high mortality. The management includes fluid resuscitation, calcium gluconate, glucagon, vasopressors, and high-dose insulin-euglycemia therapy. We describe a rare case of massive overdose of lercanidipine with shock, refractory to conventional therapies and multi-organ failure. Charcoal hemoperfusion with continuous venovenous hemodiafiltration was then used successfully and the patient showed remarkable recovery.

Management of lercanidipine overdose with hyperinsulinaemic euglycaemia therapy: case report.
This case report describes the first reported overdose of the dihydropyridine calcium channel blocker (CCB) lercanidipine. A 49 yr old male presented to the Emergency Department 3 hrs after the ingestion of 560 mg of lercanidipine. In the department he had a witnessed seizure within 15 minutes of arrival attributed to the overdose. Following immediate recovery of consciousness after the seizure, he had refractory hypotension and bradycardia which failed to respond to fluid resuscitation, glucagon therapy, and intravenous calcium. He went on to require vasopressor support with noradrenaline and was treated with high dose insulin therapy which was successful in achieving cardiovascular stability. Vasopressor therapy was no longer required within one half life of lercanidipine, and the total stay on intensive care was one day before transfer to a ward.Calcium channel blocker overdose is an uncommon but life-threatening overdose. Treatment for severe toxicity is similar to b-blocker overdose. Hypotension is treated with intravenous fluid therapy, intravenous calcium and possibly glucagon with vasopressor or inotropic support as required. Atropine is used to attempt reversal of bradycardia. High doses of intravenous insulin with intravenous dextrose as required (hyperinsulinaemic euglycaemia or HIET), has also been successfully reported. Experimental animal data suggests that HIET is of benefit and potentially superior to fluid therapy, calcium, glucagon and potentially vasopressor therapy. HIET effectively and sustainably reverses hypotension, bradycardia and improves myocardial contractility and metabolism. Current advice in calcium channel blocker overdose is to begin therapy early in toxicity, starting with a 1.0 IU/kg insulin bolus followed by an infusion of 0.5 IU/kg/hr of insulin and dextrose as required titrated to clinical response.

Calcium channel antagonist exposures reported to the Poisons Information Center Erfurt.
We investigated the toxicity profile of the three main groups of calcium channel antagonists (CCA) and compared mixed CCA exposures (CCA plus another drug) with mono CCA exposures.. All CCA exposures reported to the PIC Erfurt from 2000 to 2009 were analyzed retrospectively.. In total, 727 (230 mono and 497 mixed) CCA exposures were registered. Although CCA exposures increased almost twofold from 56 in 2000 to 108 in 2009 their relative frequency to all exposures remained constant. The five CCAs most frequently involved in exposures were the five most frequently prescribed ones in Germany over the same period. In mono and mixed CCA exposures, none or minor symptoms were most often seen with dihydropyridines (mono: 84.7%; mixed: 68.0%) followed by diltiazem (mono: 71.4%; mixed: 62.5%) and verapamil (mono: 57.1%; mixed: 50.0%). Highest rates of moderate (mono: 8.6%: mixed: 20.2%) and severe symptoms (mono: 18.6%; mixed: 23.7%) were observed after verapamil ingestions. Death most frequently occurred with diltiazem (mono: 28.6%; mixed: 12.5%). Rates of moderate symptoms were higher in mixed (13.3%) than in mono CCA exposures (4.8%). No distinct differences were seen regarding the relative frequency of none or minor symptoms, severe symptoms, and death between mono and mixed CCA exposures.. Exposures to verapamil more often resulted in moderate and severe symptoms than with dihydropyridines. Death mainly occurred with diltiazem. Moderate symptoms were more frequent in mixed than in mono CCA exposures. The frequency of CCAs involved in exposure was related to their prescription.
