There is at least some speculation/hypothesis that diazepam has specific effects on benzo receptors in the heart and interacts with TSPO...what that means, however, I do not know. <br>
Anectodally, when we had a chloroquine case years ago (Ross your case), we used midazolam cont infusion and the patient had a good outcome. <br>
I think I will start with diazepam and if the hospital doesn't have it, then give midazolam?<br>

Are all benzodiazepines created equal for this indication? That is, IF diazepam does something, is there something unique with diazepam and peripheral benzo receptors that may or may not be true for other benzos at those peripheral receptors?<br>

>> I agree with what you stated. In our experience, the most important issues in chloroquine poisoning is to secure the respiratory airways and accelerate cardiac rhythm to be maintained at about 70 /min (to avoid ventricular arrhythmias, without accelerating too much to avoid the intensification of the membrane stabilizing effect). These supportive interventions should be performed based on prognosticators and before the onset of any life‑threatening complication if possible. So that, if any acute cardiac complication occurs ... you can focus your management on the heart without losing time with intubation.<br>

>> The "antidotal" effect of diazepam is really minor. There is a RCT diazepam versus placebo in moderate chloroquine poisoning that showed no significant cardiac/ECG effects of diazepam. <br>
>> Do not use another BZD. It is probable that the protective effect is only related to a co‑ingestion of DZP/chloroquine and not to any post‑administration. The experimental evidence to support diazepam antidotal effects are weak.<br>
>> <br>
>> The recommended protocol is the following: <br>
>> ‑ Intubation and mechanical ventilation<br>
>> ‑ Epinephrine 0,25 µg/kg/min with increasing 0.25 µg/kg/min steps to obtain SBP ≥ 100 mmHg<br>
>> ‑ Diazepam 2 mg/kg in 30 min followed with 2‑4 mg/kg/24h<br>

>> The cardiac toxicity of hydroxychloroquine is importantly lower than that of chloroquine, although we use the same criteria and management.<br>

>> Hello Dr Megarbane<br>
>> Thanks for a great talk today.....I have a question regarding treatment of chloroquine/hydroxychloroquine. You mentioned today that the two most important interventions for managing acute toxicity are intubation and epinephrine. I always thought that it was the diazepam that was the most important part and the epi was only given to manage the hemodynamic effects secondary to high doses of diazepam. <br>
>> <br>
>> I'd love to hear your thoughts on this and I want to be sure that I understood what you said. <br>
>> <br>
>> In a patient with acute overdose of either of the two agents, you would intubate early and start epi (and at what dose?) and what dose/which benzo would you use?<br>
>> <br>
>> Thank you so much for your time and any insight,<br>
