Spontaneous idea: magnesium and hydroxychloroquine

The most limiting adverse effect of hcq is cardiac arrythmia caused by qt time prolongation driving torsade de pointes, ventricular fibrillation and asystolic death, ultimately.

I remembered mgso4 is drug of choice in tdp, adjusting the qtc to normal.

Since my best bet since 02/2020 is magnesium, my brain cell said 10 in ago WOW.

The literature on Mg AND hcq/cq shows only binding of drug to magnesium particles i.e. in antacids, but no prophylactic use to circumvent this fnctional toxicity:

My bigger to do list is effects of Mg on QTc time prolongation as it is an established high-efficiency drug.

Tomorrow we will know if Hydroxychloroquine could be made a safe drug by oral magnesium substitution - with phased application of mg and hcq bc inactivation of hcq by mere binding each other.
