Also, ion channel blockers (typically used as anti-arrhythmics or anti-hypertensives) may inhibit entry of the virus into host cells:

Perhaps one could slow progression of the disease long enough to allow the immune system to mount an effective defense (antibodies).
That sounds very strange. I'm trying to think of a mechanism that could be involved in blocking endocytosis of the virus... I supposed I can read the paper and see what the authors say.
