The paper says clinical tests used both chloroquine and hydroxychloroquine. In discussing the results, they don't seem to differentiate between the two, unless I missed it.

When administering chloroquine, the hydroxy- form is a very long-lasting metabolite.

Yes. I think the half-life is ~ 1-2 months

I have in-laws in Nigeria. We just tipped them off a couple of days ago that now might be a good time to buy some Chloroquine and keep at the house, in case the situation gets worse. This is a commonly known medicine down there, that you can get from pharmacies without prescription.

But based on what we're seeing so far, it seems plausible that this virus prefers cooler northern climates. So hopefully it will turn out to be an unnecessary precaution.

> ... has a cumulative dose of more than 1000 grams. ... woowza a Kg worth of drug !!! this doesn't look correct to me !

This drug accumulates in various tissues, so for retinopathy what matters is the cumulative amount of the drug consumed over time.

oh man ! just like excess of vitamin-d can lead to vitamin-d toxicity, so can this. in my naïveté, i was assuming that excess of it would be just flushed out.

So I’m not seeing mention of this anywhere else chloroquine is being talked about. Chloroquine used to be taken daily in many of the tropical Britain colonies suffering from malaria. chloroquine in the form of quinine is where the gin and tonic drink came from. Quinine mixed with carbonated water was drunk as a prophylactic. The quinine tasted so terrible it had to be cut with something to make it tolerable - gin! Th…

From wikipedia > In the United States, the US Food and Drug Administration (FDA) limits the quinine content in tonic water to 83 ppm[3] (83 mg per liter if calculated by mass), while the daily therapeutic dose of quinine is in the range of 500–1000 mg,[4] and 10 mg/kg every eight hours for effective malaria prevention (2100 mg daily for a 70 kg adult).[5] It is often recommended as a relief for leg cramps, but medica…

Yeah it's pointless now days, modern tonic water is very different to the what they mixed with gin basic when quanine was the purposes rather than a mild flavouring.

Not uniquely. USA is famous for very high prices of essential medicines, and being an expensive country in general.

This was already implied in the question. They're asking why something like ibuprofen is different.

so when it says: "In the early in vitro studies, chloroquine was found to block COVID-19 infection at low-micromolar concentration,"

does this mean it might be a good idea to be taking it regularly to keep from getting covid-19 from contact with surfaces with low concentration of the virus?

In the east coast of Spain we have had great weathee (25+ degrees celsius) and it didn't seem to greatly influence transmission speed :(

Cheapish - as I recall about $300 for 90-day supply of generic hydroxychloroquine if paying cash in US. I mean, not cancer drug spends but if you are on it for life it’s an annoying annual expense.

US drug prices are pretty crazy. A random search in an internet pharmacy shows 100 tablets of 200mg hydroxychloroquine is like 30€ in Germany.

Right, the only medication I sometimes bring from the US now is acetaminophen/paracetamol because it's the only one I've found that's much cheaper there. The rest are probably cheaper in Germany so I would just go there if I needed them.
