Ivermectin has been trialed also and has been available on experimental basis even in Europe - and it was found ineffective and is not recommended anymore.
Also similar non-randomized evidence was strongly suggesting that hydroxychloroquine was very effective (e.g. Raoult in France) - until proper randomized trials found it was not effective at all.
So you really can't rely on such evidence. That someone gets better after they got some drug doesn't automatically mean they got better because of the drug. In the absence of controls for other factors (other drugs, spontaneous recovery on their own, etc.) it only means that the drug didn't make their affliction worse.
Not everything has to be immediately a conspiracy of big pharma (or worse).
