From what I have read the famotidine(pepcid) is a histamine 2(h2) receptor blocker, but by blocking h2 activation,the virus is less able to enter cells. The h2 inhibition prevents biological channel from letting the virus in. The famotidine does not directly inhibit the channel. from what I read.The dose used in the study was about 80mg 3 times a day. Most pepcid doses for gi work is 40mg per day..higher doses may be used in hypersecretory conditions. 240mg is a high dose. The pepcid was used to decrease inflammatory symptoms from covid but was not tested for clearing of the virus.
Loratidine is a histamine 1 receptor blocker.
Histamine 1 initiates inflammatory actions. So Claritin used for suppressing that. H2 blockers used for suppressing GI acid secretion.

Thank you for the helpful, detailed reminder! I’m saving your info for future use.
