What is famotidine used for?

Currently available evidence suggests that famotidine does not cause cancer. This issue arose after over-the-counter and prescription ranitidine (the previous ingredient of Zantac®) was found to contain a potentially cancer-causing contaminant called NDMA. When this was discovered in 2020, the manufacturing and sale of all ranitidine products was discontinued in the United States. Since NDMA is not present in famotidine, Pepcid® and other products containing famotidine were not affected by this action, and famotidine is still available for sale in the United States. Zantac® now contains famotidine instead of ranitidine.

Famotidine for Treatment of COVID-19: Hope or Hype? The Most Comprehensive Review

Can a popular heartburn drug Pepcid help fight SARS-CoV-2? Until the results of randomized controlled trials have been collected, it makes absolutely no sense to place big bets on Pepcid. What to say, if the COVID-19-suffering pandemic world was unequivocally confident in the therapeutic efficacy of the antimalarial hydroxychloroquine, but the results showed its utter uselessness in the fight against the new coronavirus SARS-CoV-2.

Famotidine, Histamine, and the Coronavirus

The most straightforward explanation of the apparent famotidine activity as a COVID-19 therapy is that the drug acts via its antagonism or inverse-agonism of histamine signaling and via its arrestin biased activation—all a result of its binding to H2. If true, then it is reasonable to infer that a SARS-CoV-2 infection that results in COVID-19 is at least partially mediated by pathologic histamine release.
