Researchers are looking into whether high doses of famotidine could be used to treat COVID-19 patients. Business Insider reports that Famotidine is the active ingredient in the heartburn medication Pepcid. A clinical trial is currently underway, with researchers aiming to recruit 1,200 patients. The trial is investigating if high doses of famotidine help critically ill coronavirus patients survive. Researchers are using a dose that's nine times the amount of famotidine typically used to treat heartburn. Researchers note that there's no evidence yet from the trial that suggests famotidine is helping.
