Famotidine for COVID-19
26th treatment shown to reduce risk in October 2021, now with p = 0.00028 from 30 studies, recognized in 2 countries.
No treatment is 100% effective. Protocols combine treatments.
5,100+ studies for 110 treatments. c19early.org
RCT 50 recovered COVID-19 patients evaluating the efficacy of famotidine for improving cognitive impairment, depression and anxiety. At 6 and 12 weeks, the famotidine group had significantly greater improvements in MMSE (Mini-Mental State Examination) and MoCA (Montreal Cognitive Assessment) scores compared to placebo, indicating better cognitive function. The famotidine group also had slightly greater reductions in HAM-D (Hamilton Depression Rating Scale) and significant reductions in HAM-A (Hamilton Anxiety Rating Scale), suggesting improvements in depression and anxiety symptoms. There were no differences in adverse events between groups. In summary, this double-blind RCT found that famotidine significantly improved cognitive impairment and anxiety in patients recovering from COVID-19, with a minor improvement for depression, without statistical significance. The treatment was well-tolerated.
