Key points:
- Reports demonstrated an association between COVID-19 and olfactory
dysfunction
- Olfactory dysfunction causes an increase in intracellular calcium
concentration
- Pentasodium diethylenetriamine pentaacetate has ability to decrease
calcium concentration in the nasal secretion
- Intranasal pentasodium diethylenetriamine pentaacetate may be a useful
therapy for olfactory dysfunction
- Significant improvement was observed from functional anosmia to
hyposmia
