RCT 55 mild/moderate patients in China, showing shorter hospitalization with sodium bicarbonate nasal irrigation and oral rinsing. Oral rinse with 5% sodium bicarbonate solution three times daily. Nasal irrigation two times with the solution entering through one nostril and exiting from the other. 30–40mL of solution was used every time and irrigation was performed for at least 30s. Details of randomization are not provided.
Targeted administration to the respiratory tract provides treatment directly to the typical source of initial SARS-CoV-2 infection and replication, and allows for rapid onset of action, higher local drug concentration, and reduced systemic side effects (early treatment may be more beneficial).
hospitalization time, 38.5% lower, relative time 0.61, p < 0.001, treatment mean 7.7 (±4.15) n=23, control mean 12.53 (±5.56) n=32.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
