RCT 60 hospitalized patients in India, showing significantly greater clinical improvement with inhaled sodium bicarbonate.
Nasal and oral inhalation of nebulized 50ml 8.4% sodium bicarbonate for 5 minutes twice daily for 5 days.
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 and reduced systemic side effects (early treatment may be more beneficial).

Effect of 8.4% Soda-Bicarbonate Steam Inhalation on the Course of Disease in Mild to Moderate Cases of Covid-19
Kshitij Mody
Background: A prospective, randomized open label parallel group trial was carried out to evaluate the effect of 8.4% soda-bicarbonate steam inhalation on the course of covid-19 infection in mild to moderate confirmed cases of covid-19. Methods: 30 patients were enrolled and compared with 30 patients in a control group, giving a total sample size of 60 patients. Randomisation was achieved by sealed envelope technique. The 30 patients in the SB group received SB inhalation in addition to all other therapeutic measures as part of covid-19 treatment protocol. The control group was treated according to same treatment protocol, but without SB inhalation therapy. Clinical symptoms and lab markers were recorded on Day 1 and Day 5 of patients' stay at hospital.
Results: Patients receiving 8.4% SB inhalation as part of their treatment showed faster improvement in symptomatology and quicker normalization of inflammatory lab markers.
Conclusion: The results of this study show a highly significant improvement in the clinical picture of covid-19 affected patients treated with inhalations of steam impregnated with 8.4% sodium bicarbonate.
Proportion of subjects showing clinical symptomatic improvement was statistically significantly higher in the SB group as compared to the non-SB group. Proportion of improvement was found to be 73.33 and 26.67 in the SB and non-SB groups respectively (p-value 0.0003). Further studies with a larger patient population can establish further proof for the application of sodium bicarbonate as a useful agent to combat the covid-19 infection.
