Proposal to use HCQ as an aerosol in order to reach sufficient therapeutic levels at the alveolar epithelial cells. Authors suggest this will reduce adverse drug reactions compared with oral application, and the increase in tolerability enables a broader use for prevention and post-exposure prophylaxis, which would be an advantage especially for high-risk, multi-morbid and elderly patients. Empirical data on self-medication with a one-week aerosol application is presented, showing inhalation was well tolerated.
