Towards Optimization of Hydroxychloroquine Dosing in Intensive Care Unit COVID-19 Patients

Clin Infect Dis. 2020 Nov 19;71(16):2227-2229. doi: 10.1093/cid/ciaa394.


Hydroxychloroquine (HCQ) appears to be a promising treatment for COVID-19. However, all ongoing clinical trials with HCQ use different dosing regimens, resulting in various concentrations. Pharmacokinetic studies are therefore needed to define the optimal dosing regimen.

Keywords: COVID-19; SARS-Cov2; hydroxychloroquine; intensive care; pharmacokinetic.
