Since HCQ is widely used for the treatment of Systemic Lupus Erythematosus (SLE) and Rheumatoid arthritis (RA), we will use the pharmacodynamic/pharmacokinetic (PD/PK) data of HCQ to discuss the role of HCQ in COVID-19 treatment. After oral absorption, HCQ is widely distributed in various tissues in the body. According to the results of animal experiments, the tissues with the most HCQ distribution were the lungs, with a concentration of up to 227 times that of plasma, followed by the spleen, liver, and kidney. 1 This finding is similar to another in-vitro study on Although HCQ is safer and more effective than Chloroquine, special attention should be paid to the interaction and side effects when it is used with Azithromycin. Especially in terms of cardiovascular, both HCQ and Azithromycin are likely to cause arrhythmias (such as QT prolongation and torsades de points), and combined use will increase the incidence, which was also observed by Molina. 4 There's no guidance for the treatment of COVID-19 has indicated that the dose of HCQ can be calculated according to body weight and adjusted according to different races. Further studies are needed in the future to provide more comprehensive data. All authors declare no conflict of interest.
