A response has come from China to the respiratory disease caused by the new coronavirus (SARS-Co V-2) that emerged in December 2019 in this country. Indeed, following the very recent publication of results showing the in vitro activity of chloroquine against SARS-Co V-2, data have been reported on the efficacy of this drug in patients with SARS-Co V-2-related pneumonia (named COVID-19) at different levels of severity. Plaquenil peak How effective against malaria is chloroquine Plaquenil retinopathy is irreversible in most cases. Therefore, preventing the condition through safe dosing is the first priority, and detection of the earliest sign The incidence of HCQ retinopathy is very low. In fact, HCQ is estimated at having a 0.5% incidence of retinal toxicity after 5 years of therapy. 5, 6 Retinal toxicity secondary to HCQ is irreversible and can continue to progress following cessation of therapy. 7 Prompt screening and serial monitoring. Ocular Irreversible retinal damage has been observed in some patients who had received hydroxychloroquine sulfate. Significant risk factors for retinal damage include daily doses of hydroxychloroquine sulfate greater than 6.5 mg/kg 5 mg/kg base of actual body weight, durations of use greater than five years, subnormal glomerular filtration, use of some concomitant drug products such as tamoxifen citrate and concurrent macular disease. The first results obtained from more than 100 patients showed the superiority of chloroquine compared with treatment of the control group in terms of reduction of exacerbation of pneumonia, duration of symptoms and delay of viral clearance, all in the absence of severe side effects Regarding viruses, for reasons probably partly identical involving alkalinisation by chloroquine of the phagolysosome, several studies have shown the effectiveness of this molecule, including against coronaviruses among which is the severe acute respiratory syndrome (SARS)-associated coronavirus. Thus, following the in vitro results, 20 clinical studies were launched in several Chinese hospitals.
