T8 133-196 Sentence denotes Antiviral therapy is the most important treatment for COVID-19.
T9 197-344 Sentence denotes Among the drugs under investigation, anti-malarials, chloroquine (CQ) and hydroxychloroquine (HCQ), are being repurposed as treatment for COVID-19.
T10 345-522 Sentence denotes CQ/HCQ were shown to prevent receptor recognition by coronaviruses, inhibit endosome acidification, which interferes with membrane fusion, and exhibit immunomodulatory activity.
T11 523-609 Sentence denotes These multiple mechanisms may work together to exert a therapeutic effect on COVID-19.
T12 610-759 Sentence denotes A number of in vitro studies revealed inhibitory effects of CQ/HCQ on various coronaviruses, including SARS-CoV-2 although conflicting results exist.
T13 760-985 Sentence denotes Several clinical studies showed that CQ/HCQ alone or in combination with a macrolide may alleviate the clinical symptoms of COVID-19, promote viral conversion, and delay disease progression, with less serious adverse effects.
T14 986-1146 Sentence denotes However, recent studies indicated that the use of CQ/HCQ, alone or in combination with a macrolide, did not show any favorable effect on patients with COVID-19.
T15 1147-1250 Sentence denotes Adverse effects, including prolonged QT interval after taking CQ/HCQ, may develop in COVID-19 patients.
T16 1251-1542 Sentence denotes Therefore, current data are not sufficient enough to support the use of CQ/HCQ as therapies for COVID-19 and increasing caution should be taken about the application of CQ/HCQ in COVID-19 before conclusive findings are obtained by well-designed, multi-center, randomized, controlled studies.
