Brief Summary
The goal of this study is to evaluate the efficacy and safety of emetine administered orally for symptomatic patients aged 18-65 years infected with the dengue virus. The main questions it aims to answer are:
- 1.Does emetine reduce 28-day mortality or progression to severe dengue (severe plasma leakage, severe bleeding, or severe organ involvement)?
- 2.What are the safety outcomes of emetine, including serious adverse events and toxicities?
- 3.Take either 6mg emetine, 12mg emetine, or a placebo pill for 7 consecutive days as part of the treatment regimen.
- 4.Have blood samples taken for at least 5 days to monitor viral load, inflammatory markers, and safety parameters.
- 5.Be monitored by healthcare staff for daily vital signs and symptoms for clinical assessments for 28 days.
