Introduction:
Though there is currently no approved treatment for COVID-19, potential
medications include lopinavir and doxycycline. Lopinavir is a
broad-spectrum protease inhibitor successfully used during the SARS
outbreak. Doxycycline is an antibiotic with immunomodulatory effects,
which successfully treats dengue hemorrhagic fever. Comparing lopinavir
combined with doxycycline with other commonly implemented COVID-19
treatment regimens is of medical significance.
