COVID-19 Treatment Clinical Evidence

COVID-19 involves the interplay of 400+ viral and host proteins and factors, providing many therapeutic targets. c19early analyzes 6,000+ studies for 210+ treatments—over 17 million hours of research. Only three high-profit early treatments are approved in the US. In reality, many treatments reduce risk, with 25 low-cost treatments approved across 163 countries.

Naso/oropharyngeal treatment Effective Treatment directly to the primary source of initial infection.
Healthy lifestyles Protective Exercise, sunlight, a healthy diet, and good sleep all reduce risk.
Immune support Effective Vitamins A, C, D, and zinc show reduced risk, as with other viruses.
Thermotherapy Effective Methods for increasing internal body temperature, enhancing immune system function.
Systemic agents Effective Many systemic agents reduce risk, and may be required when infection progresses.
High-profit systemic agents Conditional Effective, but with greater access and cost barriers.
Monoclonal antibodies Limited Utility Effective but rarely used—high cost, variant dependence, IV/SC admin.
Acetaminophen Harmful Increased risk of severe outcomes and mortality.
Remdesivir Harmful Increased mortality with longer followup. Increased kidney and liver injury, cardiac disorders.

Lercanidipine may be beneficial for COVID-19 according to the studies below. COVID-19 involves the interplay of 400+ viral and host proteins and factors providing many therapeutic targets. Scientists have proposed 11,000+ potential treatments. c19early.org analyzes 210+ treatments. We have not reviewed lercanidipine in detail.

Kumar et al., Advancements in the development of antivirals against SARS-Coronavirus, Frontiers in Cellular and Infection Microbiology, doi:10.3389/fcimb.2025.1520811

Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) caused an outbreak in 2002-2003, spreading to 29 countries with a mortality rate of about 10%. Strict quarantine and infection control methods quickly stopped the spread of the disease. Later research showed that SARS-CoV came from animals (zoonosis) and stressed the possibility of a similar spread from host to human, which was clearly shown by the COVID-19 outbreak. The COVID-19 pandemic, instigated by SARS-CoV-2, has affected 776 million confirmed cases and more than seven million deaths globally as of Sept 15, 2024. The existence of animal reservoirs of coronaviruses continues to pose a risk of re-emergence with improved fitness and virulence. Given the high death rate (up to 70 percent) and the high rate of severe sickness (up to 68.7 percent in long-COVID patients), it is even more critical to identify new therapies as soon as possible. This study combines research on antivirals that target SARS coronaviruses that have been conducted over the course of more than twenty years. It is a beneficial resource that might be useful in directing future studies.

Ghahremanpour et al., Identification of 14 Known Drugs as Inhibitors of the Main Protease of SARS-CoV-2, bioRxiv, doi:10.1101/2020.08.28.271957

AbstractA consensus virtual screening protocol has been applied to ca. 2000 approved drugs to seek inhibitors of the main protease (Mpro) of SARS-CoV-2, the virus responsible for COVID-19. 42 drugs emerged as top candidates, and after visual analyses of the predicted structures of their complexes with Mpro, 17 were chosen for evaluation in a kinetic assay for Mpro inhibition. Remarkably 14 of the compounds at 100-μM concentration were found to reduce the enzymatic activity and 5 provided IC50 values below 40 μM: manidipine (4.8 μM), boceprevir (5.4 μM), lercanidipine (16.2 μM), bedaquiline (18.7 μM), and efonidipine (38.5 μM). Structural analyses reveal a common cloverleaf pattern for the binding of the active compounds to the P1, P1’, and P2 pockets of Mpro. Further study of the most active compounds in the context of COVID-19 therapy is warranted, while all of the active compounds may provide a foundation for lead optimization to deliver valuable chemotherapeutics to combat the pandemic.
