Current pharmacological treatments for SARS-COV-2: a narrative review. (Special Issue: Therapeutic targets and pharmacological treatment of COVID-19.)

The novel coronavirus, later identified as SARS-CoV-2, originating from Wuhan in China in November 2019, quickly spread around the world becoming a pandemic Despite the knowledge of previous coronaviruses, such as those responsible for the SARS and MERS-CoV epidemic, there is no drug or prophylaxis treatment to this day The rapid succession of scientific findings on SARS-CoV-2 provides a significant number of potential drug targets Nevertheless, at the same time, the high quantity of clinical data, generated by a large number of rapidly infected people, require accurate tests regarding effective medical treatments Several in vitro and in vivo studies were rapidly initiated after the outbreak of the pandemic COVID-19 Initial clinical studies revealed the promising potential of remdesivir that demonstrated a powerful and specific in vitro antiviral activity for COVID-19 Promising effects appear to be attributable to hydroxychloroquine Remdesivir and hydroxychloroquine are being tested in ongoing randomized trials In contrast, oseltamivir was not effective and corticosteroids are not currently recommended However, few data from ongoing clinical trials are identifying low molecular weight heparins, innate immune system stimulating agents, and inflammatory modulating agents as potential effective agents The authors assume that the current pandemic will determine the need for a systematic approach based on big data analysis for identifying effective drugs to defeat SARS-Cov-2 This work is aimed to be a general reference point and to provide an overview as comprehensive as possible regarding the main clinical trials in progress at the moment
