SARS-CoV-2 Treatment: Current Therapeutic Options and the Pursuit of Tailored Therapy

One year on from the worldwide outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), medicine has made several steps towards increasing the therapeutic options against its treatment. Despite the lack of specific therapies, international societies have introduced new guidelines and launched several trials to test the efficacy of new protocols and drugs. Drug repurposing has been a fundamental strategy to find quick ways to fight the pathogen, even if it is new compounds that are drawing the attention of the scientific community. Tailored therapy should be considered to be a milestone in treatment in order to increase drug efficacy and to reduce drug toxicity. Therefore, both drug characteristics (i.e., pharmacokinetic, pharmacodynamic and safety) and the patient characteristics (i.e., stage of disease, comorbidity, concomitant treatments and the mutation of single nucleotides) could represent the key to achieving this objective. In the present study we performed a narrative review of the pharmacological treatment used to date in the management of coronavirus disease 2019 (COVID-19).
