Coronavirus disease 2019 (COVID-19) has had a significant impact on human health and economic development over the past two years. Therapeutics in combination with vaccines are critical measures to fight the pandemic. The three areas of drug development are blocking the entry of SARS-CoV-2 into cells, suppressing viral replication inside cells, and regulating the immune system, and important advances have recently been made in those areas. Increasing numbers of neutralizing antibodies and small molecules that show promise have been fully approved or authorized for emergency use, resulting in decreased mortality of patients with COVID-19. The use of therapeutics will have a great impact on formulating and revising public policies to control the pandemic. The pace of lifting of restrictions and economic recovery worldwide will also accelerate in the future. Here, the drugs or agents that have attracted considerable attention and that have led to remarkable progress in the fight against COVID-19 are reviewed.
