Chloroquine is an ingredient in the 4-aminoquinoline group of drugs, first discovered in 1934 by Hans Andersag and colleagues at Bayer Laboratories. It is on the World Health Organization's list of essential medicines. After many studies and clinical experiments, in 1947, chloroquine was officially put into use to prevent malaria. When malaria parasites enter the body, they live and reproduce in red blood cells or in the liver. And the drug chloroquine has the ability to fight clonal forms of malaria inside red blood cells.
1950 was the time when chloroquine was most widely used in medicine. After that, through clinical experiments, it was found that drug resistance to chloroquine was increasing strongly, so the prevention and treatment of malaria was replaced by other drug groups.
In 1993, people reintroduced chloroquine in the treatment of malaria, showing relatively high clinical efficacy, much higher than that of other drug classes. To avoid drug resistance as happened in the late 1950s, in medicine, chloroquine has been combined with other drug classes in the treatment of malaria.

In a few laboratory studies, the effect of chloroquine has been tested on vero E6 cells in patients infected with SARS - CoV - 2 virus. The results show that chloroquine has the ability to reduces viral replication, so it can be applied clinically to prevent disease progression.
In China, the US, the Netherlands and a number of other countries, the drug has been included in clinical trials in patients who are positive for covid 19 with different degrees of illness. After that, the drug was included in the treatment regimen for pneumonia caused by covid 19, but it is necessary to closely monitor and check the patient's health before giving the patient the drug.
According to the Times of India on March 22, 2020, French scientists have provided a new ray of hope for patients positive for the Covid-19 virus that the combination of antimalarial drugs with antibiotics could be an important weapon in the fight against the Covid-19 virus. Clinical results show that the combination of chloroquine and azithromycin is relatively effective in treating the disease caused by covid 19.
From early March to mid-March 2020, in France, scientists conducted a study by giving 600mg of the drug chloroquine per day to a group of patients infected with covid 19. The patients were closely monitored throughout the process. trial and based on changes in health status to supplement azithromycin.
At the end of the study on 22 patients, the virus was significantly eliminated when using these 2 drugs together. Chloroquine has the ability to reduce or kill viruses, azithromycin is used to treat certain infections in the respiratory tract such as pneumonia, bronchitis. Combining these two drugs together will increase the effect for a better treatment effect.
According to experts, the drugs chloroquine and azithromycin are associated with prolonging the time it takes for the heart to repolarize, thereby helping to delay ventricular repolarization. To complete this process, the heart muscle needs to take longer than usual to recharge between beats.
Therefore, the use of drugs can bring danger to patients, especially in patients with chronic diseases such as liver failure, kidney failure.

In Vietnam, currently, the Ministry of Health has not yet recommended the use of this drug to prevent Covid 19.
In general, chloroquine is a drug used to treat malaria. Currently, many countries around the world have included drugs in the treatment regimens for diseases caused by the Covid-19 virus. The combined use of chloroquine and azithromycin has shown a certain therapeutic effect.
