With less information on AIDS infections and experts, this pill achieves this achievement: pre-exposure prophylaxis, known as PrEP.
If taken every day, PrEP reduces the chance of hiring through sexual intercourse by more than 90% or 70%, using sterilized needles or people, according to Centers for Disease Control and Prevention. Preventing United States Disease (CDC in English).
Gilead Sciences pharmaceutical companies launched in 2012 under the brand Truvada.
Three years later, the World Health Organization (HIV) in HIV-positive groups was recommended to prevent HIV prevention, such as homosexuals, bisexuals and women, sex workers or sex workers. someone infected with this virus.
But the results that are already seen in the developed countries have fared away the high prices of this treatment from the weakest areas.
Chile, for example, is one of the 10 countries in the world, since new cases of HIV patients have grown by more than 50% between 2010 and 2017 in accordance with the United Nations Joint HIV / AIDS UNAIDS.
And where PrEP costs US $ 575 and US $ 645 per month, according to the press in the country.
In the first quarter of 2019, however, the government will distribute it free of charge as a national anti-AIDS plan for cancer, the new infections between 2010 and 2017 have doubled, according to the Chilean Public Health Institute (ISP).
But how does it work?
PrEP has both emtricitabine and tenofovir, two drugs used in antiretroviral drugs, which reduce blood circulation and prevent multiplication.
It does not make a vaccine because it does not cause antibodies, but the daily need is necessary to prevent emtricitabine and tenofovir blood when implanted at the time of infection and HIV. CDC explains. Website
However, PrEP is not everyone. Before it is taken, the patient's virus must be discarded when it is infected. It is also necessary to check the good state of the kidneys and liver because this pill can cause the disorders of these organs.
Experts recommend reducing the risk of contracting HIV, the treatment may cause side effects, such as nausea, stomach or headaches, and, in more cases, the accumulation of lactic acid.
Also, those with hepatitis B should be especially careful, if Truvada is used and treatment is stopped, it is likely that hepatitis is worse.
It is not 100% infallible
Accepting PrEP does not mean that other methods of prevention can be predicted. This pill does not protect against other sexually transmitted diseases, such as gonorrhea, syphilis or herpes genitalia.
It is not 100% inflexible. Although rare, they have contracted Truvada in at least five cases in the liver, and in other cases, patients could not completely get rid of the virus before taking the pill. It includes a portal specialized in AIDS.
There are few exceptions among thousands of people who use PrEP. However, the treatment must be carried out with other prevention methods, such as condoms and periodic HIV tests.
