A medicine composed of two antivirals, which is administered orally in the form of a pill before maintaining a risky sexual relationship, with the aim of preventing the transmission of HIV, has received the approval of the United States Medicines Agency (FDA), and has become the first preventive treatment that reduces the risk of becoming infected with HIV.

It is a drug that was already being used to control the AIDS virus in infected people, but now it is also allowed to be used as a prophylactic measure to reduce the risk of infection. However, the US health authorities have already warned that this pill is not a substitute for other protection methods, such as preservative.

In two previous clinical trials the use of this drug was able to reduce the cases of infection by 42% in a study in which healthy men were involved in homosexual relationships, and in 75% when the volunteers were heterosexual couples in which one of the two were infected with HIV and the other was not. This significant difference in the percentage of infection reduction could be due, although the FDA does not specify it, that anal sex is more aggressive for mucous membranes than vaginal.

Experts point out that the effectiveness of the new method is, in any case, less than that offered by the use of condoms - which exceeds 95% - and that is why some have expressed their disagreement with the approval of the drug because they believe it could be transmitted to the population the false message that it is a valid substitute for the condom.

However, the preventive pill is not indicated for the general population, nor does it pretend to replace the condom, but it is directed to certain groups, such as people who practice prostitution in violent environments where it is not always possible to use the drug. condom, for which although it will not constitute a total protection against the virus, it can reduce the risk of infection.
