Advances in Clinical Research on PrEP drug

Pre-exposure prophylaxis (PrEP) is a preventive measure that involves the use of antiretroviral drugs to reduce the risk of HIV infection in individuals who are not infected but are at high risk of exposure. After taking PrEP medication, the active ingredients enter the cells and interrupt the reverse transcription process during HIV invasion, inhibiting the synthesis of HIV viral DNA from viral RNA, and preventing HIV from entering the cell nucleus, thus avoiding HIV infection. Continuous use of PrEP medication prevents the virus from progressing to the established stage of infection and spreading in the body. It is important to note that PrEP is not a vaccine, and the body does not produce HIV antibodies as a result of using PrEP. Therefore, regular oral administration is necessary to achieve its preventive effect. Taking a pill before engaging in sexual activity does not effectively block HIV transmission.

Can PrEP effectively prevent HIV?

When taken regularly and consistently, PrEP medication can effectively prevent HIV. According to the 2011 iPrEx clinical trial conducted among gay and bisexual men in the United States, PrEP demonstrated a preventive efficacy of 96%-99% in individuals who were highly adherent to the medication regimen. However, if the medication is not taken consistently or in sufficient doses, its effectiveness diminishes. Research has also shown that for heterosexual individuals with an HIV-positive partner, PrEP can reduce the risk of infection by up to 75%. It is important to note that the effectiveness of PrEP depends on the adherence of the individual taking it. Strict adherence to the medication regimen is necessary to minimize the risk of HIV infection.

It is worth noting that PrEP provides biomedical protection against HIV and has limitations in preventing drug-resistant strains of the virus. Therefore, the use of PrEP medication should be accompanied by the consistent use of condoms to reduce the risk of HIV and other sexually transmitted infections. Additionally, individuals taking PrEP medication should undergo sexual health and HIV testing every three months, and their medication adherence and high-risk behaviors should be closely monitored in the long term.
