Doctors Recommend A New Drug For The Prevention Of HIV Infection

Doctors Recommend A New Drug For The Prevention Of HIV Infection.
Should relations in jeopardy of contracting HIV because they have dodgy congress record a pill to prevent infection, or will the medication hearten them to take even more sexual risks? After years of controversy on this question, a new international con suggests the medication doesn't lead rank and file to stop using condoms or have more sex with more people. The scrutiny isn't definitive, and it hasn't changed the affronted by of every expert fav-store.net. But one of the study's co-authors said the findings verify the drug's use as a street to prevent infection with HIV, the virus that causes AIDS.

And "People may have more partners or take a break using condoms, but as well as we can tell, it's not because of taking the stupefy to prevent HIV infection ," said look co-author Dr Robert Grant, a major investigator with the Gladstone Institute of Virology and Immunology in San Francisco. The medication in into question is called Truvada, which combines the drugs emtricitabine and tenofovir health. It's normally utilized to take out relatives who are infected with HIV, but inquiry - in homosexual and bisexual men and in straight couples with one infected wife - have shown that it can lower the risk of infection in nation who become exposed to the virus through sex.

However, it does not take for a ride the risk of infection. The US Food and Drug Administration approved the slip for frustration purposes in 2012. Few people seem to be taking it for tabooing purposes, however. Its manufacturer, Gilead, has disclosed that about 1700 clan are taking the drug for that sense in the United States, Grant said. In the additional study, researchers found that expected rates of HIV and syphilis infection decreased in almost 2500 men and transgender women when they took Truvada.

The chew over participants, who all faced spacy peril of HIV infection, were recruited in Peru, Ecuador, South Africa, Brazil, Thailand and the United States. Some of the participants took Truvada while others took an pacific placebo. Those who believed they were taking Truvada "were just as safe-deposit as everybody under the sun else," Grant said, suggesting that they weren't more probably to an end using condoms or be more unthinking because they believed they had supplementary safeguard against HIV infection.

Grant said the purpose of the study allows scientists to better allow the choices that participants make. The reading is limited, however, because the researchers recruited participants a substitute of waiting for people to come to them. For that reason, it's out of the question to know if folk will seek out Truvada to take new levels of hazard by, say, no longer using condoms. There are many skeptics, including the AIDS Healthcare Foundation, who fears that the soporific will purely promote people to make riskier decisions in admiration to sex.

One of these skeptics is Arleen Leibowitz, a professor emeritus of clientele policy at the Luskin School of Public Affairs at the University of California, Los Angeles. She said the mull over shows that many males and females failed to necessitate Truvada as prescribed and often didn't carry enough to be protected from HIV. That raises the plan that some people would take risks because they feel they're protected when they actually aren't, she noted.

Leibowitz also said some of the statistics in the ponder are shady because they don't include enough participants. And she said the participants may have lied about their sexual intercourse lives to satisfy the people who interviewed them. "We'll get it a lot when its use becomes more general. But it's disturbing to do experiments on the general population".

For the moment, she said, the antidepressant may be appropriate for some patients who need protection money from HIV, but doctors should be cautious and make convinced their patients take the medication. The research is published in the Dec 18, 2013 online version of the journal PLoS One african. In other HIV/AIDS news, a original study - also published in PLoS One - reports that 20-year-old men infected with HIV in the United States and Canada can envision to breathe almost as sustained as the generalized population and make it, typically, to their initial 70s.
