The HIV virus and the medical condition it causes (AIDS) are two terms known to all of us, since it is a sensitive issue with many books, documentaries and shows created about the disease. Since it is an extremely serious condition that eventually leads to death, we must recognize the progress that science has made in the past few years in an effort to hold it in check and block its development in the patient’s body.
In this article we are going to list the most efficient categories of drugs that have been invented so far and are currently being used as weapons in the fight against a very resilient opponent that is affecting the lives of millions of people around the world.
Non-nucleoside reverse transcriptase inhibitors (NNRTIs)
This category includes chemical substances that target and bind to a specific enzyme called reverse transcriptase, one that allows the HIV virus to copy itself. After binding, NNRTIs reverse the whole procedure.
The most common drugs in this category are Sustiva, lntelence and Viramune.
Nucleoside reverse transcriptase inhibitors (NRTIs)
Here, scientists have created a more direct approach to the virus. NRTls try to block the operation of the aforementioned enzyme completely. There are well known medical products that can be found in this group, some of which are Epivir, Viread, Ziagen, Videx, Emtriva, Retrovir.
Protease inhibitors (Pls) and integrase inhibitors
The logic behind the function of these two is basically the same as the previous ones. Both of the inhibitors block two different enzymes, protease and integrase, in order to stop the HIV virus from cloning itself.
Some of the available drugs are Vitetka, Lexiva and lnvirase.
Entry inhibitors and fusion inhibitors
We are now moving from the prevention of the increase in the virus numbers inside the patient’s body to the blocking of HIV entering the cells. These two inhibitors ‘shield’ the user’s cells not allowing the virus to enter them by blocking specific proteins that it requires to bind to before being able to invade a cell. Selzentry and Fuzeon are the two best options for this type of medication.
The final category does not include drugs but instead a number of products that are used in combination with the anti-HIV drugs and enhance their effectiveness. Tybost is the one administered for the time being.
Thanks to the constant advancements of modern medicine, HIV/AIDS – also remains a deadly condition – doesn’t kill a person within months as it used to. Nowadays, a person who is early diagnosed and starts taking the necessary medicaments can live decades with HIV.
