Use of antiretroviral medicines in HIV-1 infection treatment

HIV-1 infection is treated with antiretroviral drugs. These medications target different phases of the HIV life cycle, halting the virus' replication and lessening its negative effects on the immune system. The principles of combination antiretroviral therapy (cART) or highly active antiretroviral therapy (HAART) are followed when antiretroviral medications are used to treat HIV-1. The following describes how these drugs are used to treat HIV-1 infection:

Combination Therapy: As the name implies, HIV treatment entails using several antiretroviral medications, often from various pharmacological classes. For the following reasons, this combination is essential:

Reduced medicine Resistance: If one medicine is used alone to treat HIV, that drug's resistance might quickly develop. It is more difficult for the virus to evolve and develop resistance when medications with various modes of action are combined.

Enhanced Efficacy: Antiretroviral medication classes target several stages of the HIV life cycle. The treatment can more effectively reduce viral replication by taking many medications at once.

Lower Viral Load: By preventing viral replication, the body's viral load is reduced, which strengthens the immune system and slows the spread of disease.

Initial therapy: Three or more antiretroviral medications are commonly provided when a person is first diagnosed with HIV-1 infection and starts therapy. The precise combination will be determined by several variables, such as the patient's viral load, CD4+ T-cell count, other medical problems, potential drug interactions, and personal preferences.

Antiretroviral medication classes include the following and are used in various treatment regimens for HIV-1: 

Nucleoside/Nucleotide Reverse Transcriptase Inhibitors (NRTIs/NtRTIs): These medications prevent HIV from converting its RNA into DNA for replication by inhibiting the reverse transcriptase enzyme. Reverse transcriptase is likewise inhibited by non-nucleoside reverse transcriptase inhibitors (NNRTIs), although they do so through a different method. The protease enzyme, which is necessary for the maturation of fresh virus particles, is blocked by protease inhibitors (PIs).

Inhibitors of Integrase Strand Transfer (INSTIs): INSTIs stop HIV from integrating its DNA into the DNA of the host cell.

Entry Inhibitors: These medications prevent the virus from infecting CD4+ T cells by attacking the viral envelope or entry-related cellular receptors.

Adherence: For antiretroviral therapy to be effective, patients must adhere to the recommended regimen. It is important to take medication as prescribed and not miss any doses or take the drugs intermittently. Failure to do so can lead to disease progression, drug resistance, and treatment failure.

Monitoring: It is crucial to regularly check the viral load and CD4+ T-cell count when receiving antiretroviral medication. This aids in determining the treatment's efficacy and may help with any necessary alterations to the regimen.

Treatment for HIV-1 infection is often lifelong because it is a chronic illness. When antiretroviral medication is effective, it can support HIV-positive people in living long, healthy lives. Atazor R Tablet is an antiretroviral drug belonging to the protease inhibitors category, containing the active ingredients Atazanavir, Ritonavir. It is used in the treatment of HIV-1 infection.

It's crucial to remember that each person has unique needs, which may affect the selection of specific HIV Medication and treatment plans. Potential side effects, drug interactions, comorbidities, and patient preferences are just a few of the variables considered throughout the selection process. Antiretroviral therapy should be chosen and administered under the direction of medical professionals with experience in treating HIV.
