How does Atavir 300 mg Capsule work?
Inhibiting the Protease Enzyme
The activation process involves the use of a unique set of enzymes, which cut the long chain of proteins into smaller functional segments that constitute an active HIV particle.
Disabling the Machinery
One of the active components of the drug Atavir 300 mg (atazanavir) latches onto the protease enzyme, effectively binding it.
Producing Defective, Immature Viruses
Because of such bonding, the enzyme is disabled from splitting the proteins. In this way, the newly generated virus becomes defective and immature. These immature particles do not contain any capability of infecting other cells.

What are the benefits of taking Atavir 300 Capsule
Strong Viral Suppression
The key advantage of using Atavir is that the medication helps reduce the level of HIV in the blood to undetectable levels. For most patients, regular consumption helps keep the viral load at undetectable levels.
Causes No Disease Progression
As the medication keeps the virus in check, Atavir ensures that HIV does not harm organs and reach its more severe stages, including AIDS.
Principle of U=U
Once the patient attains and maintains an undetectable viral load, it becomes impossible for the patient to pass on HIV infection to other people through unprotected sex.
Increases CD4 Cells
The reason why Atavir can effectively prevent the infection from targeting and destroying your immune defence cells is that the CD4 T-cell count in your body rises significantly.
Prevention of Opportunistic Infections
Due to your immune system becoming very strong once it has been restored, you will be in a better position to protect yourself against illnesses such as pneumonia and meningitis.
Safe for Blood Lipids
Unlike other antiretroviral medicines, Atavir 300 mg Capsule is less likely to result in an increase in cholesterol and triglycerides in the blood.
Less Risk of Lipodystrophy
It poses less risk of lipodystrophy, which is characterised by abnormal shifting of body fat from one part of the body to another, and was among the many issues presented by earlier HIV treatments.
Once-a-Day Regimen
Due to its long half-life (more so after boosting), Atavius is administered just once daily. Such an easy regimen makes it very convenient for adherence.
