Safely Buy Prezista ( Darunavir ) from Canada Prescriptions Plus.

Indications

Prezista is an antiviral medication used to treat HIV and prevent it from developing into AIDS.

Darunavir is a protease inhibitor that prevents the replication and growth of mature virus particles by inhibiting specific protease enzymes and polyproteins responsible for HIV spread. The drug has also been found to be effective against HIV strains that are resistant to older forms of treatment. These inhibitory actions allow Prezista to manage and treat HIV in a range of patients.

This antiviral medication is a safe and effective form of treatment for HIV in patients with treatment resistant strains, who have had previous treatment, or who have yet to be treated. Prezista is generally well-tolerated, the most common side effects being gastrointestinal and lipid abnormalities. When administered once daily, these effects are similar to other treatments and provide effective management of viral activity.
