Indinavir – What It Is and Why It Matters in HIV Care

When exploring Indinavir, a protease inhibitor used to fight HIV infection. Also known as Crixivan, it belongs to the class of drugs that target the viral enzyme protease, stopping the virus from maturing. Human Immunodeficiency Virus (HIV) is the virus that attacks the immune system, and controlling it requires a antiretroviral therapy (ART) regimen that often includes several drug classes. One of the core principles of ART is combining a protease inhibitor like Indinavir with other agents to lower the viral load and prevent drug resistance. This first paragraph sets the stage: Indinavir is a key piece of a larger treatment puzzle.

How Indinavir Fits Into the HIV Treatment Landscape

Indinavir’s main attribute is its ability to block the HIV protease enzyme, which is essential for cutting viral polyproteins into functional pieces. By inhibiting this step, the drug forces the virus to release immature, non‑infectious particles. The typical dosage for adults ranges from 800 mg to 1,600 mg taken twice daily, and food timing matters because a high‑fat meal can increase absorption and raise the risk of kidney stones. Side effects often include nausea, fatigue, and metabolic changes such as increased cholesterol, but most patients tolerate the drug well when monitored. In practice, clinicians measure success by the drop in viral load—often from millions of copies per milliliter down to undetectable levels—while watching CD4 cell counts rise, indicating immune recovery. Moreover, Indinavir’s effectiveness can be influenced by genetic factors like CYP3A4 enzyme activity, which determines how quickly the body processes the medication. Understanding these attributes helps doctors tailor regimens, avoid drug‑drug interactions, and plan for long‑term management.

Beyond the chemistry, Indinavir interacts with broader concepts: Indinavir is part of a combination strategy that aims to keep the virus suppressed, reduce transmission risk, and improve quality of life. Researchers continue to compare newer protease inhibitors with Indinavir to assess cost, resistance patterns, and side‑effect profiles. For patients, the practical takeaways include adhering to dosing schedules, staying hydrated to lessen kidney‑stone risk, and keeping regular lab appointments to track viral load and kidney function.
