A potent and specific HIV protease inhibitor that appears to have good oral bioavailability. [PubChem]

Indivex is a protease inhibitor with activity against Human Immunodeficiency Virus Type 1 (HIV-1). Protease inhibitors block the part of HIV called protease. HIV-1 protease is an enzyme required for the proteolytic cleavage of the viral polyprotein precursors into the individual functional proteins found in infectious HIV-1. Indivex binds to the protease active site and inhibits the activity of the enzyme. This inhibition prevents cleavage of the viral polyproteins resulting in the formation of immature non-infectious viral particles. Protease inhibitors are almost always used in combination with at least two other anti-HIV drugs.

Uses

Indivex is a protease inhibitor used to treat HIV infection.

Indivex is an antiretroviral drug for the treatment of HIV infection.

Indivex is also used to associated treatment for these conditions: Human Immunodeficiency Virus Type 1 (HIV-1) Infection

How Indivex works

Indivex inhibits the HIV viral protease enzyme which prevents cleavage of the gag-pol polyprotein, resulting in noninfectious, immature viral particles.

Toxicity

Symptoms of overdose include myocardial infarction and angina pectoris.

Food Interaction

  • Avoid excessive or chronic alcohol consumption.
  • Avoid grapefruit products.
  • Take on an empty stomach. Take at least 1 hour before or 2 hours after meals.
  • Take with a full glass of water.

[Moderate] ADJUST DOSING INTERVAL: According to the manufacturer, coadministration with a meal high in calories, fat, and protein reduces the absorption of indinavir.

In ten patients given indinavir in this manner, the peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of indinavir decreased by an average of 84% and 77%, respectively.

In contrast, grapefruit juice may have only minor effects on the oral bioavailability of indinavir.

The manufacturer's package labeling states that administration of a single 400 mg dose of indinavir with 8 oz. of grapefruit juice decreased indinavir AUC by an average of 26%.

Likewise, a study consisting of 14 HIV-infected subjects found no uniform nor significant changes in steady-state indinavir AUC during administration with double-strength grapefruit juice compared to water.

There was, however, a delay in absorption (Tmax) due to grapefruit juice that is unlikely to be of clinical significance.

MANAGEMENT: To ensure maximal oral absorption, indinavir should be administered without food but with water 1 hour before or 2 hours after a meal.

Alternatively, indinavir may be administered with other liquids such as skim milk, juice, coffee, or tea, or with a light meal (e.g., dry toast with jelly, juice, and coffee with skim milk and sugar; corn flakes, skim milk and sugar).

Indivex Cholesterol interaction

[Moderate] Hyperlipidemia has been observed in 10% of patients receiving ritonavir during clinical trials.

Increases of 30% to 40% from baseline have been reported for total cholesterol and 200% to 300% or more for triglycerides.

These effects have also been reported during postmarketing experience with other protease inhibitors (PIs) but may be the most dramatic with ritonavir.

The clinical significance of these elevations is unclear.

Severe hyperlipidemia is known to sometimes cause pancreatitis.

In addition, some patients have reportedly developed symptomatic atherosclerosis and coronary artery disease after initiating PI treatment.

Patients with preexisting hyperlipidemia may require closer monitoring during PI therapy, and adjustments made accordingly in their lipid-lowering regimen.

PI therapy should be administered cautiously in patients with coronary artery disease or a history of ischemic heart disease.

Elimination Route

Rapidly absorbed

Half Life

1.8 (± 0.4) hours

Elimination Route

Less than 20% of indinavir is excreted unchanged in the urine.
