Indinavir

Introduction: What is Indinavir?

Indinavir is an antiretroviral medication primarily used in the treatment of HIV (Human Immunodeficiency Virus) infection. It belongs to a class of drugs known as protease inhibitors, which work by blocking the action of the protease enzyme that HIV needs to replicate. By inhibiting this enzyme, Indinavir helps to reduce the viral load in the body, allowing the immune system to recover and function more effectively.

Uses of Indinavir

Indinavir is approved for the treatment of HIV1 infection in combination with other antiretroviral agents. It is not a cure for HIV but is effective in managing the virus, helping to prevent the progression to AIDS (Acquired Immunodeficiency Syndrome). Indinavir is typically prescribed for adults and children over the age of 2 who are HIVpositive.

Jak to funguje

Indinavir works by inhibiting the protease enzyme, which is crucial for the HIV virus to mature and replicate. In simpler terms, think of the protease enzyme as a pair of scissors that cuts up the viral proteins needed for the virus to assemble and become infectious. By blocking this enzyme, Indinavir prevents the virus from producing new copies of itself, thereby reducing the amount of virus in the bloodstream.

Dávkování a správa

The standard dosage of Indinavir for adults is typically 800 mg taken every 8 hours. For children aged 2 years and older, the dosage is based on body weight and should be determined by a healthcare provider. Indinavir is available in capsule form and should be taken on an empty stomach, ideally one hour before or two hours after a meal. It is important to drink plenty of water while taking Indinavir to prevent kidney stones, a common side effect.
