Saquinavir

Introduction

Saquinavir is an antiretroviral medicine used in the treatment of Human Immunodeficiency Virus (HIV) infection. It belongs to the class of drugs known as protease inhibitors, which help control the multiplication of the virus in the body. Saquinavir is usually taken in combination with other antiretroviral drugs as part of Highly Active Antiretroviral Therapy (HAART). Although it is not a cure for HIV, it significantly reduces viral load, strengthens the immune system, and lowers the risk of HIV-related complications.

Uses of Saquinavir

• Management of HIV-1 infection
• Reduces viral load in the blood
• Improves immune function in HIV-positive individuals
• Used as part of combination antiretroviral therapy (HAART)

How Saquinavir works

Saquinavir works by inhibiting the activity of HIV protease, an enzyme required by the virus to replicate and produce infectious particles. By blocking this enzyme, Saquinavir prevents the virus from multiplying, thereby reducing the overall viral load in the body and improving immune function.

Benefits of Saquinavir

• Reduces progression of HIV infection
• Improves quality of life for HIV patients
• Delays the onset of AIDS
• Helps in maintaining a stronger immune system
• Effective when used in combination with other antiretrovirals
