Antiretroviral Drugs - GCSE Biology Definition

Antiretroviral drugs are medications used to treat infections caused by retroviruses, most notably the Human Immunodeficiency Virus (HIV) which leads to AIDS. These drugs work by inhibiting the replication of the virus within the body, helping to reduce the viral load to undetectable levels and allowing the immune system to recover and function effectively. Antiretroviral therapy (ART) typically involves a combination of different drugs to prevent the virus from developing resistance. While not a cure for HIV, when taken consistently, these drugs can significantly prolong and improve the quality of life for those living with the virus. Understanding how these drugs operate and their importance in controlling viral infections is crucial for students studying their effects on the human body and disease management in GCSE Biology.
