PROTEASE INHIBITORS Meaning and
Definition
-
Protease inhibitors are a class of drugs primarily used in the treatment of viral infections, such as HIV and hepatitis C. Their mechanism of action involves inhibiting the activity of enzymes called proteases, which play a crucial role in the replication and assembly of viruses within host cells.
Proteases are enzymes that break down proteins by cutting them into smaller fragments. In the context of viral infections, proteases are responsible for cleaving viral polyproteins into individual functional proteins necessary for viral replication and maturation. By inhibiting protease activity, protease inhibitors prevent the formation of these vital viral proteins, thus effectively halting the replication and spread of the virus.
In the case of HIV, protease inhibitors are often used in combination with other antiretroviral drugs as part of highly active antiretroviral therapy (HAART). HAART helps suppress the virus to undetectable levels in the blood, thereby reducing the progression of HIV infection to AIDS and improving the overall immune function of individuals living with HIV.
Protease inhibitors have also demonstrated efficacy in treating hepatitis C, another viral infection that affects the liver. By impairing the protease activity of the hepatitis C virus, these drugs hinder viral replication and assist in preventing the progression of chronic hepatitis C infection to cirrhosis, liver failure, or hepatocellular carcinoma.
While protease inhibitors have proven to be important therapeutic agents in the management of certain viral infections, they are not without side effects. Common side effects include gastrointestinal discomfort, metabolic abnormalities, liver toxicity, and the potential for drug-drug interactions. Regular monitoring and strict adherence to prescribed doses are essential to ensure optimal therapeutic outcomes while minimizing adverse effects.

Etymology of PROTEASE INHIBITORS
The term "protease inhibitors" can be broken down into two parts: "protease" and "inhibitors".
1. Protease:
The word "protease" is derived from the Greek word "proteos", which means "of the first quality" or "primary". It is combined with the suffix "-ase", which is used to denote an enzyme. Therefore, "protease" refers to an enzyme that breaks down proteins by hydrolyzing peptide bonds.
2. Inhibitors:
The term "inhibitors" comes from the Latin word "inhibere", meaning "to restrain". In the context of enzymes, an inhibitor is a substance that binds to an enzyme and reduces or stops its activity.
When combined, "protease inhibitors" specifically refer to substances or drugs that inhibit the action of protease enzymes, thereby preventing the breakdown of proteins.
