Protease inhibitor (pharmacology)

Protease Inhibitor (Pharmacology)

A protease inhibitor is a type of medication used primarily to treat viral infections. These drugs work by blocking the activity of protease enzymes, which are necessary for the replication of certain viruses, including HIV and Hepatitis C.

Mechanism of Action

Protease inhibitors work by binding to the active site of the protease enzyme, preventing it from cleaving protein precursors into functional viral proteins. This inhibits the ability of the virus to replicate and infect new cells.

Types of Protease Inhibitors

There are several types of protease inhibitors, each designed to treat specific viral infections:

• HIV protease inhibitors: These are used in the treatment of HIV and AIDS. Examples include Ritonavir, Indinavir, and Darunavir.
• Hepatitis C protease inhibitors: These are used to treat Hepatitis C. Examples include Boceprevir, Telaprevir, and Simeprevir.

Side Effects

Like all medications, protease inhibitors can cause side effects. Common side effects include nausea, diarrhea, and rash. In some cases, these drugs can also cause serious side effects like liver damage and diabetes.

Drug Interactions

Protease inhibitors can interact with other medications, including other antiviral drugs, antibiotics, and antifungal drugs. It's important for patients to inform their healthcare provider of all medications they are currently taking.
