Antivirals are a class of medications used to treat viral infections by inhibiting the ability of viruses to replicate within the body. These drugs work by targeting specific components of the virus, such as enzymes or proteins, to prevent their ability to reproduce and spread. Antivirals are used to treat a wide range of viral infections, including influenza, HIV, herpes, hepatitis, and more. They can be taken orally, topically, or intravenously depending on the specific virus being treated. Research in the field of antivirals is focused on developing new drugs with improved efficacy, reduced side effects, and broader spectrum of activity against different types of viruses. Additionally, researchers are also investigating new strategies to combat emerging viral strains and drug-resistant viruses.
