A Review of the Current Status of Antiviral Drugs Targeting Human Immunodeficiency Virus, Hepatitis and Others.

Antiviral drugs are pivotal in the prevention and management of infections caused by viruses, ranging from common cold viruses to life-threatening pathogens like human immunodeficiency virus, hepatitis viruses, Ebola virus, etc. Furthermore, antiviral therapy is increasingly being integrated into the management of chronic viral infections to restrain their replication, avert disease progression, and minimize the risk of complications. The availability of newer generations of antiviral drugs, particularly direct-acting antivirals, and combination therapies have significantly improved treatment outcomes, offering better cure speed, shorter treatment time, and reduced side effects as compared to older-generation antivirals. This comprehensive review provides an in-depth analysis of the diverse classes of antiviral drugs, their mechanisms of action, clinical applications, challenges, and future directions. With a focus on recent advancements and emerging trends, the current landscape of antiviral drug development and its implications for global public health are also discussed.
