Anti-Viral Drugs by Andrew M Bambala - 3rd Year Pharmacology and Toxicology - Biomedical Sciences School of Health Sciences-unza

Description

These comprehensive tertiary-level notes on Anti-Viral Drugs are authored by Andrew M Bambala for a third-year Pharmacology and Toxicology programme within the Biomedical Sciences School of Health Sciences. The document begins by explaining the structure of viruses as obligate intracellular parasites and classifying DNA and RNA viruses, including retroviruses like HIV. It details the viral replication cycle and identifies key targets for antiviral drugs. The material systematically covers the treatment of respiratory viral infections, focusing on neuraminidase inhibitors (Oseltamivir, Zanamivir) and M2 ion channel blockers (Amantadine, Rimantadine) for influenza, including their mechanisms, pharmacokinetics, and adverse effects. A significant section addresses the treatment of hepatic viral infections, detailing drugs for Hepatitis B and C, such as Interferon, Lamivudine, and combination therapies. The notes extensively cover anti-herpes drugs, with a focus on Acyclovir and Foscarnet, explaining their mechanisms and clinical uses. A major portion is dedicated to the treatment of HIV infection, outlining the goals of Highly Active Antiretroviral Therapy (HAART) and the six main drug classes: Nucleoside/Nucleotide Reverse Transcriptase Inhibitors (NRTIs), Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs), Protease Inhibitors, Entry/Fusion inhibitors, Integrase inhibitors, and CCR5 antagonists, along with principles of combination regimens. The document also includes a substantial section on COVID-19, discussing potential treatments like monoclonal antibodies (e.g., Baricitinib, Tocilizumab), antivirals (e.g., Remdesivir), and the rationale for vaccines. It concludes with a detailed overview of vaccine development, explaining different vaccine technologies (attenuated, inactivated, subunit, viral vector, nucleic acid) and the accelerated development process for COVID-19 vaccines, listing several approved examples. This resource is an essential study aid for university students in biomedical and health sciences, providing crucial revision material for understanding antiviral pharmacotherapy and immunisation strategies.
