How does Zidovudine work in the body?
Zidovudine works by inhibiting the reverse transcriptase enzyme, which is crucial for the replication of HIV. By blocking this enzyme, Zidovudine prevents the virus from multiplying and spreading throughout the body. This action helps in maintaining a lower viral load and allows the immune system to recover and function more effectively. The drug is incorporated into the viral DNA chain, causing premature termination of the viral DNA synthesis.
In what forms is Zidovudine available?
Zidovudine is available in several dosage forms to accommodate different patient needs. These include oral tablets, capsules, and an oral solution. The tablets and capsules are typically available in strengths of 100 mg and 300 mg, while the oral solution is available in a concentration of 50 mg per 5 mL. This variety allows for flexible dosing schedules and ease of administration, particularly for pediatric or elderly patients who may have difficulty swallowing pills.

When was Zidovudine first developed and approved by the FDA?
Zidovudine was first developed in the 1960s as a potential treatment for cancer, but it was not until the 1980s that its efficacy against HIV was discovered. The U.S. Food and Drug Administration (FDA) approved Zidovudine for the treatment of HIV infection in 1987, making it the first antiretroviral drug available for this purpose. Since then, Zidovudine has played a significant role in the management of HIV and has paved the way for the development of other antiretroviral medications.
