Trial summary

To determine if zidovudine (AZT) and acetaminophen (APAP) interact when given to the same patient, and if so, the manner of interaction. Patients with AIDS often require therapy with painkillers for the management of mild pain and discomfort associated with their disease, and APAP is often prescribed. Read more about this study

About this study

To determine if zidovudine (AZT) and acetaminophen (APAP) interact when given to the same patient, and if so, the manner of interaction. Patients with AIDS often require therapy with painkillers for the management of mild pain and discomfort associated with their disease, and APAP is often prescribed. AZT is being used to treat AIDS patients. It is important for doctors to understand how AZT and APAP may interact when given to the same patient, because other studies have suggested that the dosage of AZT may have to be adjusted when given with APAP in order to avoid or minimize adverse effects.

Patients with AIDS often require therapy with painkillers for the management of mild pain and discomfort associated with their disease, and APAP is often prescribed. AZT is being used to treat AIDS patients. It is important for doctors to understand how AZT and APAP may interact when given to the same patient, because other studies have suggested that the dosage of AZT may have to be adjusted when given with APAP in order to avoid or minimize adverse effects.

Persons who are infected with HIV and have symptoms (fever, fatigue, weight loss) of AIDS are eligible for the study. They will be given AZT orally every 4 hours or APAP orally every 8 hours alone or in combination for 4 days while at home. On the 4th day, participants will be admitted to a clinical research center for studies to determine how they are tolerating the medicine. On the 5th day, any scheduled 8 am doses of AZT will be given intravenously, while the scheduled doses of APAP will still be given orally. Repeated blood samples will be taken over the next 12 hours and urine will be collected for 24 hours. The process will be repeated at weekly intervals for 3 weeks, so that each patient receives AZT alone, APAP alone, and the combination of AZT and APAP.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00000731, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2021.
