Description

Preliminary studies using human liver tissue have shown that valproic acid inhibits the metabolic inactivation of zidovudine (AZT), which may prolong the plasma half-life of AZT and thus prolong the duration of the drug's effects in the body. Six asymptomatic HIV-infected patients are treated with AZT orally every 8 hours on days 1 through 4, then with a single dose on day 5 (after 8 hours of fasting), followed by pharmacokinetic sampling. On days 6 through 9, patients receive AZT orally every 8 hours in combination with valproic acid (lowest dose in the first 5 patients and a higher dose ...
