Ja. Bilello et al., IMPACT OF DOSING SCHEDULE UPON SUPPRESSION OF A RETROVIRUS IN A MURINE MODEL OF AIDS ENCEPHALOPATHY, Antimicrobial agents and chemotherapy, 38(3), 1994, pp. 628-631
We studied the impact of zidovudine (AZT) in Cas-Br-M murine leukemia
virus-infected NFS-N mice after administration by once-daily bolus or
continuous infusion. While higher peak concentrations of AZT were achi
eved by once-daily dosing, continuous AZT infusion at 25 mu g/h mainta
ined levels >1 mu M in plasma and >0.2 mu M in the brain. Continuous i
nfusion provided significantly better viral inhibition, even though to
tal doses were only one-third that of the once-daily therapy group.
