Speaker
notes: A number of PIs fall to concentrations which are
undesirably close to levels where the virus is not fully inhibited:
- because
of inter-individual variability, some individuals may have drug
levels below this mark
- e.g. indinavir
(IDV) administered at 800mg TID.
Adding ritonavir
(RTV) at 400mg BID with food to IDV 400mg BID shows:
- prolonged
IDV half life (t½)
- reduced
IDV Cmax
- overall,
the IDV Cmin is increased way above the IC95.
