Hydroxychloroquine sulfate is indicated for the prophylaxis of malaria in geographic areas where chloroquine resistance is not reported. Limitations of Use in Malaria • Hydroxychloroquine sulfate is not recommended for the treatment of complicated malaria. • Hydroxychloroquine sulfate is not effective against chloroquine or hydroxychloroquine-resistant strains of Plasmodium species (see CLINICAL PHARMACOLOGY – Microbiology). Hydroxychloroquine sulfate is not recommended for the treatment of malaria acquired in geographic areas where chloroquine resistance occurs or when the Plasmodium species has not been identified. • Hydroxychloroquine sulfate is not recommended for malaria prophylaxis in geographic areas where chloroquine resistance occurs. • Hydroxychloroquine sulfate does not prevent relapses of P. vivax or P. ovale because it is not active against th

CLINICAL PHARMACOLOGY
PHARMACOKINETICS
Following a single 200 mg oral dose of hydroxychloroquine sulfate to
healthy males, the
mean peak blood concentration of hydroxychloroquine was 129.6 ng/mL,
reached in
3.26 hours with a half-life of 537 hours (22.4 days). In the same
study, the plasma peak
concentration was 50.3 ng/mL reached in 3.74 hours with a half-life of
2963 hours
(123.5 days). Urine hydroxychloroquine levels were still detectable
after 3 months with
approximately 10% of the dose excreted as the parent drug. Results
following a single
dose of a 200 mg tablet versus i.v. infusion (155 mg), demonstrated a
half-life of about
40 days and a large volume of distribution. Peak blood concentrations
of metabolites
were observed at the same time as peak levels of hydroxychloroquine.
The mean
fraction of the dose absorbed was 0.74. After administration of single
155 mg and 310
mg intravenous doses, peak blood concentrations ranged from 1161 ng/mL
to 2436
ng/mL (mean 1918 ng/mL) following the 155 mg infusion and 6 months
following the
310 mg infusion. Pharmacokinetic parameters were not significantly
different over the
therapeutic dose range of 155 mg and 310 mg indicating linear
kinetics.
Following chronic oral administration of hydroxychloroquine,
significant levels of
