適応症:

Chloroquine phosphate tablets are indicated for the: - Treatment of uncomplicated malaria due to susceptible strains of P. falciparum, P.malariae, P. ovale , and P.vivax. - Prophylaxis of malaria in geographic areas where resistance to chloroquine is not present. - Treatment of extraintestinal amebiasis. Chloroquine phosphate tablets do not prevent relapses in patients with vivax or ovale malaria because it is not effective against exoerythrocytic forms of the parasites. Limitations of Use in Malaria: - Do not use chloroquine phosphate tablets for the treatment of complicated malaria (high-grade parasitemia and/or complications e.g., cerebral malaria or acute renal failure). - Do not use chloroquine phosphate tablets for malaria prophylaxis in areas where chloroquine resistance occurs, Resistance to Chloroquine phosphate tablets is widespread in P. falciparum, and is reported in P.vivax (see WARNINGS). - Concomitant therapy with an 8-aminoquinoline drug is necessary for treatment of the hypnozoite liver stage forms of P.vivax and P.ovale (see DOSAGE AND ADMINISTRATION). Use of chloroquine phosphate tablets for indications other than acute malaria is contraindicated in the presence of retinal or visual field changes of any etiology. Use of chloroquine phosphate tablets is contraindicated in patients with known hypersensitivity to 4-aminoquinoline compounds.

CLINICAL PHARMACOLOGY
Chloroquine is rapidly and almost completely absorbed from the
gastrointestinal tract,
and only a small proportion of the administered dose is found in the
stools.
Approximately 55% of the drug in the plasma is bound to nondiffusible
plasma
constituents. Excretion of chloroquine is quite slow but is increased
by acidification of
the urine. Chloroquine is deposited in the tissues in considerable
amounts. In animals,
from 200 to 700 times the plasma concentration may be found in the
liver, spleen,
kidney, and lung; leukocytes also concentrate the drug. The brain and
spinal cord, in
contrast, contain only 10 to 30 times the amount present in plasma.
Chloroquine undergoes appreciable degradation in the body. The main
metabolite is
desethylchloroquine, which accounts for one fourth of the total
material appearing in the
urine; bisdesethylchloroquine, a carboxylic acid derivative, and other
metabolic products
as yet uncharacterized are found in small amounts. Slightly
