Chloroquine Phosphate Injection 322.5MG/5ML

Indications:

ARALEN is indicated for the suppressive treatment and for acute attacks of malaria due to P. vivax, P.malariae, P. ovale, and susceptible strains of P. falciparum. The drug is also indicated for the treatment of extraintestinal amebiasis.

ARALEN does not prevent relapses in patients with vivax or malariae malaria because it is not effective against exoerythrocytic forms of the parasite, nor will it prevent vivax or malariae infection when administered as a prophylactic. It is highly effective as a suppressive agent in patients with vivax or malariae malaria, in terminating acute attacks, and significantly lengthening the interval between treatment and relapse. In patients with falciparum malaria it abolishes the acute attack and effects complete cure of the infection, unless due to a resistant strain of P. falciparum.

Dosage and administration：

Cerebral malaria patients:

Intravenous infusion 18-24 mg/kg(60kg for those weighing more than 60kg) on day 1, 12mg/kg on day 2, and 10mg/kg on day 3.

The concentration of chloroquine phosphate was added to 10% glucose solution or 5% glucose sodium chloride injection 500ml every 0.5g, and the intravenous infusion rate was 12 to 20 drops per minute.

Contraindications:
