Uses

It is used for the prevention and treatment of uncomplicated malaria.

Doses Administration:

It is generally recommended that chemoprophylaxis for travelers should be started about one or two weeks before exposure to malaria, but if this is not possible, it can be started 1 to 2 days prior to travel. The administration should continue throughout exposure and for at least 4 weeks after leaving the malarious area.

Prevention Of Malaria:

Adults: 200 mg [2 tablets daily]

Children: Up to 1 Year: 25 mg [¼ tablet daily] 1 to 4 Years: 50 mg [½ tablet]

5 to 8 Years: 100 mg [1 tablet daily] 9 to 15 Years: 150 mg[1½ tablets daily]

To be taken with or after food. For children, may be crushed and mixed with milk, honey or jam.

Contraindications Warnings:

Should be used with caution in patients with renal impairment; dosage should be reduced accordingly. It is contraindicated in patients with known allergy or any of the excipients used.

Advertised Effects:

Apart from mild gastric intolerance, diarrhea and some reports of aphthous ulceration there appear to be few adverse effects associated with usual doses of Proguanil hydrochloride. Haematological changes may occur in patients with severe renal impairment.

Interactions:

Fluvoxamine can virtually abolish the metabolism of Proguanil to its active metabolite cycloguanil via an inhibitory effect on the cytochrome P450 isoenzyme CYP2C19.

• Each film coated tablet contains: chloroquine phosphate BP 250 mg eq. to chloroquine base 150 mg, excipients Q S, Approved colour used.

• C18H26CIN3.2H3PO4

• 515.87

• Chloroquine phosphate tablets are indicated for 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.

• As directed by the physician.
• The dosage of chloroquine phosphate is often expressed in terms of equivalent chloroquine base. Each 250 mg tablet of chloroquine phosphate is equivalent to 150 mg base.

• Adult Dose: 500 mg (= 300 mg base) on exactly the same day of each week.
• Pediatric Dose: The weekly suppressive dosage is 5 mg calculated as base, per kg of body weight, but should not exceed the adult dose regardless of weight.
• If circumstances permit, suppressive therapy should begin two weeks prior to exposure. The suppressive therapy should be continued for eight weeks after leaving the endemic area.

• Adults: An initial dose of 1 g (= 600 mg base) followed by an additional 500 mg (= 300 mg base) after six to eight hours and a single dose of 500 mg (= 300 mg base) on each of two consecutive days. This represents a total dose of 2.5 g chloroquine phosphate of 1.5 g base in three days.
• The dosage for adults of low body weight and for
infants and children should be determined as follows:
• First dose: 10 mg base/kg (but not exceeding a single dose of 600 mg base).
• Second dose: (6 hours after first dose) 5 mg base/kg (but not exceeding a single dose of 300 mg base).
• Third dose: (24 hours after first dose) 5 mg base/kg.
• Fourth dose: (36 hours after first dose) 5 mg base/kg.
• For radical cure of vivax and malariae malaria concomitant therapy with an 8-aminoquinoline compound is necessary.
