Agaba Tablets: Uses, Dosage, Side Effects and Composition

Description and Composition of Agaba

Agaba is an antimalarial combination drug that contains Artemisinin and Piperaquine as its active pharmaceutical ingredients. It is a tablet coated with green film. Agaba is a fixed dose Artemisinin based Combination Therapy (ACT), and each tablet contains artemisinin 62.5 mg and piperaquine 375 mg.

Pharmacology and Toxicology of Agaba

Agaba is a drug used for the treatment of malaria, particularly drug-resistant falciparum malaria. It Is well tolerated and has rapid action, high efficacy, low toxicity and offers a short course treatment. Using artequick to treat falciparum malaria with 56-day follow-up, the results showed that the cure rate was >95%, the fever and parasite clearance time were 16-30 and 36-60 hours respectively. Agaba also has parasiticidal effect on plasmodium vivax in intraerythrocyte stage.

Artemisinin in Agaba tablets has powerful and quick parasiticidal effect on those parasites in intraerythrocyte stage. Moreover, its efficacy is much quicker than that of quinine, chloroquine and all other nonartemisinin antimalarial drugs. It therefore relieves clinical symptoms much faster. This product has significant gametocidal effects on falciparum malaria thus interrupts the generation of gametocytes in bone marrow and reduces the transmission.

The resistance culture showed that the drug resistance to this product is hard to occur. Piperaquine is a 4-aminoquinolone compound. Studies of the pharmacodynamic and toxicological properties in rodent malaria showed that the efficacy and curative index of piperaquine were 2.6 and 6.6 times higher than those of chloroquine. Since 1978, piperaquine has been used widely to replace chloroquine to treat malaria in China and proven its higher therapeutic efficacy and fewer side effects than those of chloroquine.

The results of acute toxicity tests in mice given the drug by intragastric administration showed that LDs of the product was 1053.5 mg/kg, and the toxicity of the combination of the two components was not potentiated but additive.

Genetic toxicology tests showed that the product has no mutagenic effects. It was showed that artemisinin, one component of the product hasfetus toxicity in the 9-14 day pregnant mice, mainly represented as absorptive fetus.

Taking this product consecutively with high dose would induce slight injury of the liver function and decrease of reticulocyte count, but this change is reversible, and it can recover quickly after quitting the drug
