To treat PCP effectively, it is usually combined with clindamycin. However, the exact mechanism of action is not fully understood. Plaquenil and tums Inj chloroquine dose Chloroquine and quinine have gametocytocidal activity against P. vivax and P. malariae, but not against P. falciparum. Primaquine has gametocytocidal activity against all plasmodia, including P. falciparum. Sporontocides These drugs prevent the development of oocysts in the mosquito and thus ablate the transmission. Primaquine and chloroguanide have this action. Chloroquine is the ONLY drug used for P. vivax malaria, because resistance to chloroquine in P. vivax malaria is almost unknown in most countries.

Administration of primaquine with food or grapefruit juice increases its oral bioavailibity. However, the WHO has recommended that a single dose of primaquine (0.25 mg/kg) is safe to give even in individuals with G6PD deficiency, for the purpose of preventing transmission of P. Primaquine overdose can cause a dangerous reduction in various blood cell counts, and therefore should be avoided in people at risk for agranulocytosis, which include people with conditions such as rheumatoid arthritis and lupus erythematosus, and those taking concurrent medications that also decrease blood cell counts.

The assays were performed in triplicate on at least 2 separate occasions Chloroquine 25 mg/kg over 3 days with a single dose of SP as described above. SP plus amodiaquine This combination has been shown to produce a faster rate of clinical recovery than SP and chloroquine, but is clearly inferior to artemisinin-based combinations ACTs for the treatment of malaria.
