It has remained the only FDA licensed drug capable of clearing the intra-hepatic schizonts and hypnozoites of Plasmodium vivax. The fact that systematic, iterative experiments had eventually synthesized an antimalarial drug that was 30 times more effective than quinine[2]:91 while being safe enough to use (relative to the bleak alternatives of the era) supported the concept of modern pharmaceutical research laboratories as it would develop in coming decades. The risk of relapse of Plasmodium vivax malaria without primaquine therapy ranged from 5% to 80% or more . ~III B.

[16][17], Common side effects of primaquine administration include nausea, vomiting, and stomach cramps. Synthesized as a part of extensive cooperative programme of antimalarial research in US during world war2 . although these drugs are known to accumulate by a weak base mechanism in the acidic food vacuoles of intraerythrocytic trophozoites and thereby prevent hemoglobin degradation from occurring in that organelle, the mechanism by which their selective toxicity for lysosomes of malaria trophozoites is achieved has been subject to much discussion and 1,2,8,9 Primaquine combined with clindamycin is also effective in the treatment of P. jirovecii pneumonia. It also collects in red blood cells similar to Artenimol. In contrast, a report has shown that nitrofurazone is also able to destroy T. cruzi through trypanothione reductase inhibition, this enzyme is found in the parasite but not in the host.
