Among 49 patients with falciparum malaria, we found neither parasites carrying haplotypes associated with chloroquine resistance nor instances of chloroquine treatment failure Verapamil, a calcium channel blocker, completely reversed chloroquine resistance in two chloroquine-resistant P. They then spread through South and Southeast Asia and by the 1970s were being seen in sub. falciparum. falciparum chloroquine resistance transporter (pfcrt) gene and modified by other mutations in this gene and in the P. Apart from its well-known antimalarial effects, the drug has interesting biochemical properties that might be applied against some viral infections.
