Mechanism of action of chloroquine. Entry into the parasitized RBCs; 1. Accumulation in food vacuole of the parasite- role of pH gradient chloroquine trapping Affects asexual cycle of plasmodium specie. Once administered, it has to enter site of action. It rapidly enters and gets concentrated in food vacuole, present within erythrocytes. Two mechanisms are thought to be involved in chloroquine accumulation into the P. falciparum vacuole acidic trapping due to low vacuolar pH and chloroquine binding to heme or heme related species. It is reasonable to assume that PfCRT does not directly affect the molecular mechanism of chloroquine-HM binding. The most serious adverse effects affect the eye, with dose-related retinopathy as a concern even after hydroxychloroquine use is discontinued.

Presenter Dr. Tanmay Mehta MD, DNB, PGDCTM The drug chloroquine is bactericidal for Bacillus megaterium ; it inhibits DNA and RNA biosynthesis and produces rapid degradation of ribosomes and dissimilation of ribosomal RNA. Inhibition of protein synthesis is also observed, evidently as a secondary effect. Inhibition of DNA replication is proposed as a general mechanism of the antimicrobial action of chloroquine. A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen.
