Mechanism & Pharmacology

Chloroquine functions primarily by interfering with the growth of malaria parasites, specifically targeting the parasites that invade red blood cells. Knowing how it works helps patients understand its efficacy in treating malaria and other conditions.

Simplified explanation

In straightforward terms, chloroquine works by entering the malaria parasite and disrupting its ability to digest haemoglobin. This process starves the parasite, ultimately leading to its death. By halting the parasite’s development, chloroquine effectively alleviates the symptoms of malaria and prevents the disease from worsening.

Clinical terms

From a clinical perspective, chloroquine exhibits pharmacokinetic properties characterized by good oral bioavailability, with a long half-life that supports once-daily dosing. It undergoes hepatic metabolism and is primarily excreted in urine. The pharmacodynamics show that chloroquine exhibits dose-dependent effects against various Plasmodium species, enhancing its utility in treating both acute and resistant malaria forms. It’s additionally effective against certain autoimmune conditions due to its immunomodulatory activities.
