Pharmacokinetics
The pharmacokinetics of Chloroquine 500 mg showcases its journey in the body. After oral intake, absorption occurs in the gastrointestinal tract. Peak plasma concentrations emerge within one to two hours. The drug’s extensive distribution results in high tissue concentrations, particularly in the liver, spleen, and kidneys. Chloroquine is extensively bound to proteins and tissues, and its volume of distribution is substantial.
Chloroquine undergoes biotransformation in the liver. The process generates an active metabolite, desethylchloroquine. Both compounds contribute to the pharmacological effects. Elimination occurs via the kidneys, with a half-life ranging between one to two months. Renal impairment necessitates dosing adjustments, as the drug’s clearance rate declines.
Mechanism of Action
Chloroquine phosphate 250 mg exerts its therapeutic action by inhibiting parasite growth in red blood cells. It interferes with the digestion of hemoglobin by Plasmodium species. Accumulation of toxic by-products leads to parasite death. Its role in autoimmune diseases involves modulation of immune responses. Chloroquine reduces cytokine production, which alleviates inflammation.
In malaria, chloroquine is most effective against erythrocytic forms of Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae. Resistance is widespread in Plasmodium falciparum. The anti-inflammatory action benefits conditions like rheumatoid arthritis and lupus erythematosus. These actions, both antimalarial and anti-inflammatory, contribute to its versatility in therapeutic applications.

This medication is contraindicated in those with retinal or visual field changes. Caution applies to individuals with liver or kidney disease, psoriasis, or porphyria.
A detailed medical history ensures safety and efficacy. Those with known hypersensitivity to chloroquine or related compounds must avoid this medication. Health care providers evaluate risk factors, weighing benefits against potential harm. Additional guidance from trusted medical sources aids in decision-making.
