Pharmacokinetics
Chloroquine phosphate demonstrates complex pharmacokinetics. After oral administration, it is absorbed quickly but incompletely from the gastrointestinal tract. Once absorbed, it achieves peak plasma concentrations within a few hours. The drug displays a large volume of distribution, indicative of extensive tissue binding. Chloroquine 250 mg binds to various organs, including the liver, spleen, kidneys, and lungs. This property contributes to its efficacy in treating diseases with systemic involvement. The drug undergoes hepatic metabolism, mainly through dealkylation processes. Its metabolites retain pharmacological activity. Excretion occurs primarily via the kidneys, with a small percentage excreted in unchanged form.
Usage Guidelines for Generic Chloroquine
Generic Chloroquine 500 mg requires careful administration. It’s essential to take it with food or a glass of milk to minimize gastrointestinal discomfort. Adherence to the prescribed dosage regimen optimizes therapeutic outcomes. Patients should swallow tablets whole without crushing or chewing. Taking doses at the same time each day helps maintain consistent drug levels in the body.
Eligibility for Generic Chloroquine
Eligible individuals include those with a prescription for malaria prophylaxis or autoimmune conditions such as rheumatoid arthritis and lupus.

Missed Dose Protocol
If a dose of Generic Chloroquine 500 mg is missed, it should be taken as soon as remembered unless it is close to the next scheduled dose.
