    General antimicrobial mechanism of action of chloroquine. Chloroquine accumulates in very high concentrations in the parasite food vacuole Geary et al. 1986. Once in the food vacuole, chloroquine is thought to inhibit the detoxification of heme. Chloroquine becomes protonated to CQ 2+ because the digestive vacuole is acidic pH 4.7 In this video, I will explain into one of the main antimalarial drug, chloroquine. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive. An important mode of action of chloroquine and hydroxychloroquine is the interference of lysosomal activity and autophagy.

    For all uses of chloroquine: WARNING/CAUTION: Even though it may be rare, some people may have very bad and sometimes deadly side effects when taking a drug. Do not start, stop, or change the dose of any drug without checking with your doctor.

    What is the mechanism of action of chloroquine? Chloroquine concentrates in parasite food vacuoles and prevents parasitic detoxification of heme to non-toxic hemozoin. This causes lysis of both the parasite and the RBC. Chloroquine has a negative inotropic action, inhibits spontaneous diastolic depolarization, slows conduction, lengthens the effective refractory period and raises the electrical threshold. This results in depression of contractility, impairment of conductivity, decrease of excitability, but with possible abnormal stimulus re-entry mechanism. Mechanism of Action Chloroquine is an antimalarial agent. While the drug can inhibit certain enzymes, its effect is believed to result, at least in part, from its interaction with DNA.

    The CDC recommends taking Lariam for anti-malaria - New Delhi. Answer 1 of 8 I'd like to know if this is commonly used by travelers. I read the side-effects and they look severe. Maybe the side-effects are exagerated, but I'd appreciate anyone's experience with this.
