    Why chloroquine is given in loading dose


    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    Where complete treatment of severe malaria is not possible but injections are available, give adults and children a single intramuscular dose of artesunate, and refer to an appropriate facility for further care. Where intramuscular artesunate is not available use intramuscular artemether or, if that is not available, use intramuscular quinine. The study is a double-blind, randomised, placebo-controlled trial that will be conducted in health care settings. After obtaining fully informed consent, the investigator will recruit healthcare workers, or other individuals at significant risk who can be followed reliably for 5 months. 10,000. What I’m wondering is if there is any relationship with increasing the loading dose and the time taken to reach the steady state. For example, if a greater loading dose was given for a particular drug, would this decrease the time taken to reach the steady state compared to smaller loading dose? Thank you very much in advance. Kind Regards, Sarah

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

  7. In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life.

    Chloroquine shouldn’t be utilized in these circumstances except the profit to the affected person outweighs the potential risks. Why chloroquine is given as a loading dose. The key mutation seems to be K76T since no chloroquine resistant isolate carries the wild sort lysine at position 76. Dosage. Chloroquine can be administered either orally or parenterally for treatment of malaria, but prophylaxis is given in tablet form. An effective blood concentration is reached within 2-3 hours if a loading dose of 600 mg base is used. Inappropriate loading dose reduction resulting in ineffectively low plasma concentration is a significant danger in patients with renal impairment. A single loading dose of antibiotic, equivalent to the usual maintenance dose for patients with normal renal function, should almost always be given to patients with impaired renal function.
