Parenteral quinidine has the potential to increase the QT interval and therefore requires electrocardiographic monitoring. But quinine is also a deterrent to malaria–and the malaria treatments are being used for treating Covid 19 patients–Trump himself using one of the medicines. This chapter reviews the drugs (in alphabetical order) used for the prevention and treatment of malaria. Clindamycin, although less effective than doxycycline or atovaquone-proguanil, is used in combination with quinine for those unable to tolerate or who have contraindications to the use of first-line agents (e.g. : WHO; 2015.Carroll ID, Williams DC. Atovaquone-proguanil is effective as a causal (acting at the liver stage) as well as a suppressive (acting at the blood stage) prophylactic agent. 2011.Gonzalez R, Hellgren U, Greenwood B, Menendez C. Mefloquine safety and tolerability in pregnancy: a systematic literature review. This strategy allows the traveller time to contact the prescribing physician to arrange an alternative antimalarial if needed. The metabolism of primaquine to its active metabolite is dependent on CYP 2D6. Malar J 2010 Dec 9;9:357-2875-9-357.Schlagenhauf P. Mefloquine for malaria chemoprophylaxis 1992-1998: a review. In randomized controlled trials of doxycycline at prophylactic doses, nausea and abdominal pain were the most commonly reported mild to moderate adverse eventsDoxycycline has high level efficacy (93%–100%) for the prevention of chloroquine-resistant P. falciparum and for mefloquine-resistant Travellers should be informed about the small doxycycline-associated risks of esophageal ulceration, vaginal candidiasis and photosensitivity.Concurrent use of doxycycline with barbiturates, carbamazapine or phenytoin may result in a 50% decrease in doxycycline serum concentration.People taking minocycline for the treatment of acne or rheumatoid arthritis should switch to doxycycline 100 mg daily for the duration of their stay in the malaria-endemic area plus for four weeks after leaving the area, then switch back to their usual dose of minocycline.Mefloquine is a fluorinated quinoline. COVID-19 is an emerging, rapidly evolving situation. phosphate (equivalent to 155 mg of chloroquine base).

Note that the preponderance of literature on efficacy of tetracyclines as antimalarials has focused on doxycyclineDoxycycline can cause gastrointestinal upset and, rarely, esophageal ulceration or esophagitis.

Tolerability of malaria chemoprophylaxis in non-immune travellers to sub-Saharan Africa: multicentre, randomised, double blind, four arm study. 2013; Available at: https://www.cdc.gov/malaria/diagnosis_treatment/clinicians3.html.Dellicour S, Hall S, Chandramohan D, Greenwood B. 2013 Oct 3.Chen LH, Keystone JS. The diagram displays the letter “d” during the human blood stage, or erythocytic cycle, to indicate that this is the diagnostic stage of malaria.This leads into the third cycle, the sporogonic cycle or mosquito stages. It is a lipophilic drug that acts on the intra-erythrocytic asexual stages of parasite development, inhibiting heme polymerization within the food vacuole.Mefloquine is an effective chemoprophylactic and therapeutic agent against drug-resistant For the prevention of chloroquine-resistant malaria, mefloquine is one of several options, along with atovaquone-proguanil, doxycycline or primaquineIn order to assess mefloquine tolerance in those without contraindications (see below),  it is recommended to start mefloquine chemoprophylaxis at least 2 weeks, and preferably 3 weeks, before arrival in an endemic area.
