A hollow fiber culture mimics human mefloquine exposure to track malaria parasite kill
- A plastic hollow fiber system sustained blood-stage P. falciparum growth through two full life cycles, matching static controls.
- Programmed dilution reproduced simulated human mefloquine plasma profiles, including its long half-life, from published patient PK models.
- Under this exposure, parasitemia stayed suppressed across cycles, in line with concentration-driven activity, supporting PK/PD-guided antimalarial dosing.
💡 Points
Mefloquine's long half-life is exactly what makes a static assay misleading, so a system that reproduces the human exposure curve is the right kind of tool. But I'd want to see it break: does it separate partial from full kill, and how does it handle resistant parasites? Suppression of parasitemia alone doesn't tell me about recrudescence, and none of this speaks to the neuropsychiatric liability that limits the drug in people.
