Flubendazole is an anthelmintic that is used to treat worm infection in humans. It is available OTC in Europe. Flubendazole is registered and sold in Europe (EMEA) as Fluvermal (Johnson and Johnson, Sante Bea). A 100mg dose of Fluvermal is most commonly proscribed for treating pinwoms (Enterobius vermiculus)). This is followed by a second dose of 100mg 15-21 days later to ensure reinfection is avoided, as flubendazole does not kill pinworm eggs. 100mg taken 3 times a day for 3 days is effective against larger nematodes, but only marginally effective against tapeworms. Flubendazole was validated for its anti-proliferative efficacy in MDA-MB-231 cells. Moreover, Flubendazole induced autophagy and increased ROS production. In silico analysis and experimental validation together demonstrate that Flubendazole can target autophagy-related protein 4B (Atg4B) in MDA-MB-231 cells and induce autophagy, which may shed light on the exploration of this compound as a potential new Atg4B targeted drug for future triple-negative breast cancer (TNBC) therapy.

Route of Administration: Oral
Protoscoleces of E. granulosus were incubated with flubendazole (FLBZ) at concentrations of 10, 5 and 1 uM. The first signs of FLBZ-induced damage were observed 3 days post-incubation. A clear protoscolicidal effect, reducing the vitality of protoscoleces to 35.6+/-0.7%, was observed after 18 days of incubation. After 25 days of FLBZ incubation (5 uM), the percentage of vital protoscoleces was 13.9+/-5.9%. Protoscolex mortality was 100% (10 and 1 ug/L) and 0.7+/-0.7% (5 ug/ml) after FLBZ incubation for 30 days.
