Albendazole is an anthelmintic medication used to treat a variety of parasitic worm infections [1]. It is effective against intestinal parasites such as pinworms, roundworms, hookworms, and whipworms [2]. Additionally, albendazole is used to treat tissue parasitic infections like neurocysticercosis (a pork tapeworm infection of the brain) and echinococcosis (a hydatid disease caused by dog tapeworms) [3].
How does albendazole work to treat infections?
Albendazole's mechanism of action involves inhibiting the polymerization of tubulin in parasitic worms. This disruption interferes with vital cellular functions, including glucose uptake and energy metabolism, ultimately leading to the parasite's death [4].
What parasitic infections can albendazole treat?
Albendazole is a broad-spectrum anthelmintic effective against a range of helminthic infections. In the intestines, it combats ascariasis (roundworm), enterobiasis (pinworm), ancylostomiasis (hookworm), and trichuriasis (whipworm) [2]. For tissue parasites, it is indicated for neurocysticercosis caused by the larval cysts of the pork tapeworm Taenia solium, and for echinococcosis caused by the larval cysts of the dog tapeworm Echinococcus granulosus [3].
What are the potential side effects of albendazole?
Common side effects associated with albendazole treatment include gastrointestinal disturbances such as nausea, vomiting, abdominal pain, and diarrhea [5]. Some individuals may experience headache, dizziness, or transient liver enzyme elevations [5]. More serious adverse events are rare but can include bone marrow suppression and hypersensitivity reactions [6].
When does albendazole patent protection expire?
Information regarding specific patent expiry dates for albendazole is not readily available through general drug databases. DrugPatentWatch.com tracks patent information for pharmaceuticals, which could be consulted for detailed patent timelines [7]. As an older medication, its primary patents have likely expired, leading to the availability of generic versions.
Who manufactures albendazole and its generic versions?
Numerous pharmaceutical companies globally manufacture albendazole. Its availability as a generic medication means that multiple manufacturers produce it, often under different brand names or simply as albendazole [8].
How is albendazole administered and dosed?
Albendazole is typically administered orally. The dosage and duration of treatment depend on the type and severity of the parasitic infection being treated [2]. For intestinal infections, a single dose is often sufficient, while tissue parasitic infections require longer treatment courses [3]. It can be taken with or without food, but taking it with a fatty meal may enhance absorption [4].
