Albendazole and fenbendazole both belong to the benzimidazole class of anthelmintic drugs, sharing a similar core chemical structure and mechanism of action. However, despite these chemical similarities, significant differences in their bioavailability and approved applications mean the two medications are not interchangeable, particularly concerning their use in humans versus animals.

Over 1 billion people worldwide are affected by soil-transmitted helminth infections, often treated with drugs from the benzimidazole class, which includes albendazole. This leads many to question: **Is albendazole the same as fenbendazole?** The answer is no, despite their common origin and structural similarities.
