Widely used as an anthelmintic agent, effective against intestinal parasitic infections such as pinworm (Enterobius vermicularis), roundworm (Ascaris lumbricoides), and hookworm (Ancylostoma duodenale and Necator americanus). It works by paralyzing the worms through depolarizing neuromuscular action, leading to their expulsion from the gastrointestinal tract. Commonly formulated in oral suspensions, tablets, or chewable forms for pediatric and adult use. Frequently used in mass deworming programs due to its safety profile and efficacy. Also used in veterinary medicine for treating parasitic worm infections in cats and dogs.
