'''Pyrantel''' is an [[anthelmintic]] medication used to treat a variety of [[parasitic worm]] infections. It is particularly effective against [[hookworm]]s and [[roundworm]]s. Pyrantel works by paralyzing the worms, which are then expelled from the body through the [[feces]].

Praziquantel (praz" i kown' tel) is a heterocyclic prazino-isoquinoline derivative with a broad spectrum of activity against several trematodes (Fasciola, Schistosoma) and cestodes (Taenia). Praziquantel is believed to act by interference with tegument calcium transport, resulting in paralysis of the parasitic worms with subsequent loss of adherence to tissue, degradation and expulsion.  
Pyrantel acts as a [[neuromuscular blocking agent]] in susceptible parasites. It causes a depolarizing neuromuscular blockade, leading to spastic paralysis of the worm. This paralysis allows the host's natural peristaltic action to expel the worm from the [[gastrointestinal tract]].
