Pirantel Pharmacodynamics
Pirantel is an anthelmintic agent acting on nematodes.
It causes neuromuscular blockade in helminths sensitive to it, which facilitates their elimination from digestive tract without agitation and stimulation of migration of affected worms.
The drug acts on parasites in the early phase of development and on their mature forms, it has no effect on larvae during their migration in tissues.
Pirantel is effective against infestations caused by pinworms (Enterobius vermicularis), ankylostomes (Ancylostoma doudenale, Necator americanus), trichocephalosis (Trichocephalus trichiurus) and ascariasis (Ascaris lumbricoides).
