Pyrvinium is an anthelmintic drug primarily used to treat pinworm (Enterobius vermicularis) infections. It has been used for intestinal parasite infections, particularly in children. Its use has decreased in recent decades in many countries and it is not widely marketed or approved in the United States or Europe today.
Pharmacokinetics
There are currently no published human pharmacokinetic studies reporting specific pharmacokinetic parameters for pyrvinium. It is reported to have poor gastrointestinal absorption following oral dosing, with most of the drug staying within the gastrointestinal tract.
