Feeding time
It is not known whether pyrantel pamoate is excreted in human milk. Breastfeeding should therefore be discontinued if use of the drug is deemed essential.

05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
ATC code: P02CC01.
Pyrantel pamoate has shown a high anthelmintic efficacy against infections caused by Enterobius vermicularis (pinworm) eAscaris lumbricoides (ascaris).
Pyrantel pamoate exerts a neuromuscular blocking effect on sensitive helminths. Thanks to this activity, pyrantel pamoate immobilizes roundworms and causes their expulsion without stimulating the rate of spread of parasites. In the intestinal tract, pyrantel pamoate is effective on both mature and immature forms of sensitive helminths, while the migrant forms are not affected.
05.2 Pharmacokinetic properties
Pyrantel pamoate is poorly absorbed from the gastrointestinal tract. After a single oral administration of 11 mg / kg, plasma levels of unchanged drug lower than 0.05-0.13 mg / ml are obtained. The absorbed portion is rapidly metabolised and only 1% of the administered dose is excreted unchanged in the urine and 3% in the form of metabolites.
05.3 Preclinical safety data
The LD50 after single oral administration in cats, mice and dogs varies from 2 to 5 g / kg while after single intramuscular administration it is 250 mg / kg in cats and 198 mg / kg in mice.
Chronic toxicity
In one study, 60 rats were treated with doses of 100, 300 or 600 mg / kg / day, respectively, over a period of 13 weeks. No changes referable to pyrantel pamoate emerged from the anatomo-pathological investigation or to the microscopic examination of the tissues.
In another study, beagle dogs were treated with doses of 100, 300, or 600 mg / kg / day over a period of 13 weeks. At the end of the study period, mild and apparently dose-dependent lymphocytosis and an increase in serum transaminases were detected in 5 dogs.
There were no histopathological changes referable to the drug.
Teratogenesis
There were no effects on fertility, reproduction, organogenesis, parturition or lactation in rats treated with doses of 25 or 250 mg / kg. Furthermore, no effects on organogenesis were found in rabbits treated with the same doses.
