Pyrantel Pamoate tablets

DIN 02184605


Pyran 125 (Pyrantel Pamoate) is an anthelmintic. It is a crystalline, water insoluble, tasteless salt of tetrahydropyrimidine base and pamoic acid with the name Trans-1,4,5,tetrahydro-1-methyl-2-(2-(2-thienyl)-vinyl)-pyrimidine hydrogen pamoate. Pyrantel Pamoate formula is C11H14N2S.C23H16O6 and its molecular weight is 594.686.

MODE OF ACTION: Pyran 125 has an anthelmintic effect by interfering with the neuro-muscular function of the parasite.


Pyran 125 is available as a small orange scored tablet containing Pyrantel Pamoate equivalent to 125 mg of Pyrantel base per tablet.

Pyran 125 Tablets Indications

Pyran 125 tablets are indicated for the treatment of parasite infestations in dogs, puppies and cats:



Dogs and Puppies


Toxocara cati

Toxocara canis

Toxascaris leonina


Ancylostoma spp

Ancylostoma caninum

Uncinaria stenocephala

While Pyran 125 is not effective in removing whipworms (Trichuris vulpis) from dogs, treatment will result in a significant egg count reduction. Pyran 125 is ineffective in the control of tapeworms.


There are no known contraindications.

Pyran 125 Tablets Caution

The same precautions should be taken with Pyran as with other cholinesterase inhibitors.


The anthelmintic activity of Pyran 125 has been demonstrated in several laboratory model infections utilizing mice, rats and dogs. These tests showed the compound to be effective for the control of hookworm and roundworm infestations. Pyran 125 is poorly absorbed by the intestinal mucosa so that its activity is confined to the lumen of the bowel. In the dog the peak plasma levels were low, and similarly the tissue levels were low. Less than 15% is excreted via the urine, the major proportion of the dose being excreted in the feces.

Pyran 125 Tablets Dosage And Administration
