How to use

In Vitro:

The transport of radiolabelled Selamectin through Caco-2 monolayers shows that Selamectin is P-glycoprotein (P-gp) substrates with a secretory/absorptive ratio of 4.7. Selamectin inhibits the efflux of Rh-123 from peripheral blood lymphocytes (PBL) and the concentration of inhibition is similar to that of Verapamil[2].

In Vivo:

A single administration of 6 mg/kg topical Selamectin given every two months could effectively prevent B. malayi infection in cats. Application of topical Selamectin twice a year could block circulating microfilariae[1].
