Role of the Abcg2 transporter in plasma, milk, and tissue levels of the anthelmintic monepantel in mice.

Breast cancer resistance protein/ATP-binding cassette subfamily G2 (BCRP/ABCG2) is an ATP-binding cassette efflux (ABC) transporter expressed in the apical membrane of cells in tissues, such as the liver, intestine, kidney, testis, brain, and mammary gland. It is involved in xenobiotic pharmacokinetics, potentially affecting the efficacy and toxicity of many drugs. In this study, the role of ABCG2 in parasiticide monepantel (MNP) and its primary metabolite, monepantel sulfone (MNPSO)'s systemic distribution and excretion in milk, was tested using female and male wild-type and Abcg2 mice.

Effects of feed intake and water hardness on fluralaner pharmacokinetics in layer chickens.

Background: Fluralaner is a novel drug belonging to the isoxazoline class that acts on external parasites of domestic animals. It is used systemically via drinking water, especially against red poultry mite in layer chickens. Fluralaner is frequently used in layers infected with .

Response of cultured normal canine mammary epithelial cells to deracoxib-doxorubicin combination.

Currently, there is a growing interest in combining anticancer drugs with the aim to improve outcome in patients suffering from tumours and reduce the long-term toxicity associated with the current standard of treatment. In this study, we evaluated the possible role of deracoxib against the toxicity of doxorubicin on normal canine mammary epithelial cells. The effect of deracoxib and doxorubicin combination on cell viability was determined by MTT assay.
