ATP-binding cassette (ABCG2) is an efflux transporter that extrudes xenotoxins from cells in liver, intestine, mammary gland, brain and other organs, affecting the pharmacokinetics, brain accumulation and secretion into milk of several compounds, including antitumoral, antimicrobial and anti-inflammatory drugs. The aim of this study was to investigate whether the widely used anti-inflammatory drug meloxicam is an Abcg2 sustrate, and how this transporter affects its systemic distribution. Using polarized ABCG2-transduced cell lines, we found that meloxicam is efficiently transported by murine Abcg2 and human ABCG2. After oral administration of meloxicam, the area under the plasma concentration-time curve in Abcg2-/- mice was 2-fold higher than in wild type mice (146.06 ± 10.57 μg·h/ml versus 73.80 ± 10.00 μg·h/ml). Differences in meloxicam distribution were reported for several tissues, with a 20-fold higher concentration in the brain of Abcg2-/- compared to wild-type mice. Meloxicam secretion into milk was also affected by the transporter, with a 2.5-fold higher milk-to-plasma ratio in wild-type compared with Abcg2-/- lactating female mice (0.58 ± 0.08 versus 0.23 ± 0.06). We conclude that Abcg2 is an important determinant of the plasma and brain distribution of meloxicam and is clearly involved in its secretion into milk.
