Pharmacokinetics-based analysis of indomethacin's anti-tumor effect and drug efficacy.

Non-steroidal anti-inflammatory drugs are commonly used anti-inflammatory analgesics in clinic. Indomethacin is a kind of NSAIDs and has anti-tumor effect. It can significantly change the growth cycle of cancer cells, inhibit their proliferation. In this paper, the antineoplastic effect of indomethacin and its pharmacokinetic effect were analysed. The result showed that indomethacin had more metabolic distribution in tumor tissues and reached its peak at 4 hours, after that, the clearance rate was slower than that in the blood, with the clearance rate slowest at 6-12 hours. At the same time, the expression of Bcl-2 protein in cancer cells was significantly reduced and weakened, while the expression of Bax protein did not change significantly. Pharmacodynamic studies have proved that IN (Indomethacin) has a strong anti-tumor effect. It can enter into tumor cells through cell membrane and nuclear membrane to have an anti-tumor effect.
