• 产品描述： Tolmetin sodium dihydrate is an orally active and potent COX inhibitor with IC50s of 0.35 µM and 0.82 µM human COX-1 and COX-2, respectively. Tolmetin sodium dihydrate is a non-steroidal anti-inflammatory drug (NSAID)

• 靶点： Human COX-1:0.35 μM (IC50);Human COX-2:0.82 μM (IC50)

• 体内研究：
  Tolmetin sodium dihydrate (30,100 mg/kg; gavage; single dose or twice daily for 3 and 14 days) shows maximal ulcerogenic effect 4 h after the single dose, while potently decreases after 3 and 14 days of repeated administration in male Wistar rats weighing 180-200 g. Tolmetin causes gastric lesions in 100 mg/kg. Tolmetin sodium dihydrate (5 mg/kg twice a day for 5 days) pre-treatment considerably attenuates quinolinic acid (QA)-induced neurotoxicity
