Background

Etoricoxib (MK-0663) is a non steroidal anti-inflammatory agent, acting as a selective and orally active COX-2 inhibitor, with IC50s of 1.1 μM and 116 μM for COX-2 and COX-1 in human whole blood.


Etoricoxib (MK-0663) is a selective and orally active COX-2 inhibitor, with IC50s of 1.1 μM, 116 μM and 5 μM for COX-2, COX-1 in human whole blood and purified human COX-2, respectively. Etoricoxib (MK-0663) shows inhibitory effect on PGE2 production by CHO (COX-2) cells (IC50, 79 nM), on purified human COX-2 with detergent (IC50, 4.1 μM), and on purified PGE2 production by U937 microsomes (low substrate; IC50, 12.1 μM). However, Etoricoxib (MK-0663) has little activity against COX-1 with a Ki of 167 μM[1].


Etoricoxib (MK-0663) (0.1-30 mg/kg, p.o.) dose-dependently inhibits carrageenan-induced paw edema, carrageenan-induced paw hyperalgesia, and endotoxin-induced pyresis in rats. Etoricoxib (≥10 mg/kg) completely reverses hyperalgesia response in the rat hyperalgesia model. Etoricoxib (MK-0663) (200 mg/kg/day) has no effect on urinary 51Cr excretion in rats, and nor in monkeys at 100 mg/kg/day[1]. Etoricoxib (MK-0663) (50 and 100?mg/kg) potently increases the malondialdehyde (MDA) and myeloperoxidase (MPO) levels, and decreases the total glutathione (tGSH) and glutathione reductase (GSHRd) levels in rats. Etoricoxib (MK-0663) (100?mg/kg) significantly inhibits the decrease of NO in rats[2]. Etoricoxib (MK-0663) (0.64 mg/kg, p.o.) reduces the features such as multiple plaque lesions, hyperplasia and dysplasia induced by 1,2-dimethylhydrazine dihydrochloride (DMH) in rats[3].

Protocol

Animal experiment:

Rats[3]Animals are assorted into the following groups with four to six animals in each group: Control Group, Animals are administrated the vehicle (1mM EDTA-saline subcutaneously) in weekly injection and 0.5% carboxymethyl cellulose per oral daily; 1,2-dimethylhydrazine dihydrochloride (DMH) Group, animals are administrated with DMH weekly at a dose of 30 mg/kg body weight subcutaneously, DMH is freshly prepared in 1mM EDTA-saline, pH adjusted to 7.0 using dilute NaOH solution; DMH + Etoricoxib Group, Etoricoxib (MK-0663) is given daily per oral at its therapeutic anti-inflammatory dose (ED50 for rats, 0.64 mg/kg body weight) to the animals along with the weekly administration of DMH; and Etoricoxib Group: Etoricoxib (MK-0663) alone is administered orally daily (0.64 mg/kg body weight). After six weeks, animals are kept on overnight fasting with drinking water ad libitum and sacrificed the next day. The animal body weights in all the groups are recorded once in a week till the termination.[3].
