  双氯芬酸
    In supporting solution of 0.3 mol/L H2SO4,the oxidation peak potential of diclofenac sodium was at 0.48 V(vs.SCE). The oxidation peak current is linear with the concentration of diclofenac sodium in the range from 3.0×10-7 to 1.0×10-5mol/L. The detection limit is about 1.0×10-7mol/L for 2 min accumulation.

  diclofenac
Diclofenac (25 mg kg-1) and meloxicam (7.5 mg kg-1) produced 9.3 and 19.6 mm2 ulcer areas in stomachs of rats, respectively, when used alone, but when combined with nimesulide diclofenac and meloxicam did not cause any injury in rat stomachs.
      
While ranitidine at 100 mg kg-1 dose prevented diclofenac-induced ulcer formation, it reduced meloxicam-induced ulcer formation significantly.
      
Determination of diclofenac in pharmaceuticals and urine samples using a membrane sensor based on the ion associate of diclofena
      
The potentiometric response characteristics of a diclofenac selective electrode, based on ion association in different plasticizers, were compared.
      
The potentiometric unit presented a linear response toward diclofenac concentrations between 1 × 10-5 - 5 × 10-2 mol L-1, with slopes of approximately 60 mV dec-1, and exhibited a response time of 3 s.
