“The potential anticancer effects of piroxicam in cats with transitional cell carcinoma have not been thoroughly described, but, anecdoctally, piroxicam appears to be well-tolerated at a dosage of 0.3 mg/kg by mouth two or three times a week. Using this dosing scheme in cats with transitional cell carcinoma should be safe based on prior pharmacokinetic studies of oral piroxicam conducted in healthy cats; however, its anticancer effectiveness remains poorly characterized in cancer-bearing cats.”
