Rapidly absorption occurs and attains high plasma concentration occurs within 2 hours. Effects of food: food will decrease the rate but not all the extent of anastrazole absorption.
The drug anastrazole has human serum protein bound is 40%
The anastrazole metabolism is occurred via N-Dealkylation, hydroxylation and Glucuronidation The metabolites of anastrazole are; Triazole-major circulating metabolite which has poor pharmacological activity A glucoronide conjugate of hydroxyl anastrazole A glucoronide conjugate of anastrazole
Nearly 85% of anastrazole reclaimed in feces and urine in Hepatic metabolism: 10% total clearance in Renal metabolism The anastrazole half life is 50 hours
