title: A novel method for collecting and detecting amoxycillin in urine: a tool for testing antibiotic compliance in the community.
abstract: Assessing compliance to prescribed antibiotics in community studies of respiratory tract infections is difficult. We describe a simple method for collecting and detecting amoxycillin in urine using urine dip-sticks in conjunction with a bioassay. Urine was collected at timed intervals from eight healthy volunteers following oral amoxycillin administration. Dip-sticks inoculated with urine collected 1 and 8 h after antibiotic resulted in mean zones of inhibition of 1.75 and 1.37 cm, respectively. Amoxycillin activity remained demonstrable 14 days after inoculation of dip-sticks with urine. Dip-sticks inoculated with urine from control subjects who had not taken amoxycillin did not cause inhibition.
