Abstract | The binding of two non-steroidal anti-inflammatory drugs, indomethacin and cinmetacin, to human serum albumin was studied by dynamic dialysis at 37 degrees C and pH 7.4. Cinmetacin is bound more than indomethacin. The affinity constant for the primary binding site is 4.28 X 10(6) M-1 for cinmetacin and 1.4 X 10(6) M-1 for indomethacin. The protein binding of indomethacin is decreased in the presence of cinmetacin. |
