title: Studies on absorption and elimination of drugs. Part VI: Fitting of a double exponential curve to the observed drug concentration after single extravascular administration.
abstract: A simple program was written in Algol 1204 for the Polish digital computer ODRA 1204. It permits the fitting of the Bateman equation C equals const [e-KEt -- e-KAt] or the equation C equals Be-KEt -- Ae-KAt to the observed plasma or serum concentration data after single extravascular administration of a drug. The results obtained with this M-31 program, compared with the calculations of the pharmacokinetic parameters for tetracycline HCl obtained with the Wagner's Nonline or Lag Time program, show a good conformity.
