A program that calculates a value of clearance for an individual patient prior to reaching steady state in the early stages of aminophylline therapy is presented. The program is written for the Texas Instruments TI-59 programmable calculator and may be used with or without the PC-100C printer. The program can provide clinically useful information concerning projected plasma concentrations prior to reaching steady state with an accurate history of the dose administration and serum concentration determination. If the patient has not received xanthene therapy prior to admission, only one serum sample is required. If there has been prior drug exposure, a second serum sample is required. An iterative technique, which would be impractical to use without calculator assistance, is employed to make these determinations.

To the Editor.— I believe there is an error in the article entitled "A System for Individualized Dosing of Intravenous Aminophylline Using a Programmable Calculator" by J. Chris Mitsuoka and Richard J. Fleck (Pediatrics 1984;73:64-67). In the first equation, the first term Cpo e-Ke(t-t') should be Cpo e-Ke(t + t') if t represents the time elapsed after the infusion has commenced. The paper is confusing as to exactly what t represents; the authors state "duration of therapy" but does therapy begin with the loading dose or with the infusion.
