    Summary
    This summary is machine-generated.

    Predicting the optimal theophylline dose in children (2-13 years) was evaluated. A nomogram method showed a significant correlation between predicted and actual doses for therapeutic theophylline levels.

    Area of Science:

    • Pharmacology
    • Pediatric Medicine
    • Clinical Pharmacy

    Background:

    • Theophylline is a critical medication for pediatric respiratory conditions.
    • Accurate dosing is essential to maximize efficacy and minimize toxicity.
    • Traditional pharmacokinetic methods can be complex for routine clinical use.

    Purpose of the Study:

    • To compare two methods for predicting the optimal theophylline dosage in children.
    • To evaluate the accuracy of a novel nomogram-based approach.

    Main Methods:

    • Assessed a traditional multiple-point pharmacokinetic method for dose prediction.
    • Developed and validated a nomogram using 6-hour plasma concentration and log-dose.
    • Correlated predicted doses with actual doses required for a target concentration (55 mumol/l).

    Main Results:

    • The pharmacokinetic method achieved predicted concentrations within 95% confidence limits on 8 of 14 occasions.
    • The nomogram method demonstrated a significant correlation between predicted and actual theophylline doses.
    • The nomogram effectively related predicted doses to those achieving a target concentration of 55 mumol/l.

    Conclusions:

    • The nomogram method offers a promising, potentially simpler alternative for predicting theophylline doses in children.
    • Further validation of the nomogram is warranted for widespread clinical application.
    • Optimizing theophylline dosing in pediatric patients remains an important clinical challenge.
