    Two methods of predicting the optimal dose of theophylline in children aged 2 to 13 years were assessed. The observed plasma concentration was within 95% confidence limits of that predicted on eight of 14 occasions using a traditional multiple point pharmacokinetic method. Using a nomogram derived from the plasma concentration 6 hours after dosing and the logarithm of the calculated dose, which were significantly correlated, there was a significant relation between the dose predicted and the actual dose required to produce a concentration of 55 mumol/l.
