Abstract
Sustained release preparations are expensive and experience with them is but little. A clear indication is needed for the application of sustained release preparations. After administration of quickly releasing preparations to patients with a rapid elimination, risk occurs for too large differences in peak and trough concentrations. Nevertheless a medication schedule of twice a day is desirable in view of the patient compliance. The application of sustained release preparations twice a day is justified for patients with an elimination half-life less than eight hours. This is generally the case with children. For adults it can be calculated that sustained release preparations are only indicated if more than 10, resp. 15 mg per kg body weight per day is needed to obtain a serum theophylline concentration of 10, resp. 15μg/ml in steady state.
Promising preparations, available on the American market, are Slophylline®, Theolair sr® and Theodur®4.
