Determination of Aminophylline by Cathodic Stripping Voltammetry
Aminophylline is determined by cathodic stripping voltammetry (CSV) in BR buffer, pH 7.5 at a hanging mercury drop electrode. The detection limit was 3x10 M after 60 s accumulation at -0.60 V versus Ag/AgCl reference electrode. The linear range demonstrated up to 5x10 M using CSV. The interference caused by some purine derivatives, anions and some metal cations on the peak current was studied. ...
متن کاملReliability of theophylline clearance in determining maintenance intravenous aminophylline therapy.
A lthough theophylline has long been the primary drug used for the management of reversible obstructive airway disease, current recommendations for determining theophylline dosage have not been dependable and, when applied to individual patients, have resulted in a wide range of serum theophylline concentrations (STC) and frequent adverse reactions.1-3 The objective of this study was to evaluat...

متن کاملDose conversion from aminophylline to theophylline in preterm infants.
Twenty two preterm infants were prospectively evaluated to assess the need for dose adjustment when converting enteral and parenteral routes of methylxanthine administration. Serum theophylline concentrations remained unchanged in 18 infants after conversion from intravenous aminophylline to theophylline by mouth with dose reduction, as is currently recommended. Intravenous aminophylline and th...
