A simple UV spectrophotometric method for theophylline serum level determination.
A brief, simple and unexpensive UV spectrophotometric method for theophylline serum level determination is described. Charcoal extraction was performed for theophylline isolation from biological fluids. Coefficients of variation and recovery are similar to other parallel methods.
