Abstract
Butanol and dilute sulfuric acid were used to extract paromomycin and gentamicin from Aquaphilic®-based formulated creams. The extraction procedure was validated over different antibiotic concentration ranges for linearity, precision, accuracy, limited specificity, sensitivity and solution stability.
