A green, sensitive and cost-effective method is introduced in this research for the determination of bambuterol and its main degradation product; terbutaline simultaneously relied on the synchronous spectrofluorimetric technique. First derivative synchronous spectrofluorimetric amplitude is measured at Δλ=20 nm, so bambuterol can be quantitated at 260 nm, and terbutaline can be measured at 290 nm, each at the zero crossing point of the other. The amplitude-concentration plots were linear over the concentration ranges of 0.2-6.0 g/mL and 0.2-4.0 g/mL for both bambuterol and terbutaline, respectively. Official guidelines were followed to calculate the validation parameters of the proposed method. The low values of LODs 0.023, 0.056 g/mL and LOQs 0.071, 0.169 g/mL for bambuterol and terbutaline, respectively point out to the sensitivity of the method. Bambuterol is a prodrug for terbutaline, and the latter is considered its degradation product so the established method could be regarded as a stability-indicating one. Moreover, the proposed method is utilized for the analysis of BAM and TEB in their single ingredient preparations and the results revealed statistical agreement with the reference method. The suggested method, being simple and low cost procedure, is superior to the previously published methods which need more sophisticated techniques, longer analysis time and highly toxic solvents and reagents. It could be considered as an ecofriendly analytical procedure.
