Abstract
This study presents a sustainable electrochemical investigation of pramipexole (PRA) in pharmaceuticals and human plasma, using cyclic and differential pulse voltammetry. Key parameters, including potential range, buffer pH, accumulation period, and scan rate were optimized, establishing efficient voltammetric methods for PRA analysis. The analytical range was 0.60–12.00 μg ml−1, with a detection limit of 0.14 μg ml−1 and a correlation coefficient of 0.9998. Recovery rates for PRA ranged from 98.60 ± 0.26% to 101.33 ± 0.38%, validating the methodology’s applicability in human plasma with an average recovery of 99.25 ± 0.45%. The study highlights the environmental sustainability of the developed voltammetric electrode, evaluated through SWOT analysis, and assesses the greenness impact using tools like Complementary Green Analytical Procedure Index (ComplexGAPI), Analytical greenness (AGREE) and Analytical greenness for sample preparation (AGREEprep). Significantly, this work aligns with numerous United Nations Sustainable Development Goals (UN-SDGs), specifically goals 3, 4, 5, 7, 9, 11, 12, 13, 14, 15, and 17, illustrating our commitment to sustainable pharmaceutical research. The sustainability of the method was further quantified using the newly introduced Need, Quality, Sustainability (NQS) index, demonstrating significant alignment with sustainable analytical practices.
