Cyclic voltammetry (CV) offers a rapid method for evaluating antioxidants in pharmaceutical formulations by measuring oxidation potentials. This technique can quickly identify optimal antioxidants for drug stability studies.
Area of Science:
- Electrochemistry
- Pharmaceutical Science
Background:
- Cyclic voltammetry (CV) is an electrochemical technique used for compound characterization.
- It is widely applied in various industries for antioxidant evaluation but underutilized in pharmaceutical formulation.
- This review explores CV's principles, applications, and potential in pharmaceuticals.
Purpose of the Study:
- To review the principles and applications of CV in other industries.
- To assess the potential and limitations of CV for rapid antioxidant evaluation in pharmaceutical formulations.
- To highlight the correlation between antioxidant oxidation potentials and efficiency.
Main Methods:
- Literature review of CV principles and applications.
- Survey of studies correlating antioxidant oxidation potentials with antioxidant efficiency.
- Analysis of CV's suitability for pharmaceutical formulation development.
Main Results:
- A strong correlation exists between the oxidation potentials of antioxidants and their efficacy.
