Amlodipyric acid solution is primarily used in research settings for its potential cardiovascular effects. It serves as an analytical reference standard in pharmaceutical testing and quality control, particularly in studies related to calcium channel blockers. The solution form allows for precise dosing in in vitro experiments, supporting investigations into vascular smooth muscle relaxation and blood pressure regulation. It is also utilized in method development for drug detection and quantification in biological matrices, aiding pharmacokinetic and metabolic studies. Due to its stability in solution, it is suitable for high-performance liquid chromatography (HPLC) calibration and validation processes in laboratory environments.
