Analytical Methods of Dihydropyridines Based Calcium Channel Blockers - Amlodipine, Lacidipine, Isradipine, Nifedipine, Felodipine, Cilnidipine and its related formulations: A Review

Abstract

Objectives: Various analytical techniques are applied in pharmaceutical field to estimate the quality of active pharmaceutical ingredients, amount of drug in biological fluids and in formulations. The aim of this review article is to provide utmost existing analytical methods for analysis of dihydropyridines based calcium channel blockers for estimation of Amlodipine, Lacidipine, Isradipine, Nifedipine, Felodipine, and Cilnidipine in pure form, biological fluids (like Human Plasma, Human Serum, Human Urine etc.,) and its related formulations including novel formulations. Dihydropyridines based Calcium Channel blockers is a major chemical class of drugs used in the treatment of hypertension and various coronary artery diseases. Evidence acquisition: Current analytical techniques available for active pharmaceutical ingredients and its related formulations are tabulated with extensive method conditions which can be used in analysis of dihydropyridines based calcium channel blockers drugs outlined from official pharmacopoeias and other relevant research articles. Conclusion: Various analytical techniques such as HPLC, HPTLC, UPLC, GC, LC-MS, and GC-MS are involved. This review assists in appropriate selection of analytical technique, solvent, mobile phase, column, detector based on available analytical instruments and chemicals, by referring tabulated extensive method conditions. It can be implemented in quality control and quality assurance department for quality assessment of diverse pharmaceutical formulations.
