Qualitative and quantitative estimation plays a significant role in ensuring safety and efficacy of drugs in different matrices. A detailed literature survey is one of the most crucial requirement for all research activities. Efonidipine (EFN) is a new antihypertensive agent that inhibits both L-type and T-type calcium channels. It was launched in 1995, under the brand name of Landel, and marketed by Shionogi and Co. On August 28, 2017, the Drug Controller General of India (DCGI) granted the approval of the drug in India under the brand name of Efnocar to Zuventus Healthcare Ltd. This article examines published physical properties, pharmacokinetic data, analytical methods, and clinical trials reported in the literature for the determination of EFN in biological samples and pharmaceutical formulations. They include various techniques such as fluorescence spectroscopy and circular dichroism, thermal analysis, Fourier transform infrared spectroscopy, evolved gas analysis, environmental scanning electron microscopy, X-ray diffraction, spectrophotometry, high-performance liquid chromatography, and LC-MS/MS. There is no marketed formulation available in combination of EFN with other drugs, but recently Ajanta Pharma got approval for the combination of EFN with telmisartan in tablet form.
