Hypertension (HT) is a very common disorder, particularly for past middle age. It is not a disease in itself, but is an important risk factor for cardiovascular mortality and morbidity. For improved treatment of hypertension, Telmisartan and Benidipine HCl is the newer combination in market, this combination was developed to improve medication for Stage II hypertension. The aim of this review is to focus on comprehensive update of different analytical methods used for estimation of anti-hypertensive drugs like Telmisartan and Benidipine HCl for the treatment of hypertension. This review delivers a detail description on different analytical methods like UV and RP-HPLC for Telmisartan and Benidipine HCl individually and combination with other drugs. For this review, data searches were conducted by scientific papers in the literature as well as in official compendium. All reported methods are found to be simple, accurate, economic, precise and reproducible in nature.

A pestle and mortar-assisted solvent-free condensation of salicylaldehyde and 2-aminopyridine efficiently afforded a NO donor Schiff base ligand in high yield. This is an environmentally benign method, as satisfactory results were obtained in solvent free conditions with excellent yields, short reaction time, and operational simplicity in the experimental procedure. Copper(II) complex of this ligand were synthesized. Schiff base ligand and its complex were characterized by their melting point, elemental analysis, IR and 1H NMR spectra. In addition, DNA-binding properties of the metal complex were investigated using absorption spectroscopy, viscosity measurements and thermal denaturation methods. The DNA photoclevage experiment shows that, the complex act as effective DNA cleavage agent.
