Every year many new drugs and newer drug combinations enter the pharmaceutical area. Analytical methods for these new and first timer drugs are mostly confined only to the manufacturing company. However, availability of multiple analytical methods for the same drug/drug combinations in their formulations is always advantageous. Moreover, development of such methods helps in training the analysts for skillfully handling the sophisticated analytical instruments and the way for research approach. The present work is also planned on similar lines. A simple, precise, rapid and accurate...

A successful attempt was made for the spectrophotometric quantitative estimation of two antihypertensive marketed combinations using mixed hydrotropic agent. The method was developed by experimentation based on thorough literature survey and ascertained by statistical parameters of sampling. The entire work was performed on Shimadzu UV/VIS double beam-double detector spectrophotometer (Model-1700 series). The result obtained shows the developed method to be precise, simple, rapid and accurate. Thus these can be used for routine analysis of Eprosartan, Hydrochlorothiazide, and Olmesartan...
