A validate rapid, economical and sensitive visible spectrophotometric method has been developed for quantitative determination of amprenavir in bulk drug and tablet samples.This method is validated for irinotecan with chromogenic reagent namely bromo cresol green (BCG) at λ max 417. The calibration curve was linear over a concentration range of 5-40 µg/ml. The relative standard deviation (R.S.D) is less than 1% and average recovery was above 99.60%. Efficient visible spectrophotometric detection at λmax 417nm enabled determination of the drug with no interference from tablet excipients. The pr

Many researchers also have coupled these instrumental techniques with chemometric algorithms to assist in the quantitative analysis of multi-component samples in the hope of alleviating the need of tedious separation and cleanup procedures. These newer chemometric procedures tend to be complex and difficult to understand and implement and are successful under different circumstances and conditions.

The primary advantages of optical measurements are that they are general, convenient, nondestructive, and can yield information about dynamic systems or processes in real time and in any transparent ambient. No special sample requirements are needed other than a reflecting surface, and measurements can be made with the sample in air or in atmospheric-pressure ambients. Nondestructiveness is obviously important for the analysis of unstable materials systems such as interfaces buried under oxide overlayers, while real-time capabilities suggest useful applications in process control.

Abstract:
Due to the medical importance of Pepcid, a spectrophotometric method had been suggested for the determination of Pepcid in its pure form as well as in some of its pharmaceutical preparations. The proposed method relies on two important steps; the first one, is the oxidation-reduction reaction between Pepcid and an amount of cerium IV (oxidizing agent) in presence of acidic medium, followed by the second step that occurs between cerium (III) with safranin, at the selected wavelength 514 nm. The proposed method obeyed Beer's law within the range (2-40) µg.mL-1, with good sensitivity relative to
