Simultaneous Determination of Losartan and Hydrochlorothiazide in Pharmaceutical Preparations by Derivative and Ratio Derivative Spectrophotometry
Background & Aims: Losartan is a non-peptide potent antihypertensive agent that acts through blocking angiotensin II receptors. Hyzaar® is a combination product that contains two drugs, losartan and hydrochlorothiazide, used to lower high blood pressure. There are some reports regarding simultaneous measurement of the drugs in pharmaceutical and biological samples which includes HPLC, CE, CEC, ...
متن کاملDetermination of Ascorbic Acid in Vegetables by Derivative Spectrophotometry
Determination of ascorbic acid (AA) in garlic, green pepper and chestnut was performed by derivative spectrophotometry without using any pre-separation or background correction techniques. The method is based on the measurement of the distances between two extremum values (peak-to-peak amplitudes) in second and third order derivative spectra of the extracts. Ten percent trichloroacetic acid was...
متن کاملDetermination of iron in biological material by spectrophotometry of ferric perchlorate.
3. The presence of equimolar concentrations of pyridoxal phosphate prevented the inhibition by isoniazid. Stable hydrazones of isoniazid did not inhibit transaminase activity. These compounds, which were stable in the presence of heavy suspensions of B.C.G. organisms, had tuberculostatic activity comparable with isoniazid. 4. Transaminase activity was found in extracts of cells which had been e...
متن کاملDetermination of plasma protein-bound malondialdehyde by derivative spectrophotometry.
We describe a method for the measurement of protein-bound malondialdehyde with the thiobarbituric acid reaction in human plasma using second-derivative spectrophotometry. Calibration was done by spectrum height measurement from the baseline at 532 nm. The data were compared with those obtained by using conventional absorbance and fluorimetric measurements. The results were linear from 0.2 to 80...
