Estimation of Nateglinide by using MBTH as a Chromogenic Reagent

Fabrication a novel ethylenediamine sulfonamide polymer resin and graphene-modified carbon paste electrodes for simultaneous determination of anti-HBV drugs entecavir and tenofovir in dosage form by differential pulse voltammetry

“…Among these there are spectrophotometry, chromatography, and electrochemistry methods. ETV was determined at 437 nm and 293.6 nm by spectrophotometric methods, with a linear range of 1.4-6.8µM [15] and 1.7-17.0µM [18] and LODs of 0.5µM and 0.06µM, respectively. TEV was determined at a range of wavelengths around 229-260 nm, with linear ranges of 1.7-139.3µM [29], 17.4-174.1µM [30], and 7.0-139.3µM [31] and LODs of 0.04µM, 1.6µM, and 1.5µM, respectively.…”

Development of New Sensitive Spectrophotometric Method for Estimation of Famciclovir Using 3-Amino Phenol

“…Literature reviewrevealed that several spectrophotometric [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] and liquid chromatographic (LC) [21][22][23][24] methods were reported for the determination of famciclovir in bulk drug and pharmaceutical dosage forms.Drug of a particular composition is marketed with various brand names. Minimal changes in the chemical composition and standard of the drug will have a profound effect on the physiological and biological activities of the patient.…”
