Selective and non-extractive spectrophotometric determination of cefdinir in formulations based on donor-acceptor complex formation

Autor: Babita K. Singh, Dilip V. Parwate, Seema Srivastava, Sudhir. K. Shukla

Publikováno v: Química Nova, Vol 33, Iss 7, Pp 1471-1475 (2010)

Cefdinir has broad spectrum of activity and high prescription rates, hence its counterfeiting seems imminent. We have proposed a simple, fast, selective and non-extractive spectrophotometric method for the content assay of cefdinir in formulations. T

Thin-layer chromatographic selective and stability-indicating method for assay of cefixime in pharmaceuticals

Autor: S. K. Shukla, Seema Srivastava, Babita K. Singh, Dilip V. Parwate

Publikováno v: Journal of Planar Chromatography – Modern TLC. 24:524-528

A thin-layer chromatographic (TLC) method is developed for the analysis of cefixime using precoated silica gel 60F254 TLC aluminum sheets as stationary phase. The mobile phase was optimized to ensure that no other drug from cephalosporin class and de

Study on gamma and electron beam sterilization of third generation cephalosporins cefdinir and cefixime in solid state

Autor: S. K. Shukla, Dilip V. Parwate, Babita K. Singh, Indrani B. Das Sarma

Publikováno v: Radiation Physics and Chemistry. 79:1079-1087

The effect of gamma radiation from 60Co source and 2 MeV e-beam was studied on two thermolabile cephalosporin antibiotics viz cefdinir and cefixime in solid state. The parameters studied to assess radiolytic degradation were loss of chemical and micr

Effect of metal powders on γ-ray-induced decomposition of 2KNO3·La(NO3)3·2H2O

Autor: Babita K. Singh, I. B. Das Sarma, Dilip V. Parwate, R. J. Batra

Publikováno v: Radiation Effects and Defects in Solids. 164:665-672

It is a well-known fact that metals remain unaffected by electromagnetic radiation in general. However, they may be influenced to some extent by the formation of certain microstructural changes because of γ -radiation. The experimental data showed t

Radiation sterilization of fluoroquinolones in solid state: investigation of effect of gamma radiation and electron beam

Autor: Babita K. Singh, Indrani B. Dassarma, S. K. Shukla, Dilip V. Parwate

Publikováno v: Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine. 68(9)

The effect of gamma radiation from (60)Co source and 2MeV electron beam was studied on two fluoroquinolone antibiotics viz norfloxacin and gatifloxacin in the solid state. The changes in reflectance spectrum, yellowness index, vibrational characteris

Radiosterilization of fluoroquinolones and cephalosporins: assessment of radiation damage on antibiotics by changes in optical property and colorimetric parameters

Autor: Sandip Shukla, Dilip V. Parwate, Babita K. Singh

Publikováno v: AAPS PharmSciTech. 10(1)

A most common problem encountered in radiosterilization of solid drugs is discoloration or yellowing. By pharmacopoeia method, discoloration can be assessed by measuring absorbance of solutions of irradiated solid samples at 450 nm. We propose to eva
