      HPTLC estimation of ofloxacin & tinidazole from pharmaceutical dosage form
      K.R. GUPTA*, S.G. WADODKAR (*Department of Pharmaceutical Sciences, Nagpur University, Nagpur, India)

      Indian Drugs 41 (3), 160-164 (2004). Combinations of ofloxacin and tinidazole (1:3) are available as tablet dosage forms. Stability indicating HPTLC of ofloxacin and tinidazole on silica gel with dioxan - ethyl acetate - toluene - acetic acid - water 5.5:5:3.2:2:2 . Quantification by absorbance measurement at 307 nm. The Rf value of ofloxacin and tinidazole was found to be 0.12 and 0.85 respectively. Recovery was 99.85 % and 99.45 % for ofloxacin and tinidazole respectively. The proposed method was quantitatively evaluated in terms of calibration of concentration range, stability, and accuracy. It can be adopted for routine analysis of the formulation.

      A validated HPTLC determination of stavudine in capsules
      S.G. WADODKAR, S. G. WANKHEDE, K.R. GUPTA* (*Department of Pharmaceutical Sciences, Nagpur University, Nagpur, India)

      Indian Drugs 41 (5), 300-302 (2004). Validated HPTLC method for the estimation of stavudine in capsules on silica gel with toluene - methanol 3:1. Quantitative determination by absorbance measurement at 270 nm. The linearity range of stavudine was 1.4 µg to 3.7 µg. The amount of stavudine estimated was 40.08 mg and 40.01 mg (calculated by peak height and peak area respecively) in the average weight capsule. Recovery was 99.67 % and 99.26 % calculated by peak height and peak area respectively. The proposed method is accurate, precise, selective, and reproducible and can be used for the routine analysis of stavudine.
