      Development and validation of a normal-phase HPTLC method for the simultaneous analysis of lamivudine, stavudine and nevirapine in fixed-dose combination tablets
      D. SHEWIYO*, E. KAALE, C. UGULLUM, M. SIGONDA, P. RISHA, B. DEJAEGHER, J. VERBEKE, Y. HEYDEN (Tanzania Food and Drugs Authority, P.O. Box 77150, Dares Salaam, Tanzania)

      J. Pharm. Biomed. Analysis 54, 445-450 (2011). An improved HPTLC method has been developed for simultaneous estimation of lamivudine (LVD), stavudine (STV), and nevirapine (NVP) in fixed dose formulation. HPTLC on silica gel with ethyl acetate - methanol - toluene - 25 % ammonia 12:6:12:1. The hRf value is 24 for LVD, 38 for STV and 69 for NVP. Densitometric evaluation at 254 nm. The method was linear in the range of 42-209 ng/band (LVD), 38-192 ng/band (STV) and 42-208 ng/band (NVP). The recovery values were in the range of 98.4-102.2 % for all three compounds. The method was found suitable for quality control of LVD, STV and NVP in fixed dose formulation.

      Development and validation of a stability-indicating HPTLC method for analysis of rupatadine fumarate in the bulk drug and tablet dosage form
      A.A. SHIRKHEDKAR*, R.R. THORVE, R.A. FURSULE, S.J. SURANA (*R.C. Patel College of Pharmacy Shirpur 425 405, M.S., India)

      Acta Chromatographica 20(3), 423-437 (2008). HPTLC of rupatadine fumarate on silica gel with toluene – methanol – triethylamine 20:5:1. The hRf value was 61. Quantitative determination by absorbance measurement at 264 nm. The linearity was in the range of 400–1400 ng/band (r=0.9992). The limits of detection and quantitation were 67 and 202 ng/band, respectively. Moreover, rupatadine fumarate was subjected to acid and alkaline hydrolysis, oxidation, and photochemical and thermal degradation and underwent degradation under all these conditions. The method proved to be repeatable, selective, and accurate for the analysis of the drug by statistical analysis, and is able to separate the degradation products from the drug.
