ABSTRACT
A novel, accurate, precise, sensitive, economic and rapid spectrophotometric methods has been developed and validated for simultaneous estimation of Triamterene and Benzthiazide in bulk and pharmaceutical dosage form. Triamterene and Benzthiazide showed absorption maxima at 363 nm and 283 nm in ethanol, which is used as solvent. In the present study, Area Under Curve method (Method A) developed, employedthe measurement of area at selected analytical wavelength ranges. Two analytical wavelength ranges selected were 358nm to 368nm nm (lmax of Triamterene is 363nm) and 278nm to 288nm (lmax of Benzthiazide is 283nm) for the estimation of Triamterene and Benzthiazide respectively.  Ratio derivative method (Method B) employed the measurement of amplitudes of Triamterene and Benzthiazide at their respective selected wavelengths. Two wavelengths selected were 359.2 nm and 300.4 nmfor the estimation of Triamterene and Benzthiazide respectivelybased upon divisor method.  Linearity was observed in the concentration range of 6-30 μg/ml and 3-15 μg/ml for Triamterene and Benzthiazide respectively. The recovery studies ascertained the accuracy of the proposed method and the results were validated as per ICH guidelines.

The Department of Biotechnology, Ministry of Science & Technology (Government of India) has established the Translational Health Science and Technology Institute (THSTI), an autonomous institution, as a part of the interdisciplinary Health Biotech Science Cluster, in the National Capital Region. Major Indian and overseas institutions are mentoring the development of the THSTI.

Govt. of Himachal Pradesh took up initiative in early seventies to set up a CSIR lab to make prudential use of the natural resources of the region.

Applications are invited from qualified individuals for Research Specialist position, sponsored by the National Institute of Animal Biotechnology (NIAB-DBT) project entitled “Studies on epigenetic regulation during lactation and its impact on milk biosynthesis” (NIAB/CP/107/2012).

ABSTRACT
The aim of this study was to investigate the influence of superdisintegrants on the dissolution properties of a poorly water-soluble drug from complexes prepared by kneading method. Ketoprofen was employed as a model drug. Solid dispersions prepared by kneading method exhibited higher dissolution rate and DE30 values in each case. Ketoprofen tablets were prepared by direct compression technique using microcrystalline cellulose as a directly compressible vehicle. The formulated tablets were evaluated by different In Process Quality Control tests, content uniformity and in vitro drug release study. The FTIR spectra’s study revealed that there were no interaction between polymers and drug. All the tablets formulated employing solid dispersions in superdisintegrants gave rapid and higher dissolution of Ketoprofen when compared to that of Ketoprofen plain tablets. Ketoprofen dissolution from all the tablets followed first order kinetic with correlation coefficient ‘r’ above 0.9470. All dissolution parameters (k₁, DE₃₀ and T₃₀) indicated rapid and higher dissolution of Ketoprofen from tablets formulated employing its solid dispersions in superdisintegrants when compared to plain tablets.
