The application of orthogonal contrasts to determine homogeneous groups

The paper presents a modified approach to analysis of data obtained from experiments carried out according to classical factorial designs. Four examples were discussed in order to present details of proposed method. Modification of the analysis of variance presented here enables more effective use of information on how studied factors affect the means of dependent variable. The specificity of this approach is based on alternative multiple comparison procedure incorporating orthogonal contrasts to determine homogeneous groups.

Formulation and Evaluation of Floating Bioadhesive Tablet of Candesartan Cilexetil Using 32 Factorial Designs

Objective: The objective of the work is to formulate candesartan cilexetil floating bioadhesive tablets which can considerably improve the bioavailability of medicine underneath the condition of redoubled continuance of drug in abdomen. Methods: Floating bioadhesive tablet was ready by direct compression of chemical compound like HPMCE15 and Carbopol934p together. Result: After analysis of different evaluation parameter and drug release, F4 batch was selected as promising formulation for delivery of candesartan cilexetil floating bioadhesive tablets with 91.22% drug release at 12th h. Conclusion: Among the further batches, the F4 batch was selected as an optimized batch as a result of the pre-compression and post-compression parameters results area unit satisfactory. Keywords: Candesartan cilexetil, Floating bioadhesive tablets, Polymer, Total floating time.

OPTIMIZATION OF STARCH GLYCOLATE AS NOVEL SUPERDISINTEGRANT IN THE FORMULATION OF GLIPIZIDE FAST DISSOLVING TABLETS THROUGH 23FACTORIAL DESIGN

Objective: To synthesize, characterize and evaluate starch glycolate as a superdisintegrant in the formulation of Glipizide fast dissolving tablets by employing 23 factorial designs. Methods: Starch glycolate was prepared and its physical and micromeritic properties were performed to evaluate it. The fast dissolving tablet of Glipizide was prepared by employing starch crotonate as a superdisintegrant in different proportions in each case by direct compression method using 23 factorial design for the evaluation of tablet parameters like disintegration and dissolution efficiency in 5 min. Results: The starch glycolate prepared was found to be fine, free-flowing and amorphous. Starch glycolate exhibited good swelling in water with a swelling index (10%). The study of starch glycolate was shown by fourier transform infrared spectra (FTIR). The drug content (100±5%), hardness (3.5–4 kg/sq. cm), and friability (<0.15%) was been effective with regard to all the formulated fast dissolving tablets employing starch glycolate. The disintegration time of all the formulated tablets was found to be in the range of 13±0.015 to 180±0.014 sec. The optimized formulation F8 had the least disintegration time i.e., 13±0.015 sec. The wetting time of the tablets was found to be in the range of 8±0.015 to 95±0.013 sec. The In vitro wetting time was less (i.e., 8±0.015s) in optimized formulation F8. The water absorption ratio of the formulated tablets was found to be in the range of 75±0.012 to 150±0.014%. The percent drug dissolved in the optimized formulation F8 was found to be 99.95% in 5 min. Conclusion: Starch glycolate was an efficient superdisintegrant for fast-dissolving tablets. The disintegration and dissolution efficiency of the fast dissolving tablets of glipizide was good and depended on the concentration of superdisintegrant employed i.e., starch glycolate, sodium starch glycolate, crospovidone. The formulated fast dissolving tablets of glipizide exhibited good dissolution efficiency in 5 min which can be used for the fast therapeutic action of glipizide.

A Study of Educational Problem and Need of Guidance in Graduate Students

Aims of this paper to find out the Education Problems and Need of Guidance in graduate students. Here 2 x 3 factorial designs were used. In this study total 120 (60 boys and 60 girls) were randomly selected from Surat city (Gujarat, India). Out of 60 (20 first birth order, 20 second birth order and 20 third birth order) graduate students selected. Education Problems scale created by Prof. Beena Shah and Dr. S. K. Lakhera and Need of Guidance scale created by Dr. J. S. Grewal was used to collect the required data, F- test and correlation method was used for analysis of data. The Result of the study evaluated that there is no significance difference in gender variable on Education Problems and Need of Guidance in graduate students. Also there is no significance difference in birth order variable on Education Problems and Need of Guidance in graduate students. Education problems and need of guidance found 0.09 positive correlation.
