SANTA CLARA, Calif., May 15, 2012–Agilent Technologies Inc. (NYSE: A) today introduced the280-DS Mechanical Qualification System, a new instrument for routine and effortless calibration of a dissolution apparatus. The 280-DS accurately measures, verifies and documents physical ...
Irregular absorption profiles observed from diclofenac extended release tablets can be predicted using a dissolution test apparatus that mimics in vivo physical stresses. Eur J Pharm Biopharm. 2008;70(2):421–8.CrossRefPubMed 25. Davit BM, Nwakama PE, Buehler GJ, Conner DP, Haidar SH, Patel ...
Figure 12. Underlying principle of the preparation of alkalisoluble cellulose. are very low. Extremely poor correlation between Xam(C 3) and Xam(X) confirmed for cellulose with the crystal form of cellulose I having almost the same molecular weight, and for cellulose with crystal form of ...
Copley Scientific¹s pharmaceutical product range includes test equipment for: delivered dose uniformity and aerodynamic particle size measurement of metered-dose inhalers, dry powder inhalers, nebulizers and nasal sprays; as well as tablets (dissolution, disintegration, fr...
The main principle suggested is that the Q value should be set on the basis of the biobatch dissolution result (mean value of 12 units) minus 10% assuming a discriminatory method when in vivo bioequivalence has been established, as described above. The paper recommends the use of specific ...
2.2.6. Dissolution Test Dissolution tests of the tablets and the uncompacted granules were carried out using the USP dissolution apparatus II (AT7smart, Sotax, Allschwil, Switzerland) in 900 mL of 50 mM sodium phosphate buffer (pH6.8) containing 1% CTAB at 37 °C ± 0.5 with a paddle rota...
Test were done for powers of 10, between 101 and 105. No significant precision is gained by simulating meshes with more than 103 nodes (relative difference between figure of merits of subsequent simulations below 0.05%), so subsequent simulations utilized this mesh resolution. Results of these ...
4.3.2. Dissolution Test To simulate the in vivo condition of an oral administration, the dissolution tests were performed in some biorelevant fluids. All samples were sieved on a 230 mesh grid, 63 μm, (Endecotts, London, UK). The USP apparatus 2, paddle (Erweka DT-D6, Erweka GmbH, Du...
In principle, the constant K is related to the partial dissolution rate constant k and to the mass transfer coefficient h as K = 1/(1/k + 1/h). However, it is not possible to assess experimentally the relative contributions of mass transfer and dissolution on the release rate. ...
