Determination of traces of crystalline cefuroxime axetil content in cefuroxime axetil amorphous drug substance using powder X-Ray Diffraction (PXRD) Technique

چکیده
Amorphous materials are often preferred in the pharmaceutical industry due to their enhanced dissolution rate and bioavailability. Since the amorphous state is metastable and less thermodynamically stable relative to the crystalline state, there is always the potential for unexpected crystallization during storage. Conversion of amorphous to crystalline state can be evaluated by stability studies. Accurate quantification of crystalline phases present in drug materials has become increasingly imperative, due to stringent regulatory concerns about polymorph characterization. In the present study, a quantification method was developed for the determination of Crystalline phase in Cefuroxime Axetil amorphous phase using X-ray powder diffraction technique. Validation of quantification method was carried out with respect to Specificity, Precision, Linearity, Robustness, Limit of Detection and Limit of Quantification. Validation results were found to be within acceptance criteria.

Improvement in Dissolution Rate of Cefuroxime Axetil by using Poloxamer 188 and Neusilin US2
A combination of fusion and surface adsorption techniques was used to enhance the dissolution rate of cefuroxime axetil. Solid dispersions of cefuroxime axetil were prepared by two methods, namely fusion method using poloxamer 188 alone and combination of poloxamer 188 and Neusilin US2 by fusion and surface adsorption method. Solid dispersions were evaluated for solubility, phase solubility, fl...

FT-IR and Raman scattering spectra of cefuroxime axetil were proposed for identification studies of its crystalline and amorphous forms. An analysis of experimental spectra was supported by quantum-chemical calculations performed with the use of B3LYP functional and 6-31G(d,p) as a basis set. The geometric structure of a cefuroxime axetil molecule, HOMO and LUMO orbitals, and molecular electros...
