Paracetamol suppositories: a comparative study.

Abstract

Paracetamol suppositories in two different bases were given to children who had fever after operations. Plasma concentrations and the effect on temperature were compared. There was a significant correlation between peak plasma concentrations and maximum drop in temperature. A lipophilic base produced better results than a hydrophilic base.

The computational prediction of pharmaceutical crystal structures and polymorphism.

A computational method of predicting all the polymorphs of an organic molecule would be a valuable complement to polymorph screening in the developmental phase. Such a computational method is in its early stages of development, and the current methodologies, which are based on searches for the most stable lattice structure, are critically reviewed. This crude thermodynamic approach generally overestimates the propensity for polymorphism, at least for most of the molecules studied so far, showing the need to model kinetic effects as well as to refine the thermodynamic models. Although the ultimate goal of these studies is still far off, computational predictions of crystal structures have proved useful in aiding the characterisation of polymorphs from powder X-ray data, and in providing insights into the range of types of packing that may be adopted by a given molecule. Thus, computational studies already have the potential to be a valuable tool in pharmaceutical solid state science.

Phase transformation considerations during process development and manufacture of solid oral dosage forms.

The quality and performance of a solid oral dosage form depends on the choice of the solid phase, the formulation design, and the manufacturing process. The potential for process-induced solid phase transformations must be evaluated during design and development of formulations and manufacturing processes. This article briefly reviews the basic principles of polymorphism, defines the classes of phase transformation and the underlying transformation mechanisms, and discusses respective kinetic factors. The potential phase transformations associated with common unit operations employed in manufacturing solid oral dosage forms are highlighted. Specific examples are given to illustrate the importance of solid phases, and process-induced phase transitions in formulation and process development.

Micellar electrokinetic capillary chromatography and data alignment analysis: a new tool in urine profiling.

The complex nature of biofluids demands efficient, sensitive and high-resolution analytical methodologies to examine how the 'metabolic fingerprint' changes during disease. This paper describes how sulphated beta-cyclodextrin-modified micellar electrokinetic capillary chromatography (SbetaCD-MECC) has been combined with data alignment analysis and may prove a useful new tool in urine profiling, allowing for separation of over 80 urinary analytes in under 25 min. The optimised and validated SbetaCD-MECC methodology combined with data alignment analysis provides rapid identification of 'mismatches' between urine profiles which are not easily detected with the naked eye as well as a 'similarity score' which indicates the total sum of differences between one profile and another. The combination of SbetaCD-MECC with data alignment software should prove a useful alternative tool in metabonomic studies for rapid comparison of urine profiles.
