Rapid quantitative analysis of magnesium stearate in tablets using laser-induced breakdown spectroscopy.

Purpose: Laser-induced breakdown spectroscopy (LIBS) was evaluated for its potential as a process analytical tool for the rapid determination of magnesium stearate (MgSt) distribution within and between tablets as well as between batches in a typical manufacturing run, and for the comparison of direct-compression and roller-compaction processes.

Methods: These studies were conducted using a prototype instrument and a commercial PharmaLIBS unit, both based on pulsed Nd:YAG laser radiation at 1064 nm. The intensity of a magnesium spectral line either at 517.

Rapid analysis of liquid formulations containing sodium chloride using laser-induced breakdown spectroscopy.

The purpose of this work was to demonstrate the possibilities offered by laser-induced breakdown spectroscopy (LIBS) for the direct and rapid analysis of pharmaceutical liquid formulations. Sodium chloride in solution was chosen as a model compound. A pulsed Nd:YAG laser (1064 nm) was used to produce a gaseous plasma from the liquid sample.

Safety of chewable tablets for children.

New emphasis on pediatric drug development makes the availability of safe, easy-to-use dosage formulations imperative for clinical practice. Chewable tablets are a widely used pediatric dosage form; however, a literature review on the safety of this formulation has not been published. We have, therefore, determined the safety of chewable tablets in the pediatric age group based on the published literature.
