A pharmaceutical and microbiological analysis of 14 mouthwashes available in Malta were investigated, at St Luke's Hospital and the University of Malta.

Two main aims were identified, and both were concerned with the existence of fast and slow acetylators (inactivators) of isoniazid. The first aim was the determination of the distribution ratio of fast and slow metabolisers in a sample of Maltese volunteers, this quite possibly being the first time any such attempt was made locally. A secondary design of the first aim was the possible correlation of factors, other than genetic ones, with the acetylator phenotype. The second aim was an attempt at reasserting certain genetic principles with regards to the isoniazid acetylator phenotype, in a Maltese context. These principles were established in 1960 by Evans et al and stated that the isoniazid acetylator phenotype is determined by a single pair of genes located on an autosomal chromosome, with the gene for slow acetylation recessive to that for fast acetylation.

Voltammetry is a term used to describe all electroanalytical techniques, which involve the application of an external potential on the system and utilize the current-potential relationship arising at a polarizable microelectrode to calculate the concentration of the electroactive species. When the working electrode is a mercury electrode, the technique is called polarography. The purpose of this work is to illustrate the applicability of these techniques, especially polarography in pharmacy. This is because the past decase has revealed a remarkable and renewed interest in the application of electroanalytical techniques to the analysis of drugs and pharmaceuticals.
