- Description: Research describing the design, evaluation or use of pictograms for various health-related applications is receiving increasing attention in the literature. However, recent reviews of this body of literature have commented adversely on the overall quality of the research, highlighting problems with the pictogram design process, as well as calling for improvement in both the methodology and reporting of all aspects of designing, developing, modifying, evaluating and applying pictograms in practice. The heterogeneity in study design, as well as in the interventions and outcomes measured, prevents overall conclusions being drawn about the effectiveness of pictograms on comprehension and medicine-taking behaviour such as adherence and self-care. The reporting of such research should provide adequate detail to enable reproducibility and replicability of the research. This article offers guidance in designing and reporting pictogram-based research, highlighting areas that are often problematic or inadequately addressed.

- Description: The pharmacokinetics of phenylpropanolamine have been studied in healthy human volunteers following the oral administration of an aqueous solution of the drug (50 mg/200 ml). Blood and urine samples collected throughout the trial were assayed using HPLC with UV detection. The drug was shown to be rapidly absorbed with a mean tmax of 1.47 ± 0.49 h and a mean elimination half-life of 4.0 ± 0.5 h. Phenylpropanolamine is predominantly excreted via the kidney with a mean renal clearance of 0.646 ± 0.089 liter/kg/h and 90.2 ± 1.7% excreted unchanged in the urine. The data were not well described using conventional one or two body compartment models. However, the incorporation of a discontinuous absorption phase into the models resulted in an improved overall fit with better characterisation of the absorption phase.
