consequences of erroneous selection. Aims: To design and test software to compute similarity of medicine name pairs, with a view to proactively identify LASA medicines and inform up- date of the National Tall Man Lettering List (the List). Methods: Review of international literature identified software used by America’s Food and Drug Administration for screening of proposed med- icine names. Australian academic researchers replicated and refined this software to screen all medicines in the Australian Register of Therapeutic Goods (ARTG). Composite LASA similarity scores (0.0000-1.0000) were computed. Collaboration with safety and quality experts enabled two comparisons: 1. Computed scores vs manually-calculated scores that had used a different mathematical formula and underpinned development of the 2011 version of the List 2. Computed risk category vs expert consensus risk category that also underpinned the 2011 List. Results: Complete screening of the ARTG identified 7,750 drug pairs with at least moderate (0.6600) similarity scores. Examples are primaxin vs primacin (0.9034) and mitomycin vs minomycin (0.9019). The most commonly implicated medicines used the prefix ‘pro-‘ and/or suffixes ‘-accord’, ‘-eine’, ‘ine’ or ‘en’. Computed scores and resulting risk categories demonstrated significant correlation (p<0.05) with both the manually- calculated scores and the expert-consensus risk categories. However, the expert consensus tended to amplify the consequence and significance of the name similarity and safety of LASA medicines. Discussion: The Australian software demonstrated high sensitivity in identification of potentially confusable LASA medicines, and is recom- mended to supplement incident reports in the dissemination of safety alerts and application of Tall Man lettering in clinical practice. STABILITY OF FISH OIL CAPSULES IN DOSE ADMINISTRATION AIDS T.R. Thrimawithana, R. Kaur, A. Ngo, B. So, G. Singh. Discipline of Pharmacy, RMIT University, Melbourne, VIC, Australia Ă Introduction: Fish oil supplements are commonly used to manage dis- eases such as arthritis and heart disease (1). Dose Administration Aids (DAAs) are used to improve adherence to medicines, including supple- ments. However re-packaging of medicines invalidates the physicochem- ical stability guaranteed by the manufacture (2). Aims: The aim of this study is to determine the physicochemical stability of fish oil supplements stored in dose administration aids. Methods: Fish oil capsules were repackaged in DAAs and stored at in-use condition (on a laboratory bench), at 25 o C/60 % relative humidity (RH) to simulate controlled room temperature (controlled RT) conditions and 40 o C/70 % RH (accelerated). Physicochemical stability was determined at 2 weeks, 4 weeks and 8 weeks of storage. Physical stability was determined using weight and disintegration tests. Chemical stability was determined using oxidation assessment tests specified in the European Pharmacopoeia. Results: At baseline the fish oil capsules disintegrated within 6 minute, however after 8 weeks of storage at accelerated stability conditions the time required for disintegration increased to 15 minutes. Capsules tend to burst when stored at accelerated conditions. Peroxide values and anisidine values showed a high level of oxidation with storage at accelerated con- ditions and following storage at controlled room temperature for pro- longed periods. Discussion: Physical and chemical stability of fish oil capsules are affected by storage condition and duration. If capsules are repackaged, they can be stored for up to 2 weeks at 25 o C/60 % RH or below. 1. Albert BB, et al (2013) Oxidation of marine omega-3 supplements and human health. Biomed Res Int.

McLachlan 1 . 1 Sydney Pharmacy School, The University of Sydney, NSW, Australia; 2 Department of Pharmacy, Faculty of Allied Health Sciences, University of Peradeniya, Peradeniya, Sri Lanka; 3 NSW Therapeutic Advisory Group, NSW, Australia Introduction: Antimicrobial resistance (AMR) is a major global health challenge. The education and training of pharmacy students has the po- tential to impact on patterns of antibiotic use in community and hospital settings. Aims: To investigate knowledge and antibiotic use in pharmacy students in Australian and Sri Lankan universities. Methods: A cross-sectional survey was conducted in Australian and Sri Lankan universities that offer a pharmacy degree. Pharmacy students from 17 Australian and 6 Sri Lankan pharmacy institutes were invited to participate in this study. A paper-based survey was utilised in Sri Lanka and an identical survey distributed online among pharmacy students in Australia. Descriptive data analysis and Chi square tests were performed (SPSS v24) to identify frequencies, percentages and associations. Results: 476 pharmacy students from 14 universities in Australia and 466 students from 6 universities in Sri Lanka completed the survey. The majority of students [Australia (83%) and Sri Lanka (76%)] were aged between 20-25 years and were predominately female [Australia (73%) and Sri Lanka (67%)]. Participants commonly reported previous antibiotic use [Australia (88%) and Sri Lanka (86%)]. The majority of students [Australia (89%) and Sri Lanka (77%)] reported they obtained antibiotics with a doctor’s prescription. A significantly greater number of Australian pharmacy students (92%) correctly reported that the antibiotic use was appropriate for the management of bladder infection compared to Sri Lankan students (76%), p<0.05. A significantly higher percentage of Sri Lankan pharmacy students incorrectly indicated that antibiotic use was appropriate for cold and flu (51%), body aches (11%), and headaches (6%) disease conditions compared to Australian students (15%, 2%, 1% respectively), p<0.05. Discussion: This study provides a snapshot of antibiotic use and knowl- edge among pharmacy students in a developed country, Australia and a developing country, Sri Lanka. Antibiotic use was highly prevalent among undergraduate pharmacy students in both countries. These findings identify some misconceptions about antibiotics among Sri Lankan under- graduate pharmacy students with a potential to increase the inappropriate use of antibiotics.
