Oral vitamin K is administered to patients who have very high INR lab values and are on warfarin therapy. Due to the inability of some patients to swallow tablets, and the commercial formulation of vitamin K being available only as a tablet or an injectable emulsion, it may be necessary to compound an oral liquid formulation. When compounding batches of oral solutions, it is sometimes convenient to measure the product in unit doses. In this project, we compared liquid vitamin K in sterile water (1mg/mL) verses liquid vitamin K in Ora-Sweet (1mg/mL) stored in amber plastic syringes. Vitamin K is light sensitive and is best stored in amber containers. Vitamin K is also lipophilic and may adsorb to the plastic syringes. In this study, we investigated the feasibility of bulk compounding oral vitamin K solutions, and aliquoting them for storage in amber plastic syringes. The Vitamin K in sterile water syringes were made by mixing 45 mL of sterile water and 5 ampules, each containing 10mg/mL of vitamin K emulsion, together in an amber glass bottle for a final concentration of 1mg/mL. Thirty 1mL plastic amber syringes were filled with the mixture, capped, and placed in the refrigerator. The same process was repeated using Ora-Sweet instead of sterile water to fill thirty more plastic amber syringes. Three syringes of vitamin K in sterile water mixture, three syringes of vitamin K in Ora-Sweet mixture, and one Vitamin K reference standard were all analyzed using HPLC-UV on the day of compounding, and at day 1, 2, 4, 7, 14, 21, 30, 60, and 90. If stability is defined as 90-110% active ingredient, then Vitamin K in sterile water is stable to fourteen days, 95.3±3.5% recovery, but some samples fell below 90% recovery after 14 days. By day ninety, the recovery in SWFI syringes was 84.2±8.9%. For vitamin K in Ora-Sweet, the within-day variability was very high due to limitations in drug dissolution; as such the average concentration was not consistently above 90%. On the day of compounding, the percent recovery in the Ora-Sweet syringes was 92.7±9.9%, despite 1 hour of stirring. In conclusion, the Vitamin K in sterile water mixture can be stored in refrigerated, amber oral plastic syringes for 14 days, but plastic amber syringes were not appropriate for storage of the Vitamin K in Ora-Sweet mixture.

O Diabetes Mellitus com suas complicações agudas e crônicas, é considerado um problema de saúde pública que compromete a produtividade, qualidade de vida e sobrevida dos indivíduos, envolvendo custos elevados para seu controle e terapêutica. A falta de fornecimento de materiais pode levar à prática de reutilização de seringas descartáveis para aplicação de insulina. Para conhecer melhor essa prática, optou-se por realizar este estudo que tem por objetivos descrever as características sócio-demográficas da população, avaliar a prática de aplicação de insulina, analisar a prática de reutilização, descrever as alterações mais freqüentes nos locais de aplicação e associá-las entre o Grupo A que reutiliza e o B que não reutiliza, associar as alterações mais freqüentes com o tamanho de agulha, número de aplicações de insulina fixa diária da população e relacionar o número de reutilizações com as alterações do Grupo A. O estudo é comparativo, analítico, transversal com abordagem quantitativa, foi desenvolvido no ambulatório de diabetes do Instituto da Criança do HCFMUSP. A população foi constituída de 199 pacientes (crianças e adolescentes) divididos em Grupo A que reutiliza seringas e Grupo B que não as reutiliza. A comparação das medianas de idade, tempo de doença e renda familiar entre os Grupos foi possível com o teste não paramétrico de Mann-Whitney. Os nódulos e lipohipertrofias foram comparados entre os Grupos através do teste de Fisher e para associar as complicações freqüentes com o tamanho de agulha, insulinas fixas diárias e número de reutilizações, foi usado o Qui-quadrado (2). Nas análises estatísticas foi adotado o nível de significância de 5%. O sexo feminino prevaleceu com 65,3%, a maioria provém de São Paulo capital (53,8%). A idade média do grupo A foi de 11 anos e do grupo B de 9 anos. O ensino fundamental sobressaiu-se com 51,3% nos pacientes e o fundamental incompleto 40,2% nos responsáveis. A média de renda familiar predominante foi de 1 a 2 salários mínimos 48,8%. A preferência pela seringa com agulha acoplada foi de 75,9%, compradas na farmácia (65,3%) com gasto mensal entre 20 a 79 reais (82,4%) ou seja, de 8 a 27 dólares. Um percentual de 55,8% pacientes auto-aplicam a insulina, preferem o álcool de supermercado para desinfecção da tampa do frasco (58,3%) e antissepsia da pele (57,3%). Lavam as mãos antes do preparo e aplicação da insulina 97,5%. Os locais preferidos para a injeção de insulina foram os braços (92%) e a coxa (82%), houve uma média de três aplicações no mesmo local em uma semana. A estratégia comum para reutilizar a seringa foi o reencape sem limpeza prévia (60,1%), guarda dentro (50,4%) ou fora da geladeira (49,7%) em um recipiente fechado (64,7%). A dor (39,2%) e outros motivos (38,6%) foram as causas para a troca da seringa. O hospital foi o local responsável pela orientação da reutilização em 52,3% e o enfermeiro em 34,6%. O local mais apontado para as complicações foi o braço para a presença de nódulos (61,3%) e de lipohipertrofias (52,8%). Não houve associação estatística entre as complicações com o tamanho da agulha e número de insulinas fixas diárias da população. Também não houve associação estatística entre o número de reutilizações com nódulos (p=0,185) e lipohipertrofias (p=0,841) do Grupo A. Os resultados desta pesquisa corroboram com os da literatura que apontam a baixa evidência de riscos de complicações pela prática de reutilização. Outras investigações envolvendo maior número de pacientes se fazem necessárias. / Diabetes Mellitus, with its acute and chronic complications, is considered a public health issue which compromises the productivity, quality of life and the individual survival, involving high costs for its control and therapeutic. The lack of material supply leads to the practice of reusing the discarded syringes in the insulin application. A study aiming at describing socio-demographic characteristics of the population, evaluating the practice of insulin application, analyzing the practice of the reuse, describing the most frequent alterations in the site of the application and associating these alterations with the size of the needle and the number of doses of daily fixed insulin between patients who reused the syringes and the ones who did not reuse them and associate the most frequent alterations in the site with the number of reuses, was performed in order to better know this practice. The study is comparative, analytical, transversal with a quantitative approach, and it was developed at the diabetes outpatient, Child’s Institute, Clinics Hospital, School of Medicine, University of São Paulo. The population was composed by 199 patients who were divided into two groups; Group A was composed by the ones that reused the syringes and Group B were the ones that did not reuse the syringes. The comparison of age, time of disease and family income medians between the groups was possible with the Mann-Whitney non parametric test. The nodules and lipohypertrophies were compared with Fisher test and the Chi-Square (2) test was used to associate the size of the needle and daily fixed insulin. The significance level of 5% was adopted in the statistical analysis. The female gender was predominant with 65.3%, majority of which comes from the city of São Paulo (53.8%). The average age was 11 years from Group A, and 9 years from Group B. A number of 51.3% of the patients had regular background and 40.2% of the responsible ones had an incomplete background, and the predominant average income family was from 1 to 2 minimum salaries 48.8%. The preference for the syringe with coupled needle was of 75.9%, bought at drugstores (65.3%) with monthly expenses between R$ 20 and R$ 79 (82.4%). A percentage of 55.8% of the patients self-applies the insulin, prefer the alcohol from supermarkets in order to decontaminate the cover of the bottle (58.3%) and perform the antisepsis of the skin (57.3%). They wash their hands before the preparation and the insulin application (97.5%). The preferable places to apply the insulin were the arms (92%) and the thighs (82%), and there was a mean of three applications in the same place in one week. The common strategy to reuse the syringe was the recap without a previous cleaning (60.1%), keep inside (50.4%) or outside the refrigerator (49.7%) in a closed recipient (64.7%). The pain (39.2%) and other motives were the cause for changing the syringe (38.6%). The hospital was the main site responsible for orienting the reuse in 52.3% and the nurse in 34.6%. The most reported place for complications was the arm due to the presence of nodules (61.3%) and lipohypertrophies (52.8%). There was neither statistical association of these complications between Groups A and B nor relation of the size of the needle and number of daily fixed insulin. There was also no statistical association between the number of reusing with nodules (p=0.185) and lipohypertrophies (p=0.841). The results of this research corroborate with the results of the literature, which point out the low evidence of risks of complications by the practice of reuse. Other investigations involving greater number of patients are necessary.

Background:Compounded vitamin K oral liquids may be useful in some patient populations, or when an appropriate solid dosage form is not available. While vitamin K oral liquid is typically prepared with sterile water for injection (SWFI), other compounding agents may be more palatable.Objective:To evaluate stability of compounded vitamin K liquids in SWFI, Ora-Sweet, simple syrup, cherry syrup, and SyrPalta stored in amber plastic oral syringes.Methods:Five types of compounded vitamin K liquids were prepared in triplicate—Ora-Sweet, simple syrup, cherry syrup, SyrPalta, and SWFI without flavoring; aliquoted into amber plastic oral syringes; and stored in a laboratory refrigerator (4.9°C to 5.4°C). On study days, 3 syringes from each batch were removed, diluted to assay concentration, and compared with a freshly prepared US Pharmacopeia reference solution. The samples and reference were analyzed using a previously validated high-performance liquid chromatography–ultraviolet method. Product stability was defined as 90% to 110% labeled amount. Results were further compared using a 2-way ANOVA (analysis of variance; P = .05) with post hoc Tukey’s correction for multiple comparisons.Results:Vitamin K in SWFI, SyrPalta, and cherry syrup was stable for 21 days, 7 days, and 24 hours, respectively, under refrigeration in amber plastic oral syringes. Vitamin K in Ora-Sweet and simple syrup demonstrated high within-day variability and low potency. Statistically significant differences were detected between the SWFI formulation and all other vehicles.Conclusion:Vitamin K in SWFI is appropriate for longer-term storage of unit-dosed vitamin K; however, SyrPalta and cherry syrup may be used for short-term storage or immediate administration of vitamin K.

Drug abusers in Taiwan are infected with HIV(Human Immunodeficiency Virus) seriously day by day in recent years. In view of this, since Aug.1,2005, C.D.C.(Center for Disease Control, R.O.C.(Taiwan)) has promoted Harm Reduction Program for drug abuse patients in control of spurting question of drug abuse/AIDS overflowing. We adopt the analysis frame of social marketing in this research to inspect the promotion of Harm Reduction Program at present government. Through questionnaire survey, we in death understand their contact situation and views of Harm Reduction Program from the mass population and the stakeholders(drug abusers). We visit 311 effective samples of opium-smoking prisoners(as drug group) to find out 84.9%(258) respondents has participated the declaration of health education of Harm Reduction Program during serving a sentence, 91.6%(282) has received information through newspaper, TV, broadcast, and brochure during serving a sentence, 89%(277) has got impression on C.D.C. slogans of ¡§Injecting drug, infecting AIDS¡¨, and the measure of offering needle and syringes exchange, methadone maintenance treatment, health education, and transferring/consulting service has accorded with the demand of drug abusers. In addition, we visit 289 effective samples of the public (as general group) to find out only 12.5% (36 ) respondents has participated the declaration of health education of Harm Reduction Program during in the past year, 53.5%(153) has received information through newspaper, TV, broadcast, and brochure during in the past year, and 55%(159) has got impression on C.D.C. slogans of ¡§Injecting drug, infecting AIDS¡¨. Both the public and opium-smoking prisoners have affirmed the promotion of Harm Reduction Program, and most has identified with the importance of the execution of Harm Reduction Program. We also find out 34%(99) respondents of the public has regarded famous actor as anti-drug spokesman can bring his attention and identification mostly, and moreover, 41%(128) respondents of opium-smoking prisoners has believed the declaration of acting as an example to others by the drug abstinence successfully is convincing most.
