A Survey on the Use of External Medications and Injection Drugs Conducted by Persons Visiting in a Health Insurance Pharmacy / 社会薬学

Since attention is sometimes required with regard to the use and handling of external medications or injection drugs in drug therapy, patients may have a feeling of “inconvenience”. We, therefore, focused on a feeling of “inconvenience when using” external medications and injection drugs, and conducted a questionnaire survey to investigate the level of awareness and current status of using assist devices that can effectively reduce such inconvenience. The survey took place at a pharmacy, and involved interviews using a questionnaire. Of the 197 respondents, valid responses were obtained from 147 individuals (74.6%). As the results, 25.9% of individuals using external medications or injection drugs responded ‘yes’ concerning the feeling of “inconvenience when using” them. In addition, 39.4% of individuals using eye drops and 10.5% of those using insulin similarly responded. However, only 10.9% knew of the availability of assist devices that are expected to reduce the inconvenience. The results revealed that a certain number of people feel the “inconvenience” of external dosage forms investigated in this study, suggesting the need for pharmacists to consider that patients may have problems using their medications, and to recommend and support the use of assist devices that can be operated by patients.

Hepatitis C: clinical and biological features related to different forms of cocaine use / Hepatite C: características clínicas e biológicas relacionadas às diferentes formas de uso da cocaína

Abstract Introduction Hepatitis C virus (HCV) infection is related with several liver diseases such as cirrhosis and hepatocellular carcinomas, leading to more than 0.5 million deaths every year and to a great global burden. It is known that injection drug users show a high prevalence of HCV infection, being considered a risk group for this disease. Cocaine users seem to be in greater risk than other drug users, and several hypotheses for this association are being studied. Aim To review data on HCV infection in cocaine users, taking into consideration the relevance of the different routes of drug administration and other risk behaviors. Methods This was a narrative review performed in the main scientific databases. Results and conclusion Data suggest that cocaine use could be associated with HCV infection due to the specificities of cocaine consumption pattern, even in those subjects who do not inject drugs, in addition to other risky behaviors, such as tattooing and unprotected sex. Injectable cocaine users seem to be more susceptible to contamination than users who do not inject drugs. However, evidence is pointing to the possibility of infection by sharing drug paraphernalia other than syringes. Moreover, specific immune system impairments caused by cocaine use are also being linked with HCV infection susceptibility, persistence and increased pathological effects.

Resumo Introdução O vírus da hepatite C (HCV) está relacionado com graves patologias hepáticas, como a cirrose e o carcinoma hepatocelular, causando mais de meio milhão de mortes todos os anos, o que reflete um problema de saúde mundial. Sabe-se que usuários de drogas injetáveis possuem alta prevalência de infecção pelo HCV, sendo por isso considerados um dos maiores grupos de risco. Usuários de cocaína parecem ter maior risco de contrair o vírus do que usuários de outras drogas, e diversas hipóteses para essa associação estão sendo estudadas. Objetivo Revisar evidências de associação da infecção pelo HCV em usuários de cocaína, considerando a relevância das diferentes formas de administração da droga e comportamentos de risco. Métodos Esta foi uma revisão narrativa realizada nos principais bancos de dados científicos. Resultados e conclusão As evidências atuais sugerem que o uso de cocaína pode estar associado com a infecção por HCV devido às especificidades do padrão de consumo da droga, mesmo naqueles indivíduos que não fazem uso de drogas injetáveis, além de outros comportamentos de risco, como tatuagens e sexo desprotegido. Usuários de cocaína injetável parecem estar mais suscetíveis à contaminação do que usuários de cocaína não injetável. Entretanto, há a possibilidade de infecção devido ao compartilhamento de outros equipamentos de uso além das seringas (cachimbos, por exemplo). Além disso, prejuízos do sistema imune causados pela cocaína também parecem estar associados com a suscetibilidade de infecção pelo HCV, além da manutenção e piora dos sintomas da doença.
