          Abstract

          Com base em análise documental, foram discutidas e problematizadas as limitações associadas à utilização de organizadores e cortadores de comprimidos, como questão de saúde pública. Os organizadores destinados ao armazenamento e transporte de comprimidos e cápsulas expõem essas formas farmacêuticas a fatores ambientais dos quais estariam protegidos em suas embalagens originais, comprometendo sua estabilidade, eficácia e segurança. Os cortadores oferecem risco adicional quanto a perda da eficácia, reações adversas e intoxicação. Por outro lado, o transporte de medicamentos pelo usuário é reflexo da conciliação entre autonomia e autocuidado e a partição de comprimidos é necessária para cumprir certos regimes posológicos. Conclui-se que cabe aos profissionais observar e orientar pacientes e cuidadores, visando à adequação dessas condutas e à prevenção dos riscos envolvidos.

          Translated abstract

          In this essay, based on documental analysis, the limitations associated with the use of pill organizers and cutters are discussed and analyzed as a matter of public health. The use of the organizers for storing and carrying tablets and capsules exposes these medications to environmental factors from which their original packaging protected them, compromising their stability and safeness. Cutters also pose the additional risk of causing loss of efficacy, adverse reactions and overdose. On the other hand, the user carrying their own medication reflects the balance between autonomy and self-care, and splitting is sometimes required to comply with certain regimens. It can be concluded that healthcare professionals should observe and guide patients and caregivers in order to avoid risks.

          Objetivo Con base en análisis documental, se discutieron y señalaron los problemas de las limitaciones asociadas a la utilización de organizadores y cortadores de comprimidos, con respecto a la salud pública. Los organizadores destinados al almacenamiento y transporte de comprimidos y cápsulas exponen las formas farmacéuticas a factores ambientales de los cuales estarían protegidos en sus embalajes originales, comprometiendo su estabilidad, eficacia y seguridad. Los cortadores ofrecen riesgo adicional con relación a la pérdida de la eficacia, reacciones adversas e intoxicación. Por otro lado, el transporte de medicamentos por el usuario es reflejo de la conciliación entre autonomía y autocuidado, y la partición de comprimidos es necesaria para cumplir ciertos regímenes posológicos. Se concluye que resta a los profesionales observar y orientar pacientes y cuidadores, buscando la adecuación de esas conductas y la prevención de los riesgos involucrados.

          Regimen complexity and medication nonadherence in elderly patients

          Objective: To assess whether the number of daily administrations of individual drugs, as a measure of regimen complexity, contributes to the profile of an elderly patient who adheres poorly to the prescribed therapy. Population: Six hundred ninety patients over 64 years who were consecutively admitted to 11 acute medical care and three long term/rehabilitation wards in Italy. Main outcome measure: Self-reported adherence to drugs taken at home before admission was measured by a single question assessment for each listed drug supplemented with a latter question about the circumstances of the missed administration. For cognitively impaired patients the question was put to patients’ relatives or caregivers. Methods: A structured multidimensional assessment was performed to identify nonadherence and its potential correlates. Correlates of nonadherence were identified by multivariable logistic regression. Results: We recorded 44 cases (6.4%) of nonadherence to at least one drug. Being assisted by foreign caregivers (OR 2.17; 95% CI 1.02–4.63) and the use of at least one multiple daily dosing drug (OR 2.99; 95% CI 1.24–7.17) were significant independent correlates of medication nonadherence, while age, selected indexes of frailty and the cumulative number of prescribed drugs were not. Conclusion: Regimen complexity and type of assistance are independent correlates of medication nonadherence.

              External genitalia abnormalities in male rats exposed in utero to finasteride, a 5 alpha-reductase inhibitor.

              A series of studies was conducted to determine the developmental toxicity of the 5 alpha-reductase inhibitor finasteride (MK-0906) in rats. This compound was administered orally once daily to pregnant rats during various extended treatment periods during gestation. F1 offspring were evaluated on Day 20 of gestation as well as postnatally through mating to produce an F2 generation. MK-0906 treatment induced dosage-related incidences of hypospadias (penischisis) in male offspring with a threshold dosage level near 0.1 mg/kg/day and a 100% effect level of 100 mg/kg/day (with dosing through Day 20 of gestation). MK-0906 also caused decreased anogenital distance in male offspring. The dosage response for this effect (ranging from a 4.2% decrease at 0.003 mg/kg/day to a 38% decrease at 100 mg/kg/day) was more shallow than that for hypospadias. The decreases in anogenital distance were at least partially reversible postnatally with essentially complete recovery at dosages up to 0.1 mg/kg/day. There was also a dosage-related, temporary induction of nipples in F1 males. All of these effects were apparent following treatment on Days 6 through 17 of gestation but were more pronounced when dosing extended to Day 20 of gestation. Slight maternal toxicity consisting of minor decreases in body weight gain occurred only at dosages of 3 mg/kg/day and higher, indicating the selective nature of the developmental toxicity. The 5 alpha-reductase enzyme located in the rat fetal genital tubercle was studied in vitro and compared to that in the adult ventral prostate. The values for Km, Vmax, and IC50 for inhibition by MK-0906 were similar in the two tissues, suggesting that the enzymatic proteins in the genital tubercle and ventral prostate may be similar.
